In this work, Li2Mn1–xCrxSiO4 cathode material was synthesized by the solid‐phase doping method and two‐step calcination. The appropriate calcination temperature can be obtained by TG‐DTA curve. XRD, SEM and TEM tests show that the prepared Li2Mn1–xCrxSiO4 has a Pmn21 space group structure, and the particle size decreases from 570 to 140 nm with the increase of the doped Cr content. Cr doping enhances...
