Tailored lithium metal/polymer electrolyte interface with LiTa_(2)PO_(8) fillers in PEO-based composite electrolyte

The unstable Li/PEO-based electrolyte interface in allsolid-state lithium metal batteries usually leads to high interfacial resistance,low Coulombie efficiency and fast lithium dendrites growth even under a low current density.The interface composition directly determines the interfacial integrity,dynamic Li^(+)/e^(-)transport processes and the subsequent Li+plating/stripping behavior;thus,it is of significance to regulate the interphase to have better safety and higher energy density for all-solid-state lithium metal batteries.Here,by incorporation of Li^+conducting LiTa_(2) PO_(8) fillers in PEO-based polymer electrolyte.
