MgHPO4 has been introduced as a reactant that interacts with LiNi0.6Co0.2Mn0.2O2 (NCM622) to achieve the dual modification of Mg2+ gradient doping and Li3PO4 surface coating. The structure, morphology, elemental distribution,...
Novel hierarchical ball-in-ball hollow Li-rich microspheres with a multi-elemental composition are reported as a high performance cathode material for Li-ion batteries with excellent rate capability and superior cycle stability.
