Abstract

Abstract A Cu/Ni composite electrode is proposed for increasing the anodic coulombic efficiency and electrode operation time in thermally regenerative ammonia batteries (TRABs) used for converting low-grade waste heat into electrical power. The performance of a TRAB employing a Cu/Ni composite electrode (TRAB-Cu/Ni) is comparably studied, and the effects of the electroplating conditions are investigated. In comparison to the TRAB-Cu system, TRAB-Cu/Ni achieves similar maximum power (6.5 mW), but increased anodic coulombic efficiency (94%) and a significantly extended electrode operation time (>55 h). During electroplating, the structure of the composite electrode is influenced by the electroplating time and the concentrations of HEDP and Cu2+ in the electroplating baths. Optimal electroplating conditions for achieving maximum power (electroplating time of 60 min, HEDP concentration of 0.48 M, and Cu2+ concentration of 0.06 M) are also identified.
