Abstract

PROBLEM TO BE SOLVED: To prevent fall out of a filler due to repetition of powder charge and discharge, and restrain the occurrence of short-circuit in a battery and lowering in charge and discharge cycle life characteristics by a bonding agent including at least SBR being applied onto an electrode surface. SOLUTION: As a bonding agent to be applied onto a nickel electrode surface, when a fluorine resin is applied in addition to SBR, a battery with its further superior cyclic life characteristics can be provided. As a fluorine resin, a PTFE derivative such as polytetrafluoroethylene, trifluorochloroethylene resin or the like are exemplifed. A quantity of SBR to be applied to the nickel electrode surface is preferred to be 0.001 to 0.1 wt.% to a nickel hydroxide. In addition, a quantity of fluorine resin is preferred to be 0.05 to 0.5 wt.% to a nickel hydroxide. Such nickel electrode manufacture is performed by applying SBR, and further, dispersing liquid with added fluorine resin and drying it, and thereafter, rolling it, and adjusting it to a given thickness.
