In this work, a simple way was contrived to enhance the rate capability and cycle life of LiNixMnyCo(1-x-y)O2 by doping Zr into the material. Zr-doped LiNixMnyCo(1-x-y)O2 was synthesized by solution-based synthetic route, and its electrochemical performance was investigated as 2016 coin-type half cell. With doping, some impurity peaks appeared in the XRD pattern, which seems to
be related to Zr containing oxides. The enhanced characteristics in the rate capability and cycle life might be the result of the protective effect of Zr oxide against the decomposition of electrolyte and a faster Li diffusion rate.
Magnetic Fe3O4 particles are used as the binder in a Li-ion battery. This new battery gives a long cycle life and can work well even after intensive vibration. The electrode is fabricated in a liquid-free process and can be easily recycled after battery disposal. It decrease the total cost and pollutant emission over the whole battery life.
An SnO2-carbon nanocomposite was created by a self-assembly method. This showed promising electrochemical performance as both a Na and Li ion battery anode, with among the best cyclability and rate capability when tested against Na.
A nanocomposite of core@shell Sb@Sb2O3 particles anchored on 3D porous nitrogen-doped carbon nanosheets is synthesized and employed as a anode for Li-ion battery, demonstrating excellent rate capability and cycle performance.
