Abstract

The invention relates to the technical field of aluminum-air batteries, and discloses a large-scale aluminum-air battery pressurization and drying system; The liquid inlet of the battery pack is connected with the electrolyte tank through the liquid replenishment pipe of the electrolyte pipe, and the liquid replenishment pipe is connected with the air pipe through the electric control three-way valve A, and the electrolyte pump is installed on the liquid replenishment pipe; the battery pack The liquid outlet is connected to the electrolyte tank through the liquid return pipe of the electrolyte pipeline, and the liquid return pipe is connected to the air pipe through the electric control three-way valve B; the inlet and outlet of the bipolar plate are covered by an air cover, and the air cover The ends are respectively connected to the air pipeline through the electronically controlled three-way valve C and the electronically controlled three-way valve D; the air pipeline is connected to the fresh air device and the dehumidifier in turn. The invention not only solves the self-corrosion problem of the aluminum anode, but also solves the problem of pressurization of the air pole and the temperature control problem of the electrolyte.

Description

technical field [0001] The invention relates to the technical field of aluminum-air batteries, in particular to a large-scale aluminum-air battery pressurization and drying system and a pressurization and drying control method thereof. Background technique [0002] At present, there have been many achievements in research on aluminum-air battery products at home and abroad. In foreign countries, Zhang et al. used the mechanical charging method of replacing the aluminum anode, and by replacing the electrolyte every 400km, the electric vehicle traveled 1600km; the aluminum-air battery developed by Phinergy has a range of 1000 miles (about 1600 thousand meters); in China, the Power Lithium Battery Engineering Laboratory of Ningbo Institute of Materials Technology and Engineering, Chinese Academy of Sciences developed 1000W and 3000W aluminum-air battery modules based on new graphene-based high-efficiency air cathodes in 2017 and 2018, The energy density of the battery system c...
