Description

Technical Field

[0001] The invention relates to the field of hydrogen energy, and in particular to a hydrogen liquid and lithium ion combined battery using liquid phase trihydrogen cations as hydrogen electrodes, and a preparation method and a charging method thereof. Background Art

[0002] With the transformation of the global energy structure and higher requirements for environmental protection, hydrogen energy has become the best energy choice due to its advantages such as high efficiency, low emissions and renewability. However, the current definition of hydrogen energy is a system that uses hydrogen as energy, but hydrogen has problems such as storage, transportation and safety. Hydrogen fuel cells, the main product of hydrogen energy applications, have problems such as high cost and low lifespan. At the same time, the cost of hydrogen production is high, which limits the application of hydrogen energy.

[0003] The present invention provides a truly usable hydrogen energy technology product, which uses lithium ion batteries as production raw materials. The inventor has used very mature liquid phase trihydrogen cation charging technology to add battery liquid required by hydrogen liquid batteries into the original lithium ion batteries for charging, and the original lithium ion batteries are changed into hydrogen liquid and lithium ion combination batteries with liquid phase trihydrogen cations as hydrogen electrodes, and are also a secondary battery. The output energy of the hydrogen liquid and lithium ion combination battery can be equivalent to gasoline, and energy can be replenished by charging with liquid phase trihydrogen cation charging equipment, and energy can also be replenished by replacing hydrogen liquid battery liquid. The invention is characterized in that, since lithium ion batteries are used as production materials for hydrogen energy, products currently using lithium ion batteries can be quickly, simply, very conveniently and at low cost converted into hydrogen energy products.

[0004] In view of this, the present invention is proposed. Summary of the invention

[0005] The object of the present invention is to provide a hydrogen liquid and lithium ion combination battery with liquid phase trihydrogen cation as hydrogen electrode, and a preparation method and a charging method thereof. The maximum output voltage of the hydrogen liquid and lithium ion combination battery can reach above 4.7V, the maximum charging voltage can reach above 4.9V, the charging current can reach 1C, the output energy has no attenuation, and has good practical application prospects.

[0006] The invention provides a hydrogen liquid and lithium ion combined battery with liquid phase trihydrogen cations as hydrogen electrodes. The hydrogen liquid battery uses liquid phase trihydrogen cations as reference zero electrodes, liquid phase carbon ions as negative electrodes, and liquid phase lithium ions as positive electrodes.

[0007] The voltage between liquid trihydrogen cation and liquid carbon ion is -3.7V, the voltage between liquid trihydrogen cation and liquid lithium ion is +1.0V, and the voltage of hydrogen liquid battery is 4.7V. Hydrogen liquid battery and lithium ion battery are in a series battery relationship electrically; among them, lithium ion battery is 0-4V voltage battery, and hydrogen liquid battery is 4-4.9V voltage battery. Lithium ion battery provides output channel for DC power of hydrogen liquid battery, and hydrogen liquid battery outputs DC power for charging lithium ion battery.

[0008] The present invention also provides a method for preparing a hydrogen liquid and lithium ion combination battery, comprising: using an original lithium ion battery with lithium and lithium alloy as positive electrode materials, carbon and carbon alloy as negative electrode materials, and a hydrocarbon organic liquid (such as carbonate, etc.) as a solvent electrolyte as a production material, adding an electrolyte required for the designed capacity of the hydrogen liquid battery to the original lithium ion battery, and then using a liquid phase trihydrogen cation generating charging device to charge the original lithium ion battery, thereby changing the original lithium ion battery into a hydrogen liquid and lithium ion combination battery with liquid phase trihydrogen cations as hydrogen electrodes.

[0009] Charging the original lithium-ion battery with a liquid phase trihydrogen cation charging device includes: first charging from a voltage of 3V to a voltage of 4.9V, and then discharging to a voltage of 3V; the above process is cycled three times, and when the shell temperature of the lithium-ion battery is detected to be less than 35°C at an ambient temperature of 20°C, a hydrogen liquid and lithium-ion combination battery with liquid phase trihydrogen cation as a hydrogen electrode is prepared.

