共混法制备硅酸镁锂/PAAS/KOH/H2O凝胶电解质
Preparing magnesium lithium silicate/PAAS/KOH/H2O gel electrolyte by blending method
摘要
Abstract
The composite inorganic alkaline gel electrolyte of magnesium lithium silicate( MLS)/sodium polyacrylate (PAAS)/ KOH/H2O was prepared from MLS, PAAS and KOH by blending method. The samples were studied by AC impedance, cyclic voltammetry and galvanostatic charge-discharge test.At room temperature, the conductivity of prepared gel electrolyte was the same order as that of the 6 mol/L KOH solution,its electrochemical stable window was about 1.6 V. The charge-discharge efficiency of the MH/Ni battery assembled with MLS/PAAS/KOH/H2O gel dectrolyte [ m(MLS): ro(PAAS): m(KOH): m(H2O) =0.6:1.0: 5.0:15.0] was still above 95% after 250 cycles(galvanostatic charged-discharged with 1.0 C).关键词
