Simplification of Aluminum Air Battery by Gelation Electrolyte and Investigation of Material for Cathode Electrode

Abstract

　This study devoted to developing water-activated aluminum air batteries, which could repeatedly generate electricity by adding water to the electrolyte. Two aluminum air batteries, using polymer gelation electrolyte and paper-absorbent electrolyte, have been investigated. In addition, we also considered two materials for the cathode electrode, which were carbon sheet and carbon nanotube-loaded carbon sheet. The aluminum air batteries used environmentally-friendly sodium chloride (NaCl) for the electrolyte. The developed batteries are portable and flexible, which can be used for low-power and on-demand electricity generation activated by water.
