Abstract

PURPOSE:To suppress the separation of a hydrogen-occlusion alloy from the hydrogen-occlusion negative electrode of an alkaline storage battery, which results from pulverization of the alloy, by making the electrode by binding an alkali-proof synthetic resin binder and viscous agent to the surfaces of particles of the alloy. CONSTITUTION:After LaNi5 having hydrogen-occlusion ability is pulverized, the thus prepared powder is combined with a polytetrafluoroethylene powder which is easily made fibrous and easily undergoes plastic deformation and is used as a binder. Next, polyethylene oxide used as a viscous agent is kneaded into the thus prepared mixture and the polytetrafluoroethylene powder is made fibrous. After that, the thus prepared mixture is rolled and then fixed to the surfaces of a current collector by pressure, thereby making a hydrogen-occlusion electrode for a nickel-hydrogen battery. Therefore, the hydrogen-occlusion alloy powder is firmly held on the current collector and the separation of the hydrogen-occlusion alloy is prevented even when it is pulverized after repeated charge and discharge. Accordingly, it is possible to increase the cycle life of the battery by suppressing the deterioration of battery capacity.
