Surface phosphation of 3D mesoporous NiCo₂O₄ nanowire arrays as bifunctional anodes for lithium and sodium ion batteries.

ABSTRACT: A novel surface phosphate strategy was adopted to dramatically improve the charge transport, ion diffusion, electroactive sites, and cycle stability of mesoporous NiCo₂O₄ nanowire arrays (NWAs), drastically boosting their electrochemical properties. Consequently, the as-prepared phosphated NiCo₂O₄ NWA (P-NiCo₂O₄ NWA) electrode achieved excellent energy storage performance as a bifunctional anode material for both lithium ion batteries (LIBs) and sodium ion batteries (SIBs). When evaluated as an anode for LIBs, this P-NiCo₂O₄ NWA electrode showed a high reversible capacity up to 1156 mA h g^-1 for 1500 cycles at 200 mA g^-1 without appreciable capacity attenuation, while in SIBs, the
