Vacancy defective perovskite Na0.85Ni0.45Co0.55F3.56 nanocrystal anodes for advanced lithium-ion storage driven by surface conversion and insertion hybrid mechanisms†
Abstract
A vacancy defective perovskite Na0.85Ni0.45Co0.55F3.56 nanocrystal (NNCF) has been introduced as an advanced anode for Li-ion capacitors (LICs), Li-ion batteries (LIBs) and Li-dual-ion batteries (Li-DIBs), exhibiting the surface conversion and insertion hybrid mechanisms for Li-ion storage.
