摘要：
Ni-MH cells comprising PVA-KOH solid polymer electrolyte and mechanically alloyed Mg2Ni as the negative electrode have been fabricated. The alkaline solid polymer electrolyte with PVA:KOH wt.% ratio of 60:40 exhibits the highest room temperature ionic conductivity of 8.5 x 10(-4) S cm(-1). This sample is mostly amorphous. The cell was charged at a constant current of 10 mA and discharged at 0.1 mA. The discharge characteristics improved upon cycling and the plateau voltage maintained above 1.2 V for similar to10 h.
