| Popis: | MoO3 is passionately examined as anode materials for lithium-ion batteries (LIBs), because of its exclusive interest due to high theoretical capacity (1117 mAhg−1). This article reports the synthesis of MoO3 nanoparticles by a simple solution combustion method using tamarind seed powder as a novel fuel where it produces in situ excess carbon by which it can eliminate the addition of acetylene black during the preparation of electrodes for LIB as a conducting material. The prepared MoO3 nanoparticles were characterized by XRD for structural analysis, vibrational bonding's through FTIR, CHN elemental analysis, BET for pore size distribution and specific surface area, morphology by SEM and TEM. Presence of carbon content in MoO3 nanoparticles show an excellent electrochemical performance by showing initial discharge capacity of 1171 mAhg−1 and stabilized to 162 mAhg−1 after 200 cycles and Columbic efficiency close to 100%. |
