“…Recent developments show the possibility of drastically increasing power densities [4]. The electrochemical performance of LiFePO 4 depends on various factors, like the method of preparation (hydro/ solvothermal [5,6], coprecipitation [7], gel combustion method [8], Spray-drying [9], micro wave synthesis [10], super critical method [11], other methods etc. [3]).…”

“…Also the surrounding Super P and a uniform amorphous carbon layer can lead to better electrochemical performance. Super P can acts as bridges, interconnecting the isolated Li 2 FeSiO 4 particle, and providing valid conductive network, the uniform amorphous carbon layer could effectively restrict the growth of the particles and increase the powder conductivity, therefore the electronic transport properties can be improved [15,45,48]. The results indicate that the synthesis method obtained the sample with spherical morphology and uniform carbon coating.…”

LiFePO 4 /C composite is synthesized by oxalic acid-assisted rheological phase method. Fe 2 O 3 and LiH 2 PO 4 are chosen as the starting materials, sucrose as carbon sources, and oxalic acid as the additive. The crystalline structure and morphology of the products are characterized by X-ray diffraction and field emission scanning electron microscopy. The charge-discharge kinetics of LiFePO 4 electrode is investigated using cyclic voltammetry and electrochemical impedance spectroscopy. It is found that the introduction of appropriate amount of oxalic acid leads to smaller particle sizes, more homogeneous size distribution, and some Fe 2 P produced in the final products, resulting in reduced polarization, impedance, and improved Li + ion diffusion coefficient. The best cell performance is delivered by the sample with R=1.5 (R of the molar ratio of oxalic acid to LiH 2 PO 4 ). Its discharge capacity is 154 mAh g −1 at 0.2 C rate and 120 mAh g −1 at 5.0 C rate. At the same time, it exhibits an excellent cycling stability; no obvious decrease even after 1,000 cycles at 1.0 C rate.
