摘要：
Li7La3Zr1.4Ta0.6O12(LLZTO) and polyvinylidene fluoride (PVDF) composite electrolytes (LPCEs) with a high ceramic content up to 80 wt% have been developed. Hot pressing can significantly reduce the porosity of LPCEs and increase the conductivity to 1.08 x 10(-4)S cm(-1)at 60 degrees C, then the LPCEs can sustain Li plating/stripping cycling for over 1500 h, and make LiFePO4/LPCE/Li cell display a capacity retention of 86% in 200 cycles.
