| 英文摘要 | The exploration of cathode materials with high capacity and power, fast charge/discharge rate, long lifespan and broad temperature adaptability is a challenge for the practical application of lithium ion batteries. here, submicro-sheet li3v2(po4)(3)/c (lvp/c) cathode materials have been successfully synthesized via a simple and universal phase-change method. this designed melting process increases the crystallinity and decreases the li+ diffusion distance, which effectively enhances the cycling stability and rate performances of the lvp/c cathode materials. the lvp/c cathode materials exhibit high discharge specific capacity of 130 mah g(-1) in the first cycle. the capacity retention is almost 100% after 100 cycles. in addition, at 10 c, more than 80% of initial discharge capacity is retained after 800 cycles, indicating excellent cycle performance at high rate. moreover, the synthesized lvp/c materials perform excellent low-temperature properties. at -20 degrees c, the specific capacity can reach 105 mah g(-1) at 0.5 c. this study provides a novel template-free synthesis method for nano/micro materials.
