Electrolyte Circulation System for Metal Air Batteries

Abstract

The disclosure relates to an electrolyte circulation system applied to a metal-air battery, which is used to circulate the electrolyte of the metal-air battery. The electrolyte circulation system includes an electrolyte box, a storage box, an electrolyte box, an electrolyte circulation pump, a filter device, electrolyte circulation control tube, controller. According to the electrolyte circulation system of the embodiment of the present disclosure, the automatic preparation of the electrolyte can be realized, the electrochemical reaction products in the electrolyte can be filtered out, and the conductivity of the electrolyte of each single battery in each level of single battery pack can be improved, Reduce the internal resistance of each single battery; by setting an electrolyte circulation control tube for each single battery pack, it can ensure the consistency of the electrolyte volume inside each single battery entering the same single battery pack, and improve Discharge capacity of metal-air batteries.

Description

technical field [0001] The present disclosure relates to the field of fuel cells, in particular to an electrolyte circulation system applied to metal-air batteries. Background technique [0002] A metal-air battery, also known as a metal fuel cell, is a chemical power source that directly converts the chemical energy of a metal material into electrical energy. Metal-air batteries have the advantages of abundant raw materials, high energy, low cost, and stable performance, and have broad application prospects. However, during the process of converting the chemical energy of metal materials into electrical energy, discharge products tend to accumulate inside the battery, reducing the discharge capacity of the air cathode and metal anode. Moreover, the electrolyte of metal-air batteries often needs to be prepared in advance, and the electrolyte prepared in advance is easy to absorb carbon dioxide in the air to produce carbonate, which eventually leads to the failure of the ele...

However, during the process of converting the chemical energy of metal materials into electrical energy, discharge products tend to accumulate inside the battery, reducing the discharge capacity of the air cathode and metal anode.

Moreover, the electrolyte of metal-air batteries often needs to be prepared in advance, and the electrolyte prepared in advance is easy to absorb carbon dioxide in the air and produce carbonate, which eventually leads to the failure of the electrolyte.
