Title: Framework Doping of Ni Enhances Pseudocapacitive Na-Ion Storage of (Ni)MnO 2 Layered Birnessite

Abstract

We report a (Ni)MnO 2 layered birnessite material with a framwork doping of Ni ions as the cathode for much enhanced aqueous Na-ion storage. Characterized by neutron total scattering and pair distribution function (PDF) analysis, in situ XRD, in situ X-ray PDF, XANES, and XPS, the synergistic interaction between disordered [NiO 6] and ordered [MnO 6] octahedra contribute to the enhanced specific capacity and cycle life (63 mAh g –1 at 0.2 A g –1 after 2000 full-cell cycles). Electro-kinetic analysis and structural characterizations show that stable local structure is maintained by [MO 6] octahedra during charge–discharge processes, while disordered [NiO 6] octahedra significantly improve pseudocapacitive redox charge storage. As a result, this finding may pave a new way for designing a new type of low-cost and high performance layered electrode materials.
