The article presents information related to the suppression of electrolyte creepage with polymer hydrogel electrolyte for nickel/metal hydride batteries. Several studies on solid or gel electrolytes have been made for nickel/metal hydride and related batteries. Considerable attention has been paid to sealing Ni/ MH cells to avoid electrolyte leakage. Especially, creepage of alkaline electrolyte occurs easily along metal sealing surfaces connected with the negative electrode. It is suggested that residual oxygen in the gas phase was dissolved into the thin electrolyte layer covering the electrode and then reduced on the electrode surface.
