All the metal-air batteries employed a third electrode for charging because of the difficulty in obtaining a long-life, rechargeable air electrode. Matsushita, Japan Storage, and Sanyo supplied the iron-air and zinc-air batteries installed in EV1H, EV2H, and EV4H, respectively. The nickel-iron batteries installed in EV1N were supplied by Matsushita. They used similar nickel electrodes to those in nickel-cadmium batteries, and a sintered-type iron electrode. These electrodes were isolated by a thin, microporous resin separator. The development of manufacturing technology to reduce costs and a study to improve the charge-discharge efficiency of this battery are now in progress. The lead-acid batteries used in the route bus EV5 were of tubular type and supplied by Yuasa. Shin-Kobe supplied the lead-acid batteries used in EV3P and EV4P. The batteries installed in the latter vehicle were of a pasted-plate with the positive electrodes covered in a special mat.
