Title:
METHOD OF PRODUCING HYDROGEN STORAGE ALLOY ELECTRODE AND NICKEL-HYDROGEN BATTERY
Document Type and Number:
Japanese Patent JP2001229921
Kind Code:
A
Abstract:
To provide a hydrogen storage alloy electrode and a nickel-hydrogen battery, having highly efficient discharge characteristics and improved discharge characteristics in initial charging and discharging cycle by electrochemically activating the hydrogen storage alloy powder surface.
A process for applying plasma etching treatment to the hydrogen storage alloy powder is provided during processes for producing the hydrogen storage alloy electrode. Preferably, at least either of alkali treatment and acid treatment processes is provided as a pretreatment process for the plasma etching treatment. Furthermore, the hydrogen storage alloy electrode obtained in such a method is used as a negative electrode, to produce the nickel-hydrogen battery.
