Electrochemical activity of ultrathin MoO3 nanoflakes for long cycle lithium ion batteries

Abstract

Solution based combustion method synthesis of porous MoO3 nanoparticles in one step by using ammonium heptamolybdate pentahydrate as a precursor with novel areca seed powder as green fuel. The analytical techniques like PXRD, FTIR, SEM, HRTEM, SAED were recorded in order to detect morphology, structure and composition of synthesised material. The obtained average crystalline size from XRD analysis was found to be 20 nm with TEM analysis of particle size ranging from 2 to 10 nm. As prepared material shows high specific capacity of 980 mAhg−1 and excellent run of about 400 cycles with extraordinary cycling performance of 652 mAhg−1 after 200 cycles including enhanced rate capability of 564mAhg−1 even at high current rate and thereby proving the auspicious anode material for lithium ion batteries.
