ABSTRACTLi2FeP2O7 is a newly developed polyanionic cathode material for high performance lithium ion batteries. It is considered very attractive due to its large specific capacity, good thermal and chemical stability, and environmental benignity. However, the application of Li2FeP2O7 is limited by its low ionic and electronic conductivities. To overcome the above problem, a solution-based technique was successfully developed to synthesize Li2FeP2O7 powders with very fine and uniform particle size (< 1 μm), achieving much faster kinetics. The obtained Li2FeP2O7 powders were tested in lithium ion batteries by measurements of cyclic voltammetry, electrochemical impedance spectroscopy and galvanostatic charge/discharge cycling. We found that the modified Li2FeP2O7 cathode could maintain a relatively high capacity even at fast discharge rates.

Aluminium has shown its superiority in stabilization of the monoclinic VO2(B) in free-standing nanobelts. In this paper, aluminium-doped VO2(B) nanobelts are successfully fabricated by a facile one-step hydrothermal method and used as cathode for lithium-ion battery. XPS results show that Al-doping promotes the formation of high valence state of vanadium in VO2(B) nanobelts. Due to the accommodation of valence state of vanadium and lattice volume, Al-doped VO2(B) nanobelts used as the cathode material for lithium-ion batteries exhibit better lithium storage properties with high capacity of 172[Formula: see text]mAh[Formula: see text]g[Formula: see text] and cycling stability than undoped VO2(B) nanobelts. This work demonstrates that the doping of aluminium can significantly enhance the electrochemical performance of VO2(B), suggesting that appropriate cationic doping is an efficient path to improve the electrochemical performance of electrode materials.
