A zero-strain insertion cathode material of nickel ferricyanide for sodium-ion batteries†
Abstract
Nickel ferricyanide is demonstrated as a zero-strain insertion cathode material for room-temperature sodium-ion batteries that can effectively accommodate volume variation during Na+ insertion/extraction. Given its highly stable structure, nickel ferricyanide shows impressive cycling performance and Coulombic efficiency.
