Title: Positive electrode plate for nickel hydrogen battery
Inventor: SUZUKI HIROYUKI
IPC: H01M10/34
Filed: 1999-07-22
Abstract: PROBLEM TO BE SOLVED: To reduce the internal resistance of a battery to improve the discharge characteristic by setting the weight of nickel in a foamed nickel substrate to a specified range. SOLUTION: A foamed nickel substrate constituting a positive electrode plate is manufactured by plating a sheet foamed core material such as foamed urethane with nickel in the state where a tension is added in a fixed direction, and then removing the foamed core material by oxidation or baking. The weight of nickel of the resulting foamed nickel substrate is set to 0.5-1.1 kg/m2, preferably 0.65-0.75 kg/m2. According to this, the ohmic resistance of the foamed nickel substrate can be reduced, and the internal resistance of the battery is consequently reduced. When the weight of nickel is too much, the energy density of the battery is remarkably reduced by the increase in weight ratio of the foamed nickel substrate to the positive electrode plate (reduction in porosity). When the weight of nickel is increased to a certain degree or more, the reducing effect of resistance is saturated.
