Title:ResearchProgressonSelf-HealingPolymerBindersforSilicon(Carbon)AnodesinLithium-IonBatteries
Abstract:
Lithium-ionbatteries(LIBs)havebeenwidelyadoptedforvariousapplicationsduetotheirhighenergydensityandlongcyclelife.However,theuseofsilicon(Si)andsilicon-carbon(Si/C)compositeanodesinLIBshasfacedsignificantchallenges,includingseverevolumeexpansion,structuraldegradation,andlowelectricalconductivity.TheseissuesnotonlyresultinrapidcapacityfadingbutalsolimitthepracticalapplicationsofSi-basedanodes.Toovercomethesechallenges,theconceptofself-healingpolymershasrecentlyemergedasapromisingapproachtoenhancethestabilityandcyclingperformanceofSi(C)-basedanodes.Inthisreview,wesummarizetherecentprogressinthedevelopmentofself-healingpolymerbindersforSi(C)anodes,includingthedesignprinciples,synthesismethods,andapplications.
