烧结工艺对Li4Ti5O12改性材料电性能及综合性能影响
Effect of sintering process on electrical performance and comprehensive performance of Li4Ti5O12 modified material
摘要
Abstract
Li4Ti5O12 (LTO) anode material were modified with Mg2+ ion doping and carbon coating,and the effects of different sintering temperatures on electrical performance and comprehensive performance were studied.Also,the effects of different doping and sintering temperature on the structure and electrochemical performance of LTO were researched by XRD,SEM and cyclic voltammetry.The results show that 3％ Mg2+ ion doping LTO with 0.5％ inorganic carbon coating and 10％ organic carbon coating,material sintered at 800 ℃ for 12 h possesses excellent performance.Compared with the performance of pure-phased LTO,the electrochemical properties of modifying anode material are improved significantly.The initial capacity of modified material is 173 mAh/g and 104 mAh/g at 0.2 C and 10 C,respectively.关键词
