Nature Communications, Published online: 22 May 2026; doi:10.1038/s41467-026-73484-4 Calcium metal batteries are limited by low reversibility and slow interfacial kinetics. Here, authors design an eccentric solvation structure by introducing monovalent cations and strongly coordinating organoborate anion, which enables fast desolvation and reversible calcium deposition.
