| Abstract Scope |
A metal hydride/air rechargeable battery is one of the promising candidates for next generation energy storage devices, because a high energy density and a high safety are expected at the same time from the facts that all materials are non-flammable in air and the air electrode has no limitation on discharge capacity. While the components of the air electrode are important for the performance, the internal structure strongly affects the polarization behaviors, depending on the preparation process. This paper reports a novel air electrode prepared by PDL (painting, drying, layering) method and the performance of the MH/air secondary batteries using the modified air electrode. The output performance at high current densities and the energy density under constant current operation are presented. The effects of the material of the separator and the cell configuration on the charge-discharge behaviors are also shown. |
