Tunable LiFePO4/C thin films demonstrating high power were fabricated by drop-casting a LiFePO4 nano-plate/sucrose suspension on titanium foil, followed by pyrolysis at 600°C for 3h in nitrogen. The thickness, carbon content, and morphology of the LiFePO4/C film cathode can be adjusted by changing the amount of drop-cast, sucrose solution concentration and LiFePO4 raw material. For this work, well-crystallized LiFePO4 nano-plates synthesized via solvothermal route were used to prepare high power LiFePO4/C thin films. The resultant binder-free films consisted of well-packed LiFePO4 nano-plates coated with nano-carbon, a result of sucrose pyrolysis, and were directly assembled into cells for testing. The LiFePO4/C nano-composite film cathode delivered a lithium ion intercalation capacity of 162mAhg−1 and 90mAhg−1 at current density of 170mAg−1 (1C) and 1.7Ag−1 (10C), respectively, while demonstrating excellent cyclic stability.
