“…Shorter diffusion length of Li ? through the nanosized LiFePO 4 [16] and the high crystallinity may result in the good cycling properties by retarding dissolution of iron from the cathode material [44]. Figure 5 shows the discharge capacities versus cycle number plots for MO/Li (Co 3 O 4 , CuO, NiO, MnO 2 , and Fe 2 O 3 ).…”

Nanosized lithium iron phosphate (LiFePO 4 ) and transition metal oxide (MO, where M is Cu, Ni, Mn, Co, and Fe) particles are synthesized continuously in supercritical water at 25-30 MPa and 400°C under various conditions for active material application in lithium secondary ion batteries. The properties of the nanoparticles, including crystallinity, particle size, surface area, and electrochemical performance, are characterized in detail. The discharge capacity of LiFePO 4 was enhanced up to 140 mAh/g using a simple carbon coating method. The LiFePO 4 particles prepared using supercritical hydrothermal synthesis (SHS) deliver the reversible and stable capacity at a current density of 0.1 C rate during ten cycles. The initial discharge capacity of the MO is in the range of 800-1,100 mAh/g, values much higher than that of graphite. However, rapid capacity fading is observed after the first few cycles. The continuous SHS can be a promising method to produce nanosized cathode and anode materials.Keywords Lithium iron phosphate Á Metal oxide Á Cathode-active material Á Anode-active material Á Supercritical hydrothermal synthesis Á Lithium secondary battery

“…Lithium iron phosphate (LiFePO 4 ) as a very promising active material attracts much attention for electrical vehicles because of its low toxicity, high safety, potentially low cost, excellent life cycle, high structural stability, and large theoretical capacity (170 mA h g À1 ), among others [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. However, the kinetic performance of LiFePO 4 suffers significantly from poor electronic conductivity and slow lithium-ion transport.…”

Lithium iron phosphate with the structure of olivine has many advantages: low price, environmentally friendly, great thermal stability and excellent cycle performance when used as the anode materials, making it one of the most promising anode materials. In this article, we used the precusor FePO 4 pre-prepared to produce LiFePO 4 and the performances were tested. The process of preparation of the precusor FePO 4 were optimized and the reaction mechanism was probed into. The precusor FePO 4 was prepared by the raw materials as follows: ferric nitrate, phosphoric acid and diammonium hydrogen phosphate, the temperature, PH, Fe/P and the time of reaction were considered. LiFePO 4 was prepared by calcining the mixture of iron phosphate, lithium carbonate and glucose after mixed. The test of charge-discharge indicates that the sample of LiFePO 4 holds the discharging voltage platform 3.4 V, the first charge-discharge specific capacity under 0.1C are 164.6 and 163.6 mAh/g respectively.
