Abstract

An air-metal hydride (Air-MH) battery has been studied as one of energy conversion systems with a high energy density for electric vehicles (theoretical capacity: 458 Wh-kg-1 for Air-LaNi5H6) [1,2]. The metal-hydride negative electrode of this battery is recharged by exposing it to hydrogen gas (H2-recharge), and also electrochemically recharged by use of an additional electrode for oxygen evolution. Therefore the Air-MH battery is suitable for the use in the future community in which both hydrogen gas and electricity are available. We have developed a metal hydride electrode for this battery, and showed that the electrode was recharged with hydrogen gas at the rate comparable to usual electrochemical recharging [3].
