英文摘要	以间苯二酚甲醛树脂作碳源，由固相法合成LiMnPO4/C复合材料。研究不同合成温度和时间对产物形貌、结构以及电化学性能的影响。结果表明，600℃热处理3h制得的LiMnPO4粒径细小且分布均匀，一次颗粒为100~300nm，0.02C下首次放电容量达到121.6mAh•g-1，充放电循环20次仍然维持在110mAh•g-1以上，0.1C下放电容量为110mAh•g-1，1C仍然维持在60mAh•g-1以上。; The LiMnPO4/C composites were prepared using a solid-state reaction with addition of the resorcinol formaldehyde resin as the carbon source. The effects of reaction temperature and time on the crystal structure, morphology and electrochemical properties of the LiMnPO4/C composites were investigated. The results show that the best performance was achieved with the LiMnPO4/C composites synthesized at 600 oC for 12 h which had the particle sizes about 100~200 nm. The initial discharge capacities were 121.6 mAh?g-1 at 0.02C, 110 mAh?g-1 at 0.1C and more than 60 mAh?g-1 at 1C. An overall reversible capacity of 110 mAh?g-1 had been retained after 20 cycles.; 中央高校基本科研业务费专项资金 (DUT11NY08)、霍英东基金会; 作者联系地址：1. 大连理工大学，化工与环境生命学部，辽宁大连，116024 2. 广州市香港科大霍英东研究院，绿色产品及加工技术研究中心，广东广州，511458; Author's Address: 1.
