Preparation and Electrochemical Characterization of Polymer Hydrogel Electrolytes for Nickel-Metal Hydride Batteries

摘要

Polymer hydrogel electrolytes containing various concentration of KOH have been prepared from so-called super-absorbent polymers (SAP) and KOH aqueous solution.Characteristics of the hydropgel electrolytes was examined to investigate the applicability of the hydrogel electrolyte to nickel/metal hydride(Ni/MH) battery.
