L-Lysine-assisted solvothermal synthesis of hollow-like structure LiFePO4/C powders as cathode materials for Li-ion batteries

LiFePO4/C powders were synthesized by solvothermal method using L-Lysine as a surfactant for controlling over the particle size and shape. The effects of L-Lysine contents on the phase, structure, microstructure, and electrochemical properties were studied by X-ray diffractometry, scanning electron...
