摘要: Abstract Lithium-manganese dicarboxylates were prepared as a precursor for the synthesis of LiMn 2 O 4 spinel. The structure and thermal decomposition investigated by means DTA-TG-MAS, XRD, FTIR measurements. results indicated that malonate tartrate form mixture lithium-manganese complex salt managanese salt, but oxalate succinate have chain-like in which lithium manganese ions are linked dicarboxylic acid ion. For all dicarboxylates, there is no growth crystalline intermediates during their process. Beacuse its low temperature, 260°C, was most suitable preparation
