is considered as a next generation lithiumion battery (LIB) cathode material worth studying on account of its outstanding features. However, it is held back by poor cycling performance originated from the structure instability and side reactions. Here, spinel LNMO is decorated homogeneously via a facile hydrolysis and adsorption of γ-methyl-propylene trimethoxysilane (KH570), followed by thermal treatment at 750 °C, to bring a SiO 2 modification shell at the surface of LNMO and realize the ion doping of Si. The sintering process also brings more Mn 3+ in LNMO. However, only a moderate increase of Mn 3+ in LNMO can enhance the conductivity of ions and electrons, benefiting the enhancement of rate performance. The 0.8%-SiO 2 @LNMO cathode exhibits a high reversible capacity of 129 mAh g −1 , retaining a great capacity retention of 88% after 800 cycles at 1 C and 89.7% after 1000 cycles at 3 C. Meanwhile, a superior rate capability (90 mAh g −1 at 5 C) is achieved by applying the galvanostatic charge/discharge test.