[0010] The present invention also provides a charging method for a hydrogen liquid and lithium ion combined battery. When the voltage of the hydrogen liquid battery drops below 4.1V, the battery liquid in the hydrogen liquid battery shell can be replaced for charging.

[0011] The hydrogen liquid and lithium ion combination battery is connected to the battery liquid storage box through a battery liquid input pipe, and the hydrogen liquid and lithium ion combination battery is connected to the battery liquid recovery box through a battery liquid output pipe; when charging, the discharged battery liquid in the hydrogen liquid and lithium ion combination battery is first recovered into the battery liquid recovery box, and then the fully charged battery liquid in the battery liquid storage box is injected into the hydrogen liquid and lithium ion combination battery.

[0012] The liquid hydrogen and lithium ion combination battery is charged with a liquid phase trihydrogen cation charging device. Charging is stopped when the charging voltage is above 4.9V. Then, the liquid hydrogen and lithium ion combination battery is discharged with a 0.1C current, and the battery capacity is measured at the same time. When the voltage of the liquid hydrogen and lithium ion battery drops to 4.1V, the battery capacity measured at this time is the capacity of the liquid hydrogen battery, and the capacity data is stored. The liquid hydrogen and lithium ion combination battery is continuously discharged with a 0.1C current and the battery capacity is measured at the same time. When the voltage of the liquid hydrogen and lithium ion combination battery drops to 3.99V, the battery capacity at this time is the mixed output capacity of the liquid hydrogen battery and the lithium ion battery. At this time, the battery capacity data is stored, and the liquid hydrogen and lithium ion combination battery is continuously discharged with a 0.1C current, and the battery capacity is measured at the same time. When the voltage of the liquid hydrogen and lithium ion combination battery drops to 3V, the discharge is stopped, and the battery capacity data at this time is recorded. The battery capacity data at this time is the battery capacity of the lithium ion battery and the battery capacity data is stored. The total battery capacity of the liquid hydrogen and lithium ion combination battery is the sum of the battery capacity data stored in the three stages.

[0013] Hydrogen has four allotropes: hydrogen atoms, hydrogen gas containing two hydrogen atoms, hydrogen molecules composed of three hydrogen atoms, and metallic hydrogen. Molecules composed of three hydrogen atoms are unstable molecules and cannot be formed in general chemical reactions, but can be obtained by bombarding hydrogen atoms in the ground state with hydrogen gas molecules. Hydrogen molecules composed of three hydrogen atoms can easily lose electrons and become trihydrogen cations. Trihydrogen cations are the simplest stable polyatomic molecules. Trihydrogen cations are widely present in the universe and have been detected in planets such as Jupiter, Saturn, and Uranus. Science now believes that because the temperature and density of interstellar space are very low, trihydrogen cations can exist stably in the universe. The discovery of the existence of trihydrogen cations, the artificial generation of trihydrogen cations, and the discovery of the infrared spectrum of trihydrogen cations are all trihydrogen cations in the gas phase. Studies on trihydrogen cations in the gas phase are all applied to interstellar chemistry. At present, there are no public reports of the existence of trihydrogen cations in the liquid phase in the world, let alone the invention and products of hydrogen liquid batteries.

[0014] Liquid compounds of hydrogen are present in huge amounts on Earth. Seawater, fresh water, gasoline, diesel, kerosene, ethanol, liquid glucose, etc. are all liquid compounds of hydrogen and other molecules.

[0015] Existing scientific knowledge holds that hydrogen is liquid at temperatures between -258 and -252 degrees Celsius, and gas at temperatures above -253 degrees Celsius. There is no way to make liquid hydrogen batteries.

