Proposal of NaALO₂ as an electrolyte of aluminum-air battery

Abstract

This study is about the electrolyte of aluminium-air battery. The purpose of this research is to make battery more safety and improve the performance. Today a lithium-ion battery is the mainstream in rechargeable battery. And an alkaline battery is mainstream in primary battery. There is aluminium-air battery following lithium-ion and alkaine. Aluminium is famous for energy capacity. So we tried to make same or high spec batteries. That battery electrolyte is NaAlO₂aq. Because NaAlO₂ is more safety in aluminium-air battery. We compared with NaOH at the same concentration. And we tried to experiment of the power generation characteristics using a current regulative diode. It was confirmed that aluminium-air battery using NaAlO₂, give result equality or any more performance than battery using NaOH by this experiment.
