Abstract

The invention relates to a cycling and precipitate recovering device for aluminum-air cells. The device comprises an electrolyte tank, a cooling system, an aluminum-air battery pack, a precipitate filtering system and a pressure pump, wherein a bottom output end of the electrolyte tank is connected with a liquid inlet of the cooling system, a liquid outlet of the top end of the aluminum-air cell pack is connected with an input end of the precipitate filtering system through a one-way valve, and a bottom output end of the precipitate filtering system is connected with the pressure pump. According to the cycling and precipitate recovering device for the aluminum-air cells, an electrolyte can uniformly flow without generating vortex, and Al(OH)3 flocculent deposits produced from a reaction can be rapidly deposited and are filtered off, so that the service life of the electrolyte is prolonged, and the generating efficiency of the electrolyte is improved.

Description

technical field [0001] The invention relates to a technology in the field of aluminum-air batteries, in particular to a recycling and precipitation recovery device for aluminum-air batteries. Background technique [0002] As a new type of fuel cell, the aluminum-air battery will continuously generate Al(OH) during the discharge process as the aluminum anode is consumed. 3 Deposits, deposits will be suspended in the electrolyte solution or attached to the surface of the aluminum anode, resulting in a drop in battery voltage and a drop in discharge efficiency. At the same time, during the discharge process, considerable heat will be generated, and the battery system needs to be cooled. Contents of the invention [0003] The invention aims at the defect that the existing aluminum-air battery needs to frequently replace the electrolyte and clean the electrolyte tank, and proposes an aluminum-air battery circulation and precipitation recovery device. [0004] The present inve...
