Realizing high performance of solid-state lithium metal batteries by flexible ceramic/polymer hybrid solid electrolyte

Ceramic electrolytes(CEs)and solid polymer electrolytes(SPEs)are considered to be effective methods to suppress the growth of lithium dendrites.But the inferior wettability of CEs and the low ionic conductivity of SPEs limit their applications.Zhang and colleagues report in Advanced Materials that flexible ceramic/polymer hybrid solid electrolyte—prepared by in situ coupling reaction—has great promise for high-performance Li metal batteries(LMBs).Ultrahigh energy density of LMBs is catching worldwide attention,which are 2 to 6 times higher than that of lithium-ion batteries(LIBs)[1].
