Abstract

Highly Li⁺-conductive HfNb₂₄O₆₂ is explored as a new intercalation-type niobium-based oxide anode material for superior Li⁺ storage. HfNb₂₄O₆₂ owns a Wadsley–Roth shear structure with a large unit-cell volume, leading to a large Li⁺ diffusion coefficient. HfNb₂₄O₆₂ shows a large capacity, safe operating potential, high rate performance and good cyclability.
