Ball Milling Time

Silicon material possesses the highest theoretic capacity (4200mAh/g, ten times of the capacity of commercialized carbon anode materials) of all known anode materials for lithium ion batteries and thus receives lots of attention to date. Silicon-containing composite electrode for lithium ion batteries was prepared by high-energy ball milling process. The microstructure and morphology of silicon electrode was investigated in detail. The effect of the structure transformation of the electrode by ball milling on the electrochemical behavior was systematically analyzed. Electrode precursors after a mediate ball milling time of 45min is beneficial to get a better cycling performance, due to the well distributed and less destroy of Carboxyl Methyl Cellulose (CMC). Weak lithium insertion into CMC occurs unavoidably in the charging-discharging process of the composite electrodes, which should be the main reason for the sudden disability of electrode. The electrochemical properties can get a dramatic enhancement within voltage window of 0.02-1.5V. Excellent cyclability with high capacity retention above 1800mAh/g after 40 cycles could be gained by controlling the ball-milling time and the voltage windows. It might be a feasible way to obtain satisfactory cyclability for high capacity anode materials.

AbstractThis paper studies in-situ synthesis of Fe2O3/reduced graphene oxide (rGO) anode materials by different hydrothermal process.Scanning Electron Microscopy (SEM) analysis has found that different processes can control the morphology of graphene and Fe2O3. The morphologies of Fe2O3 prepared by the hydrothermal in-situ and oleic acid-assisted hydrothermal in-situ methods are mainly composed of fine spheres, while PVP assists The thermal in-situ law presents porous ellipsoids. Graphene exhibits typical folds and small lumps. X-ray diffraction analysis (XRD) analysis results show that Fe2O3/reduced graphene oxide (rGO) is generated in different ways. Also, the material has good crystallinity, and the crystal form of the iron oxide has not been changed after adding GO. It has been reduced, and a characteristic peak appears around 25°, indicating that a large amount of reduced graphene exists. The results of the electrochemical performance tests have found that the active materials prepared in different processes have different effects on the cycle performance of lithium ion batteries. By comprehensive comparison for these three processes, the electro-chemical performance of the Fe2O3/rGO prepared by the oleic acid-assisted hydrothermal method is best.
