To address these issues, the solidifica-on of LIBs by replacing liquid electrolytes with solid electrolytes has a5racted significant a5en-on . The use of inflammable solid electrolytes eliminates the aforemen-oned risks associated with liquid electrolytes, greatly improving ba5ery safety. Moreover, solid electrolytes poten-ally allow the use of Li metal anodes, which would substan-ally increase the energy density . Therefore, fully solidified LIBs, namely, all-solid-state lithium-ion ba5eries (ASSLIBs), are regarded as a next-genera-on electrochemical energy storage technology and have been the subject of extensive research and development efforts in recent years .
