Abstract

Novel layered Na_0.5Ni_0.25Mn_0.75O₂ micro-sheets were explored as cathode materials for Na-ion batteries for the first time, which can exhibit electrochemical activity operating at an average voltage of 3.8 V (vs. Na⁺/Na) and deliver a reversible discharge capacity of 121 mA h g⁻¹ at 0.2C rate.
