Abstract

Spinel LiMn₂O₄ was prepared from CH₃COOLi·2H₂O,Mn(CH₃COO)₂ and adipic acid based on sol-gel process.XRD analysis showed that when the sintering temperature increased,the crystallinity increased,and the capacity also increased.However,its cycleability reached a maximum value at 750 ℃.The sintering duration also influenced on the capacity.The optimized performance was obtained when the sintering was carried out at 750 ℃ for 20 h.Under these conditions,as-prepared spinel LiMn₂O₄ presented the initial discharge capacity of 130 mAh·g^-1 and 125 mAh·g^-1 at 15^th cycle.