[0016] In 2014, the inventor studied whether it is possible to use a new charging technology to regenerate and restore waste lead-acid batteries without disassembly. The lead sulfate produced on the positive and negative plates inside the waste lead-acid battery during use makes the lead-acid battery unable to be charged, which is a world problem that has not been solved for more than 150 years since the invention of the lead-acid battery. In 2006, in order to solve the charging problem of lithium-ion batteries, the inventor invented a unique charging technology, which unexpectedly restored the initial capacity of old lithium-ion batteries. The inventor experimented with the charging technology to regenerate and charge the waste lead-acid batteries, and the result was that the waste lead-acid batteries also restored the designed capacity; and hundreds of waste lead-acid batteries were treated with this method, achieving exactly the same effect. Lithium-ion batteries and lead-acid batteries are batteries with completely different properties and materials. After analysis, the inventor believes that the lead sulfate on the lead-acid battery plate is a molecule synthesized by lead atoms, sulfur atoms and oxygen atoms. The charging technology of the present invention should produce liquid trihydrogen cations in the lead-acid battery electrolyte liquid. The liquid trihydrogen cations are reduced to sulfuric acid and water with the oxygen atoms and sulfur atoms in the lead sulfate. The lead on the negative plate and the lead dioxide on the positive plate return to their original positions, turning into a new lead-acid battery. Because the lead-acid battery is a sealed structure, the reaction process cannot be directly observed with the naked eye.

[0017] Since there is no information, book, or textbook to prove the existence of liquid phase trihydrogen cations. In order to verify the existence of liquid phase trihydrogen cations, the inventor developed a device in 2016, which can charge sodium chloride brine in an open atmosphere environment through the charging technology of the present invention, so that the hydrogen atoms in the water molecules become liquid phase trihydrogen cations. In the experiment, the inventor observed with his eyes that the charging method of the present invention disintegrated the water molecules, and the oxygen atoms combined with the metal ions in the water to generate yellow oxide microparticles. The hydrogen atoms in the water molecules should generate liquid phase trihydrogen cations and exist stably in the water. In order to verify the inventor's analysis and judgment, the present invention compares the pH value of the sodium chloride brine before charging with the change of the pH value of the liquid after charging. The pH value of the sodium chloride brine before treatment is about 7.45 to 7.50, which is a weak alkaline liquid. The pH value of the liquid did not change after charging, proving that the hydrogen atoms did not generate hydrochloric acid with the chlorine atoms. The treated sodium chloride brine has no salty taste, and the sodium chloride brine has become a water-based liquid hydrogen battery with liquid phase trihydrogen cations as the positive electrode material and chloride ions and sodium ions as the electrolyte. The inventor used a liquid chromatograph to detect the components in the liquid of the water-based hydrogen liquid battery. This liquid chromatograph does not have a chromatogram of liquid phase trihydrogen cations, so it is impossible to verify the liquid phase trihydrogen cations. The inventor can only use the content of chloride ions to indirectly prove the energy of liquid trihydrogen cations. The inventor used effective chlorine test paper to test it. When the charging current is large, the content of effective chlorine is also high.

[0018] If liquid-phase trihydrogen cations can exist stably in water-based hydrogen liquid batteries, it proves that liquid-phase trihydrogen cations are also stable molecules as gas-phase trihydrogen cations. The inventors conducted a storage test, placing the water-based hydrogen liquid battery liquid containing liquid trihydrogen cations in a sealed plastic barrel, excluding the air and leaving it for one year. The chloride ion content of the hydrogen liquid battery liquid before and after one year did not change, which indirectly proves that liquid-phase trihydrogen cations can exist stably in water and do not produce any chemical reaction with water molecules.

[0019] The negative electrode of a hydrogen liquid battery with a liquid phase trihydrogen cation battery as the positive electrode should be composed of carbon atoms or oxygen atoms. The inventor conducted an electrochemical reduction test of a hydrogen liquid battery. The present invention first conducted an oxygen reduction test: in a sealed plastic barrel, half of the volume is hydrogen liquid battery liquid, and half of the volume is air. The oxygen content in the air is about 29%. After being placed for half a year, the plastic barrel deforms, and the air pressure in the plastic barrel becomes negative pressure. The chloride ions of the hydrogen liquid battery disappear, and the liquid becomes sodium oxide salt water again, and the salty taste returns. This proves that the liquid phase trihydrogen cations are reduced to water molecules with oxygen, and the chloride ions and sodium ions become sodium chloride molecules.

