Abstract

The invention relates to the technical field of aluminum air batteries, and discloses a large aluminum air battery pressurizing and drying system. The system is arranged based on a battery pack and comprises a plurality of single batteries, a bipolar plate, a dehumidifier, a fresh air device, an electrolyte tank, an electrolyte pipeline and an air pipeline, a liquid inlet of the battery pack is communicated with an electrolyte tank through the electrolyte pipeline and a liquid supplementing pipe, the liquid supplementing pipe is connected with the air pipeline through an electric control three-way valve A, and an electrolyte pump is mounted on the liquid supplementing pipe; a liquid outlet of the battery pack is connected with the electrolyte tank through an electrolyte pipeline liquid return pipe, and the liquid return pipe is connected with the air pipeline through an electric control three-way valve B; an air inlet and an air outlet of the bipolar plate are covered by an air hood; the two ends of the air hood are respectively connected with the air pipeline through an electric control three-way valve C and an electric control three-way valve D; and the air pipeline is sequentially connected with the fresh air device and the dehumidifier. The self-corrosion problem of the aluminum anode is solved, and meanwhile the air electrode pressurization problem and the electrolyte temperature control problem are solved.

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...
