【摘要】 采用聚乙烯醇与Li2B4O7反应,并与PVDF复合成膜,制备单离子聚合物电解质。电化学测试表明,单离子聚合物电解质室温电导率在10-4S/cm以上,电化学窗口高达6V;将其浸泡于1mol/l LiPF6的PC/DMC(v:v=1:1)电解液中6h,聚合物电解质室温电导率在1013S/cm以上,最高锂离子迁移率为t+=0.81,有极大的应用前景。
【Abstract】 A single-ion polymer electrolyte was prepared by blending the reaction product of polyvinyl alcohol (PVA-403) with Li2B4O7 and PVDF.Electrochemical tests show that conductivity of the single-ion polymer e-lectrolytes at room temperature can be above 10—4 S/cm,the electrochemical window up to 6 V.After the membranes were immersed in the electrolyte(lmol/1 LiPF6 of PC/DMC(v:v =1:1) ) about 6 h,the room temperature conductivity of the achieved gel polymer electrolyte is>10-3S/cm,the optimal mobility of lithium ion(t+) was 0.81.This hybrid membrane presents great promise for practical application.
