TI  - EFFECTS OF CALCINATION TEMPERATURES ON SYNTHESIS OF LiMn2O4
BY POLYMER MATRIX-BASED ALKALINE DEPOSITION METHOD
AV  - public
N2  - LiMn2O4 offers more affordable price than other cathode materials for lithium ion
batteries. The other factors are the abundance of the Mn element in nature and its low
level of toxicity. Therefore, this study aims to investigate the effects of calcination
temperature on the synthesis of LiMn2O4to obtain better condition for calcination to
produce LiMn2O4. In this study, cubic LiMn2O4 is synthesized by Polymer Matrix
Deposition Method using hydrothermal technique. Precursors used were LiOH, ethylene
glycol and Mn(CH3COO)2. The precursors were synthesized at 150oC for 6 hours and
calcined for 4 hours in different temperature variations in order to produce crystals with
different sizes and crystalinity. The interval calcination temperature is 500-900oC. The
compound was characterized by XRD, TEM and then was analyzed by U-Fit program. It
is found that at low calcination temperatures, impurities MnO2 is present but it decreases
along with the increase of calcination temperature. The lattice parameters and volume of
LiMn2O4also increase with the increase in heating temperature.The optimum calcination
temperature is 700oC.
