Fabricating a PVDF skin for PEO-based SPE to stabilize the interface both at cathode and anode for Li-ion batteries
文献摘要：
Poly(ethylene oxide)(PEO)-based solid polymer electrolyte is always the most promising candidate for preparing thinner,lighter and safer lithium-ion batteries.However,the lithium dendrites growth of lithium anode and the high-voltage oxidation of cathode are easy to cause the PEO-based battery failure.The way to deal with the different challenges on both sides of the anode and cathode is pursued all the time.In this study,we reported a new strategy to construct the PVDF/PEO/PVDF three-layer structure for solid polymer electrolyte(marked as PVDF@PEO)using PVDF as the functional"skin".The PVDF@PEO electrolyte can effectively prevent from the lithium dendrites,and shows a stable cycling life over 1000 h in the Li/PVDF@PEO/Li cell.In addition,the PVDF@PEO electrolyte exhibits higher oxidation resis-tance and can be matched with high-voltage LiCoO2 cathode.The Li/PVDF@PEO/LiCoO2 cell delivered a specific capacity of about 150 mAh g-1 over 150 cycles and maintained good cycling stability.Our research provides insights that the polymer electrolytes constructed with PVDF functional"skin"can simultaneously meet the challenges of both anode and cathode in solid-state lithium-ion batteries(SSLIBs).
