Abstract

The present application relates to the technical field of battery structure, and in particular to a battery, which includes a casing, a liquid storage chamber, a liquid pumping structure and a pressure sensing structure, wherein: the liquid storage chamber is arranged inside the casing, and the liquid storage chamber has a liquid storage cavity , the liquid storage chamber has a first puncture membrane, and a liquid suction port and a liquid replenishment port are set up, and the liquid storage chamber is connected with the electrolyte containing space in the housing through the liquid replenishment port; the liquid pumping structure includes a liquid suction tube, and It has a first port and a second port, the first port communicates with the liquid storage chamber, and the second port communicates with the sealing port on the casing; the pressure-sensitive structure includes a pressure-sensitive chamber, a driving part and a first piercing nail, and the sensing The pressure chamber is arranged in the casing, and there is a pressure-sensing chamber inside the pressure-sensing chamber, the wall of the pressure-sensing chamber includes an elastic chamber wall, the driving member is supported on the elastic chamber wall, the first piercing nail is fixed on the driving member, and the first When the wall of the elastic cavity is ruptured, the puncture nail is driven by the driving member to approach the first puncture membrane and pierce the first puncture membrane. 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 ...