[0020] In the second step, the inventor conducted a carbon reduction test. Glucose molecules are synthesized from carbon, hydrogen and oxygen. The inventor added glucose liquid to the hydrogen liquid battery, and the hydrogen liquid battery was immediately reduced to sodium chloride brine. The test results were exactly the same as those of oxygen reduction. The inventor also regenerated hydrogen liquid batteries with hydrogen liquid batteries reduced by oxygen and hydrogen liquid batteries reduced by glucose liquid, and there was no change in performance and characteristics. This experiment proves that hydrogen liquid batteries are batteries that can be repeatedly charged and regenerated, unlike hydrogen fuel cells, which are single-use batteries that cannot be reduced and regenerated by charging after being discharged. In order to verify consistency, the inventor also conducted the same test on potassium chloride brine and calcium chloride brine as on sodium chloride brine, and the test results were exactly the same as those of sodium chloride brine.

[0021] The inventor has spent nearly eight years to successfully develop liquid phase trihydrogen cation generation technology and equipment, discovered the existence of liquid phase trihydrogen cations, proved that liquid phase trihydrogen cations are stable liquid molecules, and developed a hydrogen liquid battery with liquid phase trihydrogen cations as hydrogen electrodes for practical application, which is mature and feasible in theory and technology.

[0022] The inventor has been researching and developing a hydrogen liquid and lithium ion combination battery with liquid phase trihydrogen cation as the hydrogen electrode for practical application since 2022. The inventor has selected lithium ion battery electrolyte as the raw material liquid, carbonate is a hydrocarbon organic liquid, and the same organic liquids include gasoline, diesel, kerosene, etc., using liquid phase trihydrogen cation generation technology, the original lithium ions of the electrolyte solvent carbonate are used as production materials, and the original lithium ion battery is charged with a liquid phase trihydrogen cation charging device to make a hydrogen liquid and lithium ion combination battery with liquid phase trihydrogen cation as the hydrogen electrode. The content of hydrocarbon organic liquid solvent in the electrolyte of the lithium ion battery reaches about 70% of the total volume. The total amount of electrolyte in each original lithium ion battery is more than the amount required by the design, and these extra electrolytes can be used to become a hydrogen liquid and lithium ion combination battery with liquid phase trihydrogen cation as the hydrogen electrode using the technology of the present invention. The inventor selected hundreds of lithium-ion batteries of different sizes and capacities from well-known original lithium-ion battery manufacturers and verified their technology. All of them successfully realized the transformation of the original lithium-ion battery into a hydrogen liquid and lithium-ion combined battery with liquid trihydrogen cation as the hydrogen electrode. The capacity of the combined battery is the sum of the capacities of the two batteries, and the maximum output voltage can reach above 4.7V.

[0023] Carbonate solvent is an explosive and flammable liquid like gasoline. The main reason for the explosion and combustion of lithium-ion batteries is the hydrocarbon organic liquid solvent. Safety is the first priority when using the technology of the present invention. The inventors used ethanol, which is also a hydrocarbon organic liquid and is explosive and flammable, to conduct experiments. The inventors selected ethanol aqueous solution for open-loop experiments. The content of ethanol reached a level where ethanol gas can be directly ignited with a lighter on the liquid surface. The inventors conducted liquid-phase trihydrogen cation generation charging under atmospheric conditions and repeated the experiment for dozens of times. The hydrogen atoms in the ethanol molecules did not turn into hydrogen, otherwise hydrogen would combust and explode when combined with oxygen. It was also observed that the oxygen atoms in the ethanol molecules formed yellow oxides with the metal ions in the liquid. The ethanol aqueous solution was changed from colorless to yellow. No combustion or explosion accidents occurred in the inventors' test, proving that the liquid-phase trihydrogen cation generation technology of the present invention is safe.

