Description

Technical Field

[0001] The present invention relates to the technical field of battery structures, and in particular to a lithium battery. Background Art

[0002] After more than 30 years of development, lithium batteries have become a widely used component in electrical equipment along with the development of social economy and science and technology. However, the current lithium batteries cannot meet the demand. For example, the power consumption increased due to the improvement of data processing capabilities of mobile terminals and the significant increase in power of vehicles using brushless motors have made the capacity and battery power of existing lithium batteries insufficient.

[0003] In the prior art, batteries generally use a single positive plate and a single negative plate immersed in battery fluid. The positive electrode generally uses lithium cobalt oxide, lithium manganese oxide, lithium iron phosphate and ternary materials, and the negative electrode generally uses carbon materials. The single positive and negative plates are not conducive to the improvement of battery capacity, and the conductivity of the positive and negative electrodes limits the development of battery performance. Summary of the invention

[0004] To this end, it is necessary to provide a lithium battery by arranging multiple positive plates and negative plates in parallel and coating the positive plates with conductive materials to solve the problem in the current prior art that the battery capacity of a single positive or negative plate cannot be increased and the conductivity of the positive and negative electrodes limits the battery performance.

[0005] To achieve the above object, the inventor provides a lithium battery, including a battery shell, a battery liquid, a positive electrode group, a negative electrode group and an indium selenide material;

[0006] The battery liquid is arranged in the battery housing;

[0007] The positive electrode group row is provided with a plurality of positive electrode substrates arranged side by side;

[0008] The negative electrode group is provided with a plurality of negative electrode substrates arranged side by side;

[0009] The positive electrode group row and the negative electrode group row are immersed in the battery liquid, and the positive electrode substrates and the negative electrode substrates are arranged alternately;

[0010] The surface of the positive electrode group row is provided with an indium selenide material coating.

[0011] Different from the prior art, the above technical solution has the following advantages: by arranging the positive electrode substrates side by side on the positive electrode group row and the negative electrode substrates on the negative electrode group row, the positive electrode substrates and the negative electrode substrates can be extended according to the size of the battery and arranged in various places in the battery, which is convenient for increasing the capacity of the battery; by coating the positive electrode group row with indium selenide material, the indium selenide material improves the conductivity of the positive electrode and the movement of electrolytic electrons, thereby enhancing the electrode performance of the battery.

[0012] Furthermore, the positive electrode substrate and the negative electrode substrate are arc-shaped structures, and the arc-shaped surfaces are arranged on both sides of the staggered arrangement of the positive electrode substrate and the negative electrode substrate.

[0013] By setting the two sides of the staggered positive and negative substrates as arc structures, the arc structure increases the surface area of ​​the positive and negative substrates, further increases the contact area with the electrolyte, increases the surface area of ​​the positive and negative electrodes for ion exchange, and improves the battery working efficiency.

[0014] Furthermore, the positive electrode substrate and the negative electrode substrate are of a wavy structure, and the wavy surfaces are arranged on both sides of the staggered arrangement of the positive electrode substrate and the negative electrode substrate.

[0015] By setting the two side surfaces of the staggered positive electrode substrate and the negative electrode substrate to a wavy structure, the wavy structure increases the surface area of ​​the positive electrode substrate and the negative electrode substrate, further increases the contact area with the electrolyte in the length direction of the substrate, increases the surface area of ​​the positive and negative electrodes for ion exchange, and improves the battery working efficiency.

[0016] Furthermore, the material of the positive electrode group row and the positive electrode substrate is lithium borosilicate.

[0017] By selecting lithium borosilicate disilicide as the positive electrode group interconnection and positive electrode substrate, the charge and discharge efficiency of the battery positive electrode is improved.

[0018] Furthermore, the material of the negative electrode group interconnection and the negative electrode substrate is a naphthalene-based solid material.

[0019] By selecting naphthalene solid material as the negative electrode group interconnection and the negative electrode substrate, the negative electrode has a larger capacity.

[0020] Furthermore, the surface of the indium selenide material is coated with an anti-oxidation film.

[0021] By coating the surface of the indium selenide material with an anti-oxidation film, the indium selenide material coated on the surface of the positive electrode is prevented from being rapidly oxidized. BRIEF DESCRIPTION OF THE DRAWINGS
