Abstract

The invention discloses a novel liquid injection system used for a storage type battery. The novel liquid injection system comprises a battery case, a liquid storage tank, a liquid injection valve, a gas generator and a vent valve, wherein the battery case is internally provided with a battery case cavity, a plurality of battery monomers as well as a common flow passage and a common air passage which are communicated with the gas generator; a cavity liquid injection hole is formed between the battery case cavity and the common flow passage, and battery monomer liquid injection holes are formed between the battery monomers and the common flow passage; the hole diameter of the cavity liquid injection hole is smaller than that of each battery monomer liquid injection hole; a cavity vent hole is formed between the battery case cavity and the common air passage, and vent pipes are arranged between the battery monomers and the common air passage; the liquid storage tank comprises a liquid outlet and an air inlet; the liquid injection valve comprises a liquid injection valve inlet communicated with the liquid outlet and a liquid injection valve outlet communicated with the common flow passage; and the vent valve comprises a vent valve air outlet communicated with the air inlet and a vent valve air inlet communicated with the common air passage. The novel liquid injection system is uniform in liquid injection, the common flow passage is free of electrolyte residue, and no leakage current is generated during battery discharging.

Description

technical field [0001] The invention belongs to the technical field of batteries, and in particular relates to a novel liquid injection system for a reserve battery, which is suitable for a reserve zinc-silver oxide battery that requires high liquid injection uniformity and low leakage current requirements. Background technique [0002] Due to the advantages of high specific energy, high specific power, high rate discharge and stable voltage, the reserve zinc silver oxide battery has been widely used in many occasions, especially in the field of aerospace technology, it is still the preferred power supply. [0003] Due to the special application, not only the electrical performance of the battery needs to be fully utilized, but also its automatic liquid injection system must also meet the requirements of reliability, compact structure, light weight, uniform distribution and rapid activation, which has become a technical difficulty in the development of this type of battery. ...
