[0003] In the era of rapid development of battery technology, batteries have made great progress. Scientists have made great progress in battery technology by using the principle of primary cells. Battery life and battery charging speed have also been greatly improved. However, with the development of society, the requirements for battery charging speed and safety performance are getting higher and higher. Batteries using the primary cell theory rely on the movement of electrolytes to generate directional currents. This method makes the battery itself inevitably restricted by the movement of electrolyte ions, which also limits the development of batteries. A battery that can get rid of electrolytes is needed to avoid these limitations. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] In view of the limitations of traditional batteries, the present invention provides a method for manufacturing an electrolyte-free battery and an electrolyte-free battery based on this method. The method utilizes the characteristic that when the electron flow rate capabilities of the reaction electrode and the induction electrode are inconsistent on the inner and outer sides, a reverse potential difference will be generated on the side with low flow rate capacity, thereby generating a continuous current. Since no electrolyte is used to generate current, the limitations of the electrolyte structure itself on the battery can be avoided.

[0010] In order to achieve the purpose, on the one hand, a method for manufacturing an electrolyte-free battery is invented, the specific contents are as follows:

[0011] The present invention is composed of a reaction electrode A, an induction electrode B and an inner and outer circuit with different current capabilities on both sides. In this battery structure,

[0012] The reaction electrode A is composed of an oxidizing substance, a reducing substance, a reaction carrier substance and a conductive material. The oxidizing substance refers to a substance that obtains electrons in a battery reaction, the reducing substance refers to a substance that loses electrons in a battery reaction, and the reaction carrier substance refers to a substance that participates in a battery reaction so that the reaction can proceed normally.

[0013] Catalysts and auxiliary materials that do not participate in the battery reaction can be added to the reaction electrode A to optimize the battery reaction.

[0014] In the reaction electrode A, the conductive material and the oxidizing substance or the reducing substance may be the same material.

[0015] In the reaction electrode A, the reaction carrier substance and the oxidizing substance or the reducing substance may be the same material.

[0016] The induction electrode B is composed of a strong oxidizing substance, an induction carrier substance and a conductive material, or a strong reducing substance, an induction carrier substance and a conductive material. The induction carrier substance refers to a substance that participates in the induction effect so that the induction effect can take effect. The induction effect refers to the effect that the induction electrode B is more likely to gain or lose electrons than the reaction electrode A because of its stronger overall oxidizing or reducing properties.

[0017] In the induction electrode B, the strong oxidizing substance has a stronger oxidizing property than the oxidizing substance in the reaction electrode A.

[0018] In the induction electrode B, the strong reducing substance has a stronger reducing property than the reducing substance in the reaction electrode A.

[0019] In the induction electrode B, a catalyst or an auxiliary material that does not participate in the reaction can be added to optimize the induction effect.

[0020] In the induction electrode B, the reaction of the induction electrode B can be made to participate in the battery reaction by selecting materials and adding new materials, or it can be made to not participate in the battery reaction and only play an induction role.

[0021] The outer circuit is formed by connecting one end of the resistor to the reaction electrode A and the other end to the induction electrode B. Figure 1 shown.

[0022] The inner circuit is to connect the reaction electrode A and the induction electrode B. If the current capacity of the inner circuit and the outer circuit is inconsistent, the reaction electrode A and the induction electrode B are directly connected by a wire. Figure 1 shown.

[0023] If the inductive electrode B in the battery is composed of a strong oxidizing substance, an inductive carrier substance and a conductive material.

[0024] During discharge, after the circuit is connected, electrons tend to flow from the reduced substances at the reaction electrode A through the circuits on both sides to the induction electrode B. Because the currents generated by the voltages on both sides are different, the side with smaller current generation capacity will experience a potential difference reversal to generate a reverse current, so the entire circuit generates a continuous current. The electrons returning to the reaction electrode A will give priority to satisfying the oxidizing substances to make them negatively charged, and form a stable structure with the reducing substances that have lost electrons.

[0025] It is worth noting that the currents on both sides are affected by the internal structure of the reaction electrode A, the internal structure of the induction electrode B and the resistances on both sides, and may be fluctuating.

[0026] When charging, disconnect the circuit, connect the reaction electrode A to the negative pole of the charging power supply, connect the induction electrode B to the positive pole of the charging power supply, and charge with a DC voltage to restore the reduced substance at the reaction electrode A to a high-energy state, thus completing the charging.

[0027] If the inductive electrode B in the battery is composed of a strong reducing substance, an inductive carrier substance and a conductive material, the electron movement trend is opposite to the above, the positive and negative pole connections during charging are opposite to the above, and the rest of the theory is the same as the above case.

[0028] This way of assembling batteries has no requirements on the shape and size of the battery as a whole or its components.

[0029] On the one hand, the electrolyte-free battery based on the electrolyte-free battery manufacturing method in the present invention has the following technical solutions:

[0030] The reducing substance in the reaction electrode A is one or more of lithium, sodium, beryllium, magnesium, potassium, calcium, aluminum, zinc, iron, tin and copper, and iron is selected as the reducing substance.

[0031] The oxidizing substance and the conductive material are the same material, carbon, and there is no requirement for the form of carbon. Carbon powder is selected as the oxidizing substance and the conductive material.

[0032] The strong oxidizing substance in the induction electrode B is sulfur. There is no requirement for the form of the sulfur. Sulfur powder is selected as the strong oxidizing substance.

[0033] In order to activate the sulfur element, an aluminum chloride aqueous solution with a concentration of >0 mol / L was added to the induction electrode B as a catalyst.

[0034] The conductive material is carbon, and there is no requirement on the form of carbon. Carbon powder is selected as the conductive material.

[0035] There are no special requirements for the resistor and the protective resistor in the circuits on both sides. The resistor and the protective resistor can be the same resistor. A carbon sheet is used as the protective resistor, and a 20-ohm sliding rheostat is used as the resistor.

[0036] In this battery, there is no requirement on the ratio of various materials used. DETAILED DESCRIPTION
