Advantages and disadvantages of these materials serving as positive electrodes in lithium ion batteries were elaborated. Nano-scale cathode materials were classified into lithium-inserted compounds, transition metal oxides, metal sulfides, and the other nano-cathode materials. Syntheses of these different nano-materials were summarized. Relationships between the preparation methods and the structure, morphology and electrochemical properties of the target nano-materials were discussed. Prospects of the nano-scale cathode materials for lithium ion batteries were predicted.
