MoS2 nanoclusters/graphene composite (MoS2/GNs) was prepared by one-step hydrothermal strategy in which MoS2 nanoclusters were enwrapped by graphene nanosheets. MoS2/GNs electrode delivered discharge/charge capacities of 890 and 885 mA · h/g at 0.2 °C (200 mA g–1) after 300 cycles, as rechargeable Li ion batteries (LIBs) anode material, corresponding to a reversible charge capacity retention of up to 73.0%. When the current was adjusted to 5 C (5000 mA g–1), the material could still deliver discharge/charge capacities of 612 and 591 mA · h/g. The synergistic effects between MoS2 and graphene contributed to excellent electrochemical performance, which efficiently improved its electrical conductivity, and concurrently inhibited volume change of the MoS2 in the electrode.

Al2O3-coated LiNi1/3Co1/3Mn1/3O2 powders with excellent electrochemical performance have been synthesized. The electrochemical performance of Al2O3-coated LiNi1/3Co1/3Mn1/3O2 electrodes has been studied as function of the level of Al2O3 coating. Coated LiNi1/3Co1/3Mn1/3O2 samples shows higher discharge capacity and better capacity retention than the base one. Among the coated samples, 1.0mol% coated sample exhibits the best electrical performance. It presents an initial discharge capacity of 174.5 mAh g-1 over 2.5~4.4V, and 84.7% capacity retention after 30 cycles over 2.5~4.6V.
