摘要：

Battery-grade solution products have been used for the synthesis of new types of poly(acrylonitrile) PAN-based polymer electrolyte membranes. Basically, two classes of membranes have been prepared differing by the type of lithium salt in the ethylene carbonate-dimethyl carbonate (EC-DMC) solution trapped in the PAN matrix, i.e. LiPF6, or LiC(CF3SO2)(3) lithium methide salt, respectively. The results demonstrate that both classes of membranes have high conductivity and very good chemical and electrochemical stability. These unique characteristics make the membranes suitable for applications in high-voltage, rechargeable lithium batteries. (C) 1999 Elsevier Science S.A. All rights reserved.
