Abstract—This paper reports the synthesis and performance of microporous polymer electrolyte (MPE) based on P(VDF-HFP)/CNTs Li-ion batteries. The MPE based on P(VDF-HFP)/CNTs has an interconnected uniform porous morphology with an average diameter. The MPE based on P(VDF-HFP)/CNTs with the CNTs content of 3% shows ionic conductivity of 4.36×10
-3S/cm. The MPE is stable at the higher potential more than 5.5V (versus Li+/Li). The discharge capacity of LiFePO
4 in the cell Li/GPE/LiFePO
4 is 140mAh/g at the charge-discharge rate of 0.1C. The prepared MPEs are promising materials for Li-ion batteries.
Index Terms—P (VDF-HFP), CNTs, polymer electrolyte, li-ion battery.
