Abstract

The application relates to the technical field of battery structure and especially relates to a battery which includes a shell, a liquid storage chamber, a liquid pumping structure and a pressure sensing structure. The liquid storage chamber is arranged inside the shell. A liquid storage cavity is formed in the liquid storage chamber. A first puncture film is arranged on the liquid storage chamber. The liquid storage chamber is provided with a liquid pumping opening and a liquid supplement opening. The liquid storage cavity is communicated with an electrolyte accommodating space in the shell through the liquid supplement opening. The liquid pumping structure includes a liquid pumping pipe that is provided with a first opening and a second opening. The first opening is communicated with the liquid storage cavity. The second opening is communicated with a sealing port on the shell. The pressure sensing structure includes a pressure sensing chamber, a driving member and a first puncture nail. The pressure sensing chamber is disposed in the shell. A pressure sensing cavity is arranged in the pressure sensing chamber. A cavity wall of the pressure sensing cavity includes an elastic cavity wall. A driving member is supported on the elastic cavity wall. The first puncture nail is fixed on the driving member. When the elastic cavity wall breaks, the first puncture nail, which is driven by the driving member, is moved nearby and punctures the first puncture film. The battery is not liable to cause a problem of cycling capacity sharp reduction.

Description

Technical field [0001] This application relates to the technical field of battery structure, and in particular to a battery. Background technique [0002] The electrolyte is one of the important components of the battery, and it has a vital influence on the working performance of the battery. As the battery's use time does not increase, the electrolyte will continue to be consumed. When the consumption of the electrolyte reaches the limit value, it is necessary to replenish the electrolyte in the battery. [0003] In the traditional technology, the electrolyte is usually pre-loaded into the additional liquid storage device. When the number of cycles of the battery reaches a preset value, the valve of the liquid storage device can be opened so that the electrolyte in the liquid storage device is 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 being inje...
