The prepared LiFePO4 platelets have a very thin thickness of about 50-80 nm, which is beneficial for Li ions to fast transfer in the bulk of the electrode. It is found that the as-synthesized LiFePO4 cathode material exhibits a quite high reversible capacity of 137 mAh g-1 at 0.2 C. After carbon coating, the obtained LiFePO4/C composite cathode has the enhanced electronic conductivity, and thus the rate capability has been improved significantly. At 8 and 12 C, the composite has the discharge capacity of 104 and 95 mAh g -1 , respectively, which suggests that the ultra-thin LiFePO 4 platelets are a promising candidate for the large-scale Li-ion batteries. © Springer Science+Business Media, LLC 2011.||Source Title:||Journal of Materials Science||URI:||http://scholarbank.nus.edu.sg/handle/10635/93996||ISSN:||00222461||DOI:||10.1007/s10853-011-5403-1|
