Abstract：Electrochemical energy storage technology is pivotal in energy conversion and storage.In an innovative approach to enhancing the energy density and thermal stability of lithium batteries,this study employs coaxial electrospinning-a subset of in-situ polymerisation techniques-to fabricate nanofibre membranes.Cathode electrodes,lithium anodes and precursor solutions are also prepared and encapsulated within the membranes to create a new composite solid-state electrolyte.Experimental testing revealed that the conversion rate of the 1,3-dioxolane monomer in the composite solid electrolyte is 99.1％,the lithium ion migration number is 0.82 and the ion conductivity at 30℃ is 1.04×10-4 S/cm.It only begins to lose weight at a high temperature of 462℃ and can still maintain 24％of undecomposed components above 600℃.These results confirm the successful enhancement of the electrochemical,energy,and thermal stability of lithium batteries.The multifunctional composite materials developed offer a promising new solution for the manufacturing of advanced lithium batteries.
