The dual modification strategy proposes a novel approach that can accelerate commercialization by simultaneously alleviating the surface instability and bulk structural degradation of Ni-rich cathode materials for state-of-the-art LIBs. In addition, Sn-modified NCM811 cathode shows an improved reversible capacity of 144.9 mAh g −1 and excellent electrode kinetics after 200 cycles. The electrochemical results deliver that the Sn dual-modified NCM exhibits the highest discharge capacity of 86.5% at 6.0 C and superior initial discharge capacity of 177.8 mAh g −1. Herein, we demonstrated an interfacial/surface dual modification strategy, one of the most important techniques for fabricating LiNi 0.8Co 0.1Mn 0.1O 2, NCM cathode materials via Li 2SnO 3 surface coating and Sn 4+ gradient doping. Nevertheless, intrinsic structural/chemical instability and unwanted side reactions on the surface during charge/discharge, leading to rapid capacity fading and inferior cycle performance, severely impeded its commercialization. Ni-rich ternary oxide cathode (LiNi 0.8Co 0.1Mn 0.1O 2, NCM) is highly promising candidate for lithium-ion batteries (LIBs) due to its relatively large specific capacity and high energy density.
