Synthesis and characterization of novel cathode material Li3V2(PO4)3 by carbon-thermal reduction method ZHONG Sheng-kui(钟胜奎)1,2, YIN Zhou-lan(尹周澜)1, WANG Zhi-xing(王志兴)3; GUO Hua-jun(郭华军)3, LI Xin... was prepared by a carbon-thermal reduction (CTR) process. V2O5, LiOH?H2O, NH4H2PO4 and C were used as starting materials to synthesize Li3V2(PO4)3 by sintering the mixture at 800 ℃ for 24 h. The property......
on a carbon-thermal reduction (CTR) process. Firstly, V2O5, NH4H2PO4 and acetylene black are reacted under an Ar atmosphere to yield VPO4. The transition-metal reduction is facilitated by the CTR based on C→CO...+), and the capacity retains 89 mA?h/g after 30 cycles. Key words: lithium ion batteries; cathode material; LiVPO4F; carbon-thermal reduction method ......

J. Cent. South Univ. (2016) 23: 1318-1325 DOI: 10.1007/s11771-016-3182-1 Reduction mechanism of Fe2O3-Cr2O3-NiO system by carbon ZHANG Yan-ling(张延玲), GUO Wen-ming(郭文明), LIU Yang(刘洋), JIA Xin-lei(贾昕磊... of the reduction. Factors such as temperature, carbon content, sample size have a more significant effect during the final stage (α>38%). The metallic product formed at the initial stage (a Fe-Ni alloy) greatly......
