Title: Hydrogen storage alloy electrode for metal hydride secondary battery
Inventor: TADOKORO MIKIAKI
IPC: H01M4/38
Filed: 1992-10-21
Abstract: PURPOSE:To enhance a rapidly electric charging characteristic and a high rate electric discharging characteristic of a battery by including metal powder or metal oxide powder, which is reduced at the time of electric charging/discharging so as to be turned into a metal simple substance, into a solution of a hydrogen storage alloy component forming an electrode. CONSTITUTION:A mixture of Mm, Ni, Co, Al, and Mn is heated and melted inside a high frequency melting furnace at the atmosphere of argon gas. Cu powder is added into the resultant solution, followed by cooling at a predetermined cooling speed and crushing, thus obtaining hydrogen storage alloy powder including the Cu powder. The alloy powder is mixed with a bonding agent, followed by rolling, thereby preparing alloy paste. The paste is applied to both surfaces of a negative current collector made of nickel, followed by drying, thus providing an electrode. Since a hydrogen storage alloy used for the electrode includes conductive metal powder or metal oxide powder which is reduced at the time of electric charging/discharging so as to be turned into a metal simple substance, a contact resistance between powders can be decreased owing to the powder exposed to the surface of the alloy powder. Consequently, it is possible to provide a metal/hydride secondary battery excellent in rapidly electric charging characteristic and high rate electric discharging characteristic.
