Metal/air battery system capable of automatically blending electrolyte

Abstract

The invention discloses a metal / air battery system capable of automatically blending electrolyte. The metal / air battery system comprises a solution storage unit used for a metal / air battery as well asa control unit, a temperature sensor and a conductivity meter, the solution storage unit is composed of two independent seal chambers which are respectively used for storing solid-state electrolyte and used for storing water or unsaturated electrolyte solution; communication between the two seal chambers can be turned on and off, communication area can be increased and reduced, and then flow of adding solid electrolyte is regulated; and a heat exchanger is controlled to be turned on and off by acquiring a temperature signal and a conductivity signal, and increase or reduction of the communication area is controlled. Compared with the prior art, the metal / air battery system disclosed by the invention has the advantages that a use flow of the metal / air battery system is simplified, and an independent electrolyte blending device is eliminated; and a manual operation flow is reduced, and operating performance of the battery system is enhanced.

Description

technical field [0001] The invention relates to a metal / air battery system for automatically configuring electrolyte, and belongs to the technical field of metal / air batteries. 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] When the metal / air battery system is used as a backup power source, it needs to be stored for a long time and activated quickly when starting up. The high-power metal / air battery system requires a large amount of electrolyte to activate the battery for d...

AI Technical Summary

Problems solved by technology

[0003] When the metal / air battery system is used as a backup power source, it needs to be stored for a long time and activated quickly when starting up. The high-power metal / air battery system requires a large amount of electrolyte to activate the battery for discharge, and the electrolyte is mostly high-concentration Alkaline solution, long-term storage of alkaline electrolyte has high requirements on the corrosion resistance and sealing performance of the equipment, and there is a potential safety hazard of electrolyte leakage, so it is often used to temporarily configure the electrolyte solution during use, and the electrolyte solution The configuration produces a large amount of heat and irritating odor when the solid electrolyte dissolves, which has great harm to the personal health of the operator and has certain safety hazards.
