Nature Communications, Published online: 05 May 2026; doi:10.1038/s41467-026-72848-0 Dead metal severely inhibited the development of alkali metal batteries. Here, authors reactivated dead Na by a reverse-pulse-interspersed charging strategy, which enhanced the rate and cycle capabilities of anode-free battery, and showed wide applicability to various alkali metal batteries.
