摘要: Ultra-thin LiFePO4 platelets are prepared by a hydrothermal process using tetraethylene glycol as co-solvent. The have very thin thickness of about 50–80 nm, which is beneficial for Li ions to fast transfer in the bulk electrode. It found that as-synthesized cathode material exhibits quite high reversible capacity 137 mAh g−1 at 0.2 C. After carbon coating, obtained LiFePO4/C composite has enhanced electronic conductivity, and thus rate capability been improved significantly. At 8 12 C, discharge 104 95 mAh g−1, respectively, suggests ultra-thin promising candidate large-scale Li-ion batteries.
