Synthesis and electrochemical properties of olivine LiFePO4 as a cathode material prepared by mechanical alloying

LiFePO4–Fe2P–C composite cathode: An environmentally friendly promising electrode material for lithium-ion battery

“…[10] A satisfactory long term cycling stability has been achieved through the formation of mesoporous LiFePO 4 /C nanocomposite (118 mAh g -1 at 10C after 1000 cycles) [2] and by creating LiFePO 4 /carbon composite (~ 85 mAh g -1 at 10C after 2400 cycles) via high-energy ball milling combined with spray-drying method. [11] Both of these reported results satisfy the long term cycling but their specific discharge capacity is not as high as we expect and thus, there is much more room for further improvement.…”

The Origin of the Residual Carbon in LiFePO4Synthesized by Wet Milling

“…[16][17][18] On the other hand, wet milled LiFePO4 delivered much improved initial capacity of 143 mAhg -1 at 0.2 C and this was comparable to the carbon-coated LiFePO 4 . [19][20][21] This suggests that the carbonaceous product produced on the particle surface during wet milling plays a similar role as the conductive layer from the conventional carbon coating LiFePO 4 . The initial capacity of LiFePO4 improved by carbon coating has been reported by others and they are compared in the Table 3.…”

Nanotechnology of Positive Electrodes for Li-Ion Batteries

“…This step aims at forming an intimate mixture of the reactants that effectively reduces the thermal treatment time and temperature, thus arresting the undesirable crystal growth. Some studies have highlighted the effectiveness of MA process for the synthesis of small and phase-pure particles of LiFePO 4 [21][22][23] and C-LiFePO 4 [24]. Even with a limited amount of carbon (2 wt %) appropriate for commercial batteries, the capacity of LiFePO 4 obtained after jet milling and wet milling reached 157 mAh·g −1 at 0.1C, 120 mAh·g −1 at 10C, without capacity fading after 60 cycles [21].…”