[0024] The safety of hydrogen liquid batteries with liquid trihydrogen cations as hydrogen electrodes is a very important indicator. Since hydrogen liquid batteries are generated from carbonate solvents of lithium ion battery electrolytes as raw material liquids, carbonate solvents are a thermal energy substance. According to the law of conservation of energy in physics, the technology of the present invention converts the thermal energy of carbonate solvents into DC power, which explains from a theoretical perspective that hydrogen liquid batteries should be intrinsically safe batteries. When the inventors were charging hydrogen liquid batteries, the battery shell temperature was lower than 37 degrees. The charging voltage of the present invention reached a maximum of 4.9V or more, and the charging current reached 1C. Under the same charging conditions, lithium ion batteries will generate high temperatures and may explode. During the charging process of hydrogen liquid batteries, the shell temperature did not change much relative to the ambient temperature, indicating that the charging conversion efficiency of hydrogen liquid batteries should be above 90%, and the test results of the present invention are also very consistent with the safety theory. The samples studied by the inventors were upgraded from lithium ion batteries. Each lithium ion battery has a safety valve, which will automatically open when the internal temperature of the battery reaches a certain value, and will automatically close when the temperature drops. The inventor experimented with opening the safety valve of the lithium-ion battery by increasing the internal pressure of the hydrogen liquid battery, and tested whether the hydrogen liquid battery would burn and explode when it encountered oxygen. The test result showed that the hydrogen liquid battery produced a reduction reaction with oxygen, and the battery voltage immediately dropped to zero. Oxygen was like a safety fuse for the hydrogen liquid battery, but the hydrogen in the hydrogen fuel cell would immediately burn and explode when it encountered oxygen.

[0025] The total amount of electrolyte in each lithium-ion battery is more than the amount required by the design. These extra electrolytes can be transformed into a hydrogen liquid and lithium ion combination battery with liquid trihydrogen cations as electrodes using the technology of the present invention. The inventor selected hundreds of lithium-ion batteries of different sizes and capacities from well-known lithium-ion battery manufacturers to verify the technology of the present invention, and all of them successfully achieved the conversion of excess electrolyte in lithium-ion batteries into hydrogen liquid and lithium ion combination batteries with liquid trihydrogen cations as electrodes. The capacity of the combination battery is the sum of the capacities of the two batteries, and the maximum output voltage can reach above 4.7V.

[0026] The full charge voltage of the hydrogen liquid and lithium ion combination battery is greater than 4.7V, the output voltage of the hydrogen liquid battery is above 4.1V, the output voltage of 4.0V to 4.1V is the output voltage range of the hydrogen liquid battery and the lithium ion battery at the same time, and 3.0V to 4.0V is the output voltage range of the lithium ion battery.

[0027] The most important performance indicator of a battery is its volume-to-weight energy ratio. Through tests by the inventors, it is conservatively calculated that the volume-to-weight energy ratio of an oil-based hydrogen liquid battery using carbonate as raw material is more than 2.5 watt-hours per gram of output electrical energy, which is more than ten times greater than the volume-to-weight energy ratio of a lithium-ion battery. An oil-based hydrogen liquid battery can generate more than 2.5 kilowatt-hours of electricity per kilogram, which is similar to the volume-to-weight energy ratio of gasoline.

[0028] A hydrogen liquid and lithium ion combination battery using liquid trihydrogen cations as hydrogen electrodes, which is made from original lithium ion batteries as production materials, is a reversible battery. The inventor has conducted more than 200 charge and discharge cycle tests on a plurality of hydrogen liquid and lithium ion combination batteries using liquid trihydrogen cations as hydrogen electrodes. The output energy of the hydrogen liquid and lithium ion combination batteries using liquid trihydrogen cations as hydrogen electrodes does not decay at all.

[0029] In a hydrogen liquid and lithium ion combination battery with liquid trihydrogen cation as hydrogen electrode, the lithium ion battery part can only be charged with DC power. However, the hydrogen liquid battery can be charged with DC power like the lithium ion battery. The hydrogen liquid battery can also be charged with power by replacing the battery fluid of the hydrogen liquid battery. This feature is unique to hydrogen liquid batteries. When using a large-capacity hydrogen liquid battery, the fastest charging method is to quickly replace the battery fluid of the hydrogen liquid battery. In particular, when a hydrogen liquid and lithium ion combination battery with liquid trihydrogen cation as hydrogen electrode is used to provide DC power to electric vehicles, it can allow electric vehicle users to use it as quickly as fuel vehicles, realizing a convenient, efficient and environmentally friendly way to replenish energy.

