AI Technical Summary
Existing aluminum-air batteries suffer from inconsistencies in electrolyte temperature and composition during use, and the generation of hydrogen poses safety hazards that cannot be effectively addressed.
An electrolyte tank for aluminum-air batteries was designed, comprising a circular recess, an outlet, a return outlet, and a chamfered structure. Combined with a hydrogen treatment system, it ensures uniform distribution of electrolyte circulation and treats hydrogen through hydrogen collection, oxidation reaction, and combustion devices.
This achieves a uniform distribution of electrolyte temperature and composition, reduces the safety hazards of hydrogen, and ensures the safety and efficiency of the battery.
