The cathode materials for a lithium-ion battery LiNi_1-xMn_xO₂ were prepared by a phase transfer method. XRD, SEM, IR, CV and charging-discharging experiments showed that when n(Li):n(Ni):n(Mn) was 1.24:0.9:0.1, and the intermediate gel powders were heated at 400℃ for 2 h, followed by sintering at 720℃ for 24 h, the redox reversibility of the electrode material was significantly improved; its activity was increased with stead working potential and its first discharging capability achieved 161.8 mA·h/g.