[0030] The hydrogen liquid battery can replace the battery liquid, so that a hydrogen liquid and lithium ion combination battery with liquid trihydrogen cation as the hydrogen electrode has the function of producing hydrogen liquid battery liquid. The discharged hydrogen liquid battery liquid is injected into the shell of a hydrogen liquid and lithium ion combination battery with liquid trihydrogen cation as the hydrogen electrode. The hydrogen liquid battery liquid is charged with direct current power, and then the fully charged hydrogen liquid battery liquid is pumped out through a special liquid pump and sent to an insulated container for storage. The stored hydrogen liquid battery liquid can be transported to places where electric energy is needed by various means of transportation. The discharged hydrogen liquid battery liquid is pumped back into the shell of a hydrogen liquid and lithium ion combination battery with liquid trihydrogen cation as the hydrogen electrode for recharging, realizing a recyclable energy source with no emission, no pollution and basically no loss of direct current power. When the technology of hydrogen liquid battery advances to the point where ethanol made from potatoes, grains, and sugar products can be used as the raw material for hydrogen liquid battery liquid, it will truly realize that humans can produce energy raw materials in a green way. When photovoltaic, wind power, hydropower, and nuclear power are used to charge a hydrogen liquid and lithium ion combination battery with liquid trihydrogen cation as the hydrogen electrode, the energy problem will be truly fundamentally solved. Hydrogen liquid battery liquid can be used to transport direct current electricity to users who need energy, changing the history that electricity can only be transmitted by metal conductors. It can be imagined that electricity can be stored in plastic barrels, and direct current can be used as energy very conveniently anywhere.

[0031] The emergence of a hydrogen liquid and lithium ion combination battery with liquid trihydrogen cation as the hydrogen electrode has brought hydrogen energy into the stage of popular application and into the era of electric energy for the whole society.

[0032] A hydrogen liquid and lithium ion combination battery with liquid trihydrogen cation as hydrogen electrode is a hydrogen energy battery made of original lithium ion battery as production material. The original lithium ion battery industry chain is very complete, with huge production capacity, and has reached the stage of overcapacity. Hydrogen liquid and lithium ion combination battery will add new market demand and new industrial production methods to this industry, and become the main product of new energy.

[0033] In the more than 100 years since the invention of fuel vehicles, there are countless fuel storage stations, fuel transport vehicles, and fuel filling stations around the world. This huge production cluster can become a storage, transportation, and filling station for hydrogen liquid battery fluid. In particular, fuel filling stations can be equipped with oil-based hydrogen liquid and lithium-ion combination batteries. Adding fully charged oil-based hydrogen liquid battery fluid can be used as a DC power generation and charging station. Adding discharged hydrogen liquid battery electrolyte into the shell of the hydrogen liquid and lithium-ion combination battery and charging it with a DC charging system will become a hydrogen liquid battery fluid production station.

[0051] The original lithium-ion battery is equipped with a safety valve, which will automatically open when the internal temperature of the battery reaches a certain value, and will automatically close when the temperature drops. We opened the safety valve by increasing the internal pressure of the battery. The results showed that the battery produced a reduction reaction with oxygen, and the battery voltage immediately dropped to zero, indicating that the battery has good safety.

[0052] Example 2

[0053] This embodiment provides a preparation method of a hydrogen liquid and lithium ion combination battery of embodiment 1, comprising: adding a required amount of electrolyte to an original lithium ion battery used for manufacturing a hydrogen liquid and lithium ion combination battery according to the requirements of the hydrogen liquid battery, wherein the electrolyte uses carbonate as a solvent; subsequently, charging the original lithium ion battery using a liquid phase trihydrogen cation generating charging device to convert part of the solvent in the electrolyte into liquid phase trihydrogen cations; in liquid phase carbon ions, charging comprises: first charging from a voltage of 3V to a voltage of 4.9V, and then discharging to a voltage of 3V; the above process is cycled 3 times, and when the shell temperature of the lithium ion battery is detected to be less than 35°C at an ambient temperature of 20°C, a hydrogen liquid and lithium ion combination battery is obtained.

[0054] Example 3

[0055] This embodiment provides a charging method for the hydrogen liquid and lithium ion combination battery of Embodiment 1. When the voltage of the hydrogen liquid battery drops below 4.1V, charging is performed by replacing the battery liquid in the hydrogen liquid battery shell.

