柠檬酸络合法合成锂离子电池正极材料Li1+xMn2O4
Preparation of Li1+xMn2O4 for Lithium ion Battery by Citric Acid Complexation Method
【Abstract】 The cathode material Li 1+ x Mn 2O 4 was prepared by a modified citric acid complexation method. The influences of temperature, sintering time and n (Li)/ n (Mn) ratio on the structure of the products have been explored, characterized and tested by XRD, TEM, BET measurements. The sample sintered at 750 ℃ for 12 h had greater charge/discharge capacity, better cyclic stability under electric current charge/discharge cycle. The initial capacity reached 120 mA·h/g with the charge/discharge efficieney of 98% and maintained 115 mA·h/g after 50 cycles.Preparation
