摘要：A lotus root-like porous nanocomposite polymer electrolyte (NCPE) based on poly(vinylidene difluorideco-hexafluoropropylene) [P(VDF-HFP)] opolymer and TiO2 nanoparticles was easily prepared by a nonsolvent induced phase separation (NIPS) process. The formation mechanism of the lotus root-like porous structure is explained by a qualitative ternary phase diagram. The resulting NCPE had a high ionic conductivity up to 1.21 X 10(-3) S cm(-1) at room temperature, and exhibited a high electrochemical stability potential of 5.52 V (vs. Li/Li*), lithium ion transference number of 0.65 and 22.89 kJ mol(-1) for the apparent activation energy for transportation of ions. It is of great potential application in polymer lithium ion batteries. (C) 2008 Elsevier B.V. All rights reserved.
