▎ 摘　　要

NOVELTY - Flexible aluminum air battery based on polyvinyl alcohol/ kappa carrageenan-potassium hydroxide (PVA/KC-KOH) composite gel electrolyte comprises collector (1), aluminum foil metal anode (2), PVA/KC-KOH composite gel electrolyte (3) and composite catalyst air cathode (4). USE - Flexible aluminum air battery based on PVA/KC-KOH composite gel electrolyte. ADVANTAGE - The electrolyte has wide range of adjustable solid-liquid ratio and high conductivity, inhibits leakage of open aluminum air battery, solves limitation of traditional aluminum air battery structure in terms of flexibility and is ultra-thin flexible. DESCRIPTION OF DRAWING(S) - The drawing shows schematic diagram of flexible aluminum air battery based on PVA/KC-KOH composite gel electrolyte. Collector (1) Aluminum foil metal anode (2) PVA/KC-KOH composite gel electrolyte (3) Composite catalyst air cathode (4)
