This study concerns the development of awell-defined synthetic route to obtain lignin-derived multifunctional graft polymers by simple chemical modification and atom-transfer radical polymerization. By graftingion-conducting and cross-linkable moieties onto the lignin, star-shaped functional polymers are prepared. Upon cross-linking under ultraviolet light irradiation, the resulting polymer network exhibits mech anical stability even at high temperature, whereas the chain mobility is maintained despite the cross-linkedstructure. Their use as solid polymer electrolytes (SPEs) and bindersfor all-solid-state lithium metal batteries (LMBs) is also evaluated. The lignin-derived graft polymers provide afacile ion conduction pathway and also efficiently suppress lithium dendrite growth during cycling, thereby attaining excellent cycling performance for the LMB cell compared to that with aconventionalliquid electrolyte–Celgard system. |
