The battery is not prone to the problem of cycle diving.

Description

technical field

[0001] The present application relates to the technical field of battery structure, in particular to a battery. Background technique

[0002] The electrolyte is one of the important components of the battery, which has a vital impact on the working performance of the battery. As the usage time of the battery increases, the electrolyte will be continuously consumed. When the consumption of the electrolyte reaches the limit value, it is necessary to replenish the electrolyte in the battery.

[0003] In traditional technology, the electrolyte is usually pre-loaded into the additional liquid storage device. When the number of cycles of the battery reaches the preset value, the valve of the liquid storage device can be opened to allow the electrolyte in the liquid storage device to be injected into the battery.

[0004] However, the electrolyte in the above-mentioned liquid storage device has been stored for a long time under normal temperature conditions before ...
