摘要

Abstract

This study investigated the important factors that affect the operating parameters of thermally regenerative ammonia-based batteries (TRABs)

including the metal electrode type

membrane type

electrode surface area

electrode distance

electrolyte concentration

and ammonia concentration. The experimental results showed that the maximum power density of TRABs with a Cu electrode was 40.0 W·m

-2

which was considerably higher than that with Ni (0.34 W·m

-2

) and Co (0.14 W·m

-2

) electrodes. TRABs with an anion exchange membrane had a 28.6% higher maximum power density than those with a cation exchange membrane. An increased electrode surface resulted in an increased maximum power but a decreased maximum power density. Within a certain range

TRAB performance was enhanced with decreased electrode distance and increased electrolyte concentration. An increased ammonia concentration resulted in enhanced ammonia transfer and improved the TRAB performance.
