Electrolyte circulating system applied to metal-air battery

Abstract

The invention relates to an electrolyte circulating system applied to a metal air battery, which is used for circulating electrolyte of the metal air battery and comprises an electrolyte box, a storage box, an electrolyte box, an electrolyte circulating pump, a filtering device, an electrolyte circulating control pipe and a controller. According to the electrolyte circulating system disclosed by the embodiment of the invention, automatic preparation of the electrolyte can be realized, electrochemical reaction products in the electrolyte can be filtered out, the conductivity of the electrolyte of each single battery in each single battery pack can be improved, and the internal resistance of each single battery can be reduced; and the electrolyte circulation control pipe is arranged for each stage of single battery pack, so that the consistency of the quantity of electrolyte entering each single battery of the same single battery pack can be ensured, and the discharge capacity of the metal air battery is improved.

Description

technical field [0001] The present disclosure relates to the field of fuel cells, and in particular, to an electrolyte circulation system applied to a metal-air battery. Background technique [0002] Metal-air battery, also known as metal fuel cell, is a chemical power source that directly converts the chemical energy of metal materials 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, in 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 the metal anode. And the electrolyte of the metal-air battery often needs to be prepared in advance, and the electrolyte prepared in advance is easy to absorb carbon dioxide in the air to generate carbonate, which eventually leads to the failure of the electr...

Problems solved by technology

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.
