摘要：
Extending the working voltage is an effective approach to enhance the reversible capacity of LiNi1-x-yCoxMnyO2 layered oxide cathode materials. However, the layered Ni-rich LiNi0.8Co0.1Mn0.1O2 cathode suffers a severe structural instability and rapid capacity decrease during high-voltage cycling (4.6 V). In order to solve these problems, the surface coating layer of SnO2 is successfully prepared via a one-step synthesis way followed with a high temperature calcination method. The 1.0% SnO2-modified LiNi0.8Co0.1Mn0.1O2 delivers a much higher capacity retention (83.63%) compared with pristine sa...
