Synthesis of Nanocrystalline LiCd_xMn_2‐xO₄ Cathode Materials by Using a New Combustion Fuel for Li‐ion Polymer Battery

Abstract

Spinel LiMn₂O₄ possesses several advantages such as high voltage, wide operating temperature and long self‐life with much lower cost. However it suffers from loss of capacity during cycling. To improve the cycle performance of spinel LiMn₂O₄, Cd‐doped LiMn₂O₄ powders were synthesized by combustion route using gelatine as a new combustion fuel that acts as an excellent fuel as well as a very good dispersing agent to obtain nanocrystalline LiCd_xMn_2‐xO₄ powders. The structural phase identification and grain size of the synthesized LiCd_xMn_2‐xO₄ products were characterized by X‐ray diffraction studies and SEM analysis, respectively. Electrochemical discharge characteristics were performed by fabricating a button cell in the configuration of carbon/polymer electrolyte/LiCd_xMn_2‐xO₄.
