Variable-Temperature Li Solid-State NMR Study to Determine Li-Ion Mobility and Its Correlation with Conductivity in Polymer Electrolytes Based on P(VdF-HFP)/P(EOEC) Blends for Li-Ion Secondary Batteries

摘要

In our previous study,in order to alleviate the problems inevitably caused by the leakage and evaporation of organic solvents in the gel polymer electrolytes, we reported the novel solvent-free polymer electrolyte based on porous poly(vinylidene fluoride-co-hexafluoro propylene) [P(VdF-HFP)]/poly(ethylene oxide-co-ethylene carbonate) [P(EO-EC)] blend membranes with pores immersed by P(EO-EC).
