Abstract

Cobalt substitution for manganese sites in Na_0.44MnO₂ initiates a dynamic structural evolution process, yielding a composite cathode material comprising intergrown P2 and P3 phases. The novel P2/P3 composite cathode exhibits a reversible phase transition process during Na⁺ extraction/insertion, showcasing its attractive battery performance in sodium-ion batteries.
