Metal/air battery system

Abstract

Disclosed is a metal / air battery system. The metal / air battery system comprises a metal / air battery pack, a liquid storage unit, a movable connecting mechanism and a fixed frame; the liquid storage unit is a closed liquid storage container prepared from a soft waterproof material at the upper part or a closed liquid storage container made of a soft waterproof material as a whole; the metal air battery system disclosed by the invention can be self-adapted to severe working conditions (inclined), so that automatic horizontal placement of the battery pack is realized, and the consistency of electrolyte flow of the battery pack is improved; and high-consistency electrolyte flow effectively controls the single-battery performance (voltage, temperature and the like), so that the discharge capacity of the system is increased, the utilization rate of an anode is improved, and the service life of the actual working condition of a cathode is effectively prolonged.

Description

technical field [0001] The invention relates to a metal / air battery system, in particular to a balance adaptive metal / air battery system. Background technique [0002] A metal / air battery is an electrochemical reaction device that uses metal (such as magnesium, aluminum, zinc, etc.) as the anode fuel, oxygen in the air as the oxidant, and lye as the electrolyte solution. my country's magnesium, aluminum, zinc and other metals are rich in reserves and low in price, so metal / air batteries have broad application prospects in many fields of mobile power sources such as communication power supplies, field emergency power supplies, lighting power supplies, and reserve power supplies. [0003] For metal / air batteries, multiple metal / air cells need to be connected in series to obtain higher output voltage; for high-power metal / air battery systems, it is often necessary to circulate the electrolyte to reduce the temperature of the battery pack. Recycled products are taken outside th...

AI Technical Summary

Problems solved by technology

In order to ensure the circulation of the electrolyte, the battery pack generally adopts a cycle method in which the electrolyte enters from the bottom and exits from the top. Multiple cells are connected through the main channel, and the fluid volume in the cells is controlled by the height of the upper liquid outlet. As the number of batteries in series increases , the difference in the flow rate of each single cell per unit time is gradually obvious, and under severe working conditions (such as the on-board power supply working at an inclined position), the flow rate of the single cell at a high inclined position decreases due to the high outlet position, and in severe cases There is even no electrolyte circulation, which leads to differences in cell temperature and discharge performance. In severe cases, the cathode is damaged due to temperature out of control
