Description

technical field

[0001] The invention relates to the technical field of batteries, in particular to a battery with a symmetrical double-cathode structure, a preparation method and a discharge method thereof. Background technique

[0002] Batteries in the prior art, such as rectangular parallelepiped batteries, do not consider the issue of the current collecting area of ​​the cathode and anode, but determine the length, width and height of the battery based on the total current collecting area. Then, electrons are derived from the two wide and high surfaces. Electrons are imported from the two long and wide surfaces, and the area of ​​the long and wide surfaces is obviously much larger than the area of ​​the wide and high surfaces, which results in the ability of the output electrons in the circuit to be lower than the ability of the input electrons, and the difference between the input and output in the case of the same cathode and anode reaction area is directly Affect the e...