[0056] Specifically, the hydrogen liquid and lithium ion combination battery is connected to the battery liquid storage box through a battery liquid input pipe, and the hydrogen liquid and lithium ion combination battery is connected to the battery liquid recovery box through a battery liquid output pipe; when charging, the discharged battery liquid in the hydrogen liquid and lithium ion combination battery is first recovered into the battery liquid recovery box, and then the fully charged battery liquid in the battery liquid storage box is injected into the hydrogen liquid and lithium ion combination battery.

[0057] The combination battery of hydrogen liquid and lithium ion can be used for power battery, the positive and negative poles are connected to the load, and the battery shell is provided with two sealed insulating pipes for battery liquid input and output; wherein, the battery liquid input pipe is connected to the outlet of the battery liquid delivery pump through a valve, and the inlet of the battery liquid output pump is connected to the output pipe of the sealed battery liquid storage box through a valve; the battery liquid output pipe is connected to the inlet of the battery liquid recovery pump through a valve, and the outlet of the battery liquid recovery pump is connected to the sealed electrolyte recovery box through a valve. First, the battery liquid recovery pump system is turned on to recover the discharged battery liquid in the shell into the battery liquid recovery box, and then the battery liquid recovery system is closed, the battery liquid input system is turned on, and the fully charged battery liquid in the battery liquid storage box is injected into the battery shell, and the charging of the hydrogen liquid battery is completed by replacing the battery liquid.

[0058] The hydrogen liquid and lithium ion combination battery can also be used as a hydrogen liquid battery liquid charging device; specifically, the hydrogen liquid and the positive and negative poles of the lithium ion battery are connected to the liquid phase three hydrogen cation charging device, the battery shell is equipped with two sealed pipes for battery liquid input and output, the battery liquid input port is connected to the outlet of the recovery battery liquid input pump through a valve, the battery liquid recovery input pump inlet is connected to the battery recovery liquid storage box output port through a valve, the battery shell output port is connected to the battery liquid output pump inlet through a valve, and the battery liquid output pump outlet is connected to the battery liquid storage box input port through a valve. The charging process is as follows: the battery liquid in the recovery battery liquid box is pumped into the evacuated hydrogen liquid and lithium ion combination battery shell through the recovery battery pump system. After the shell is filled with battery liquid, the battery liquid input and output port valves are closed, and the liquid phase three hydrogen cation charging device is opened to charge the battery liquid in the shell. The charging voltage reaches 4.9V or more, indicating that the battery liquid has been fully charged. Close the liquid phase three hydrogen cation charging device, open the battery liquid output port valve, and pump the battery liquid in the shell into the battery liquid storage box through the battery liquid output pump system for storage, and the battery liquid charging process is completed.

[0059] In a hydrogen liquid and lithium ion combination battery with trihydrogen cations as electrodes, the lithium ion battery part uses a DC charging method to supplement electric energy, and the hydrogen liquid battery can be supplemented with a DC charging method like a lithium ion battery. In particular, the hydrogen liquid battery can also be supplemented with electric energy by replacing the battery liquid of the hydrogen liquid battery, and this feature is unique to the hydrogen liquid battery of the present invention. When using a large-capacity hydrogen liquid battery, the fastest charging method is to quickly replace the battery liquid of the hydrogen liquid battery, especially when a hydrogen liquid and lithium ion combination battery with trihydrogen cations as electrodes is used to provide DC power for electric vehicles, it can allow electric vehicle users to use it as quickly as fuel vehicles, realizing a convenient, efficient and environmentally friendly way of supplementing energy.

[0060] The hydrogen liquid battery can replace the battery liquid, so that a hydrogen liquid and lithium ion combination battery with liquid trihydrogen cation as electrode has the function of producing hydrogen liquid battery liquid. The discharged hydrogen liquid battery liquid is injected into the shell of a hydrogen liquid and lithium ion combination battery with liquid trihydrogen cation as electrode, and the hydrogen liquid battery liquid is charged with direct current power. Then, the fully charged hydrogen liquid battery liquid is pumped out by a liquid pump and sent to an insulated container for storage. The stored hydrogen liquid battery liquid can be transported to a place where electric energy is needed by means of transportation, realizing the recycling of direct current power without emission, pollution, and basically loss.
