Lithium　metal　anode　(LMA)　corrosion　accelerates　capacity　degradation,　increases　interfacial　resistance,　and　causes　performance　failure　in　all　types　of　LMA-based　batteries　(LMABs).　Given　the　inevitable　calendar　aging　of　batteries,　it　is　imperative　to　investigate　the　corresponding　lithium　corrosion　mechanisms　and　develop　tailored　mitigation　strategies　to　promote　the　development　and　commercialization　of　LMABs.　This　review　first　provides　a　comprehensive　summary　of　the　different　types　of　corrosion　in　LMABs.　In　particular,　the　similarities　and　differences　of　lithium　anode　corrosion　between　different　types　of　liquid　LMABs　are　analyzed.　Secondly,　the　qualitative　and　quantitative　corrosion　characterization　methods　are　summarized,　including　the　characterization　techniques,　working　principles,　functions,　and　limitations.　Thirdly,　the　current　corrosion　mitigation　strategies　are　categorized　and　summarized,　and　their　advantages,　disadvantages,　effectiveness,　and　applicability　are　discussed.　Finally,　the　strategies　that　are　highly　effective　and　applicable　to　different　types　of　LMABs　are　highlighted　and　perspectives　for　further　investigation　of　corrosion　are　proposed.　©　2025　Elsevier　Inc.
