Ionic conductors based on P_12TFSA plastic crystal were prepared and their thermal, electrical and electrochemical properties were examined. The prepared P_12TFSA-M(TFSA)_n (M=Li, Na or Mg; n=1 or 2) showed ionic conductivities. Li -doped P_12TFSA was prepared by keeping P_12TFSA with lithium metal at 40oC. Composite electrolytes of Li_<1.4>Al_<0.4>Ti_<1.6>(PO_4)_3 ceramic particles and P_12TFSA-LiTFSA particles were prepared and showed a conductivity of 10^<-4>S cm^<-1> at 40oC. Electrochemical Li / LiFePO_4 cells with the composite electrolyte operated as a lithium secondary battery.

制备了基于P_12TFSA塑料晶体的离子导体，并对其热学、电学和电化学性能进行了测试。制备的P_12TFSA-M(TFSA)_n(M=Li、Na或Mg；n=1或2)具有离子导电性。将P_12TFSA与金属锂保持在40oC，制备了锂掺杂的P_12TFSA。制备了Li_&lt；1.4&gt；Al_&lt；0.4&gt；Ti_&lt；1.6&gt；(PO_4)_3陶瓷颗粒和P_12TFSA-LiTFSA颗粒的复合电解液，在40oC下的电导率为10℃~(-4)·S cm~(-1)~(-1)。复合电解液的Li/LiFePO4电化学电池可作为锂二次电池使用。
