Description

Technical Field

[0001] The invention relates to a new dielectric material of a solid-state energy storage battery brick, a preparation method and application thereof, and belongs to the technical field of batteries. Background Art

[0002] At present, the demand for new energy vehicles is rising continuously. However, power batteries, as the "heart" of new energy vehicles, are in short supply and facing a "battery shortage". At present, a large number of car ordering users have encountered the embarrassing phenomenon of dealers raising prices in disguise and not being able to pick up the car for a long time. As a result, major new energy vehicle companies have also encountered a return crisis. Although many new energy vehicle companies have chosen to purchase, participate in shares, and independently develop to strive to achieve breakthroughs in the production and supply of power batteries, they have never been able to achieve their goals due to various constraints such as technical barriers, shortage of raw materials, high costs, and long production cycles.

[0003] The three most popular automotive batteries on the market currently have production problems and usage defects as follows: 1. Lithium batteries: The failure rate is high, with about 1% of the batteries failing for various reasons; they cannot tolerate overcharging or over-discharging, and excessive charging and discharging will shorten their service life; the raw materials are expensive, the production cost is high, and the material stacking density is low, which is not conducive to production control; multiple protection mechanisms are required, and improper use will not only reduce the service life but may also cause an explosion.

[0004] 2. Nickel-cadmium batteries: The cadmium in nickel-cadmium batteries is toxic, so nickel-cadmium batteries are not conducive to the protection of the ecological environment. In addition, due to numerous shortcomings, nickel-cadmium batteries have been basically eliminated from the application range of vehicle batteries.

[0005] 3. NiMH battery: There are thermal problems, large charging current, low charging efficiency, and a lot of heat; low battery specific energy; low nominal voltage, higher requirements for battery consistency and reliability; poor high temperature charging performance, thermal runaway may occur, resulting in safety problems; large self-discharge; high material cost. NiMH batteries use a lot of relatively expensive metals such as nickel and cobalt, which makes the cost of battery raw materials relatively high.

[0006] In view of this, it is indeed necessary to provide a new dielectric material formula for monomer-combined solid-state energy storage batteries with low production cost, excellent electrochemical performance and excellent safety performance. Summary of the invention

[0007] One of the purposes of the present invention is to provide a new dielectric material for solid-state energy storage battery bricks, which has a low production cost, excellent electrochemical performance and excellent safety performance. The new dielectric material formula of the monomer combination solid-state energy storage battery is used to reduce the battery production cost and improve the battery safety performance. It can achieve environmental protection of materials and green environmental protection recycling and reuse.

[0008] Another object of the present invention is to provide a method for preparing a new dielectric material for solid-state energy storage battery bricks. The process preparation process is simple, the dielectric material is environmentally friendly and in a solid state, and the environmentally friendly battery dielectric molding can greatly improve the environmental performance and energy storage performance of the battery.

[0009] Another purpose of the present invention is to be used in the field of solid-state energy storage batteries and can be expanded to infrastructure; due to its excellent energy storage characteristics, it can be used as electric heating wall tiles, electric heating floor tiles, etc. for paving the ground and building walls, and converting daytime solar energy into battery bricks for storage to continue to generate electricity. In this way, whether it is a factory or a building for heating and power generation, a large amount of electricity resources will be saved. At the same time, it has the advantages of not taking up space, being environmentally friendly, safe, non-flammable, non-explosive, and non-combustible, which will bring us huge economic benefits and environmental value. Using it in infrastructure will bring new directions in the industrial structure.

[0010] In order to achieve the above-mentioned purpose, the technical solution of the present invention is implemented as follows: a new dielectric material for solid-state energy storage battery bricks, characterized in that the formula includes: 25-26.5g of fine sea sand, 12-12.5g of diatomaceous earth, 7-8g of alum, 7-8g of sodium carbonate, 8-9g of high-purity manganese oxide, 6-6.5g of graphite conductive powder, 6.5-7g of sodium carbonate water, and 11.1 ml of pure seawater.

[0011] The fine sea sand is 25.5g of fine sea sand soaked in seawater with a mesh size of 250-300 or more.

[0012] The diatomaceous earth has a fineness of more than 300 meshes and weighs 12.2 g.

[0013] The alum is 7.5g of medicinal or edible alum.

[0014] The graphite conductive powder is ultrafine 6.3g.

[0015] The sodium carbonate solution is 6.8 g of granular edible alkali.

[0016] The sodium carbonate is 7.7g.

[0017] The high-purity manganese oxide is 8.6 g.

[0018] A method for preparing a new dielectric material for a solid-state energy storage battery brick comprises the following steps: Step 1, prepare a mixture of new solid energy storage dielectric materials: prepare in a sterile vacuum chamber, first mix the above materials evenly according to the proportion, first put in powdered materials fine sea sand 25-26.5g, diatomaceous earth 12-12.5g, alum 7-8g, sodium carbonate 7-8g, high-purity manganese oxide 8-9g, graphite conductive powder 6-6.5g, sodium carbonate water 6.5-7g, then put in liquid material pure seawater 11.1 ml, mix all and stir evenly to form a flocculent solid dielectric material for use; Step 2: Take out 10 grams of the solid dielectric material obtained in step 1, squeeze it into a 2 mm sheet and apply it on the positive electrode plate; wherein the solid dielectric material is kept in a constant temperature and humidity environment within the range of 20°C-25°C and the humidity is controlled between 30%-40%; Step three, take out the remaining solid dielectric material in step one, squeeze it around the battery, and continue to squeeze it to form a square solid to obtain an energy storage battery brick.

[0019] The positive effect of the present invention is that it can be made into an energy storage battery through simple assembly. The battery formula medium forms a voltage of 1.56 volts before charging. After 5 times of rapid charging and discharging, the voltage can reach 2.8-3.5V as measured by a multimeter. The output current is much larger than the current of a 1.5V battery, which can reach 2-3 times. The results of multiple experiments show that the current does not change much during multiple charging, but the current gradually increases during the discharge process, and the experimental light bulb becomes brighter and brighter, indicating its superior performance in energy storage. Its performance, size, weight and environmental protection are all better than other batteries. This data is measured under the condition of extremely simple packaging. Subsequent improvement of production technology and perfecting of sealing conditions can further improve the battery performance.

[0020] The solid-state energy storage battery brick of the present invention can be expanded in the field of infrastructure in terms of its application: due to its excellent energy storage characteristics, it can be used as electric heating wall bricks, electric heating floor bricks, etc. for paving and building walls, and converting daytime solar energy into battery bricks for storage and continued power generation, so that whether it is a factory or building heating power generation, it will save a lot of power resources, and at the same time, the advantages of not taking up space, environmental protection, safety, no fire, no explosion, and non-flammable will bring us huge economic benefits and environmental protection value. Use in infrastructure will bring new directions in the industrial structure. DETAILED DESCRIPTION
