英文摘要	采用球磨微波法合成锂离子电池正极材料Li3V2(PO4)3/C，并研究了微波辐射时间对样品电化学性能的影响. 结果表明，640 W微波辐射18 min合成的材料，其结晶度高、粒径小而均匀. 该电极5C倍率下首次放电比容量达101.3 mAh?g-1，300周期循环，其放电比容量仍保持100.8 mAh?g-1，展示出良好的应用前景.; The cathode materials of Li3V2(PO4)3/C were successfully synthesized by ball-milling assisted microwave method and the microwave irradiation time was also optimized. It is found that the Li3V2(PO4)3/C material obtained at a microwave power of 640 W for 18 min showed the best electrochemical performance with the initial reversible capacity of 101.3 mAh.g-1 and the remained 100.8 mAh.g-1 at 5C rate after 300 cycles. This excellent electrochemical capability may be resulted from good crystallinity, smaller and uniform particle size of the material, showing a great promise for battery applications.; 国家自然科学基金(No.20973124)和广东省重大科技专项（No.2009A080208001）资助; 作者联系地址：1. 天津大学化工学院，天津 300072；2. 迈科科技有限公司，广东东莞 523800; Author's Address: 1.
