J. Cent. South Univ. Technol. (2008) 15: 531-534 DOI: 10.1007/s11771-008-0100-1 Preparation of LiFePO4 for lithium ion battery using Fe2P2O7 as precursor HU Guo-rong(胡国荣), XIAO Zheng-wei(肖政伟.... The as-prepared Fe2P2O7 crystallizes in the space group and belongs to β-Fe2P2O7 for crystal phase. The particle size distribution of Fe2P2O7 observed by SEM is 0.4-3.0 μm. During the Li+ ion......
the substrate and the filter duct which was floated. The substrate was biased with a negative voltage or connected to anode, respectively. the parameters of the exited plasma and ion saturation current are examined by Langmuir probe and current collector plate. It was found that When the wire netting is connected to apositive voltage and the substrate is biased with a negative voltage, the ion saturation......
