| 英文摘要 | Mesoporous lifepo4/c microsphere was successfully prepared by spray drying assisted template method (sdatm) with citric acid as a template. this material has an average pore size of 50 nm and gives large specific surface area (32.2 m(2) g(-1)) with evenly distributed carbon (4.3 wt.%). it is also easy to bring into contact with electrolyte, facilitate the electric and lithium ion diffusion. it presents large reversible capacity of 158.8 mah g(-1) at c/10, even high rate capacity of 59.7 mah g(-1) at 20c, and excellent capacity retention rate closed to 95.5% after various current densities.
