Synthesis of surface modified LiFePO4 cathode material via polyol technique for high rate lithium secondary battery
چکیده انگلیسی
The NiO-coated LiFePO4 composite cathode materials were prepared by simple tailored polyol technique, which has orthorhombic olivine structure without NiO phase. It delivers the reverse capacity of 164 mAh g−1 at 0.1 C at ambient temperature. The material exhibits stable reverse capacity for several cycles even for the higher C-rates. Increasing the rate, the reverse capacity is almost stable over several cycles. Furthermore, at a high rate viz., 10, 20 and 30 C, the discharge capacity has been observed for the optimized NiO-coated LFP as 135, 120 and 69 mAh g−1, which demonstrates the excellent rate performance that can be useful for high power lithium secondary battery.
