This template explains and demonstrates how to prepare your camera-ready paper for Trans Tech Publications. The best is to read these instructions and follow the outline of this text. Common and cheap organic matters (Glucose anhydrous, Citric acid, Vitamin C, Sucrose) were selected for carbon coatings on LiFePO4. The four pre-treatment processes were employed to optimize the carbon coating process, and through solid state-carbothermal reduction synthesis of LiFePO4/C composites. The structure, morphology and electrochemical performance of the material were studied by XRD, SEM and galvanostatic charge-discharge methods. It is observed that the tap density of citric acid coating material can reach 1.44 g/ml. Conductivity increased four orders of magnitude. At room temperature, the initial discharge specific capacity of the materials is as high as 89.6 mAh/g at 5.0 C (corresponding to 850 mA/g). After 30 cycles, the capacity is 83.9 mAh/g and decay only 2.0 %.
