Description
Summary:Highlights “Zero-strain” NiNb2O6 fibers with nanosized primary particles are explored as an all-climate anode material with comprehensively good Li+-storage properties. The almost completely opposite volume changes of electrochemical inactive NiO6 octahedra and active NbO6 octahedra are achieved through reversible O movement, leading to the “zero-strain” behavior of NiNb2O6 with minor unit-cell-volume change and excellent cyclability in a broad temperature range. The gained insight can provide guide for the exploration of high-performance energy-storage materials working at harsh temperatures.
