Mesoporous MnMoO₄ Nanorods for Enhanced Electrochemical Performance

Abstract

High energy demand has directed the present‐day research towards synthesis and applications of heterostructured nanomaterials such as molybdenum oxysalts over mono‐structured nanomaterials. Molybdenum oxysalt is a promising anode material for lithium ion batteries because of its high theoretical lithium storage capacity (998 mAh g−1) and flexible composition. Engineering the morphology and porosity of a material has proven to be a productive approach towards enhancing its performances. Here in, we have demonstrated a one pot synthesis of mesoporous MnMoO4 nanorods and its enhanced electrochemical performance for Li‐ion battery anode. Several physiochemical techniques have been used to validate the desired properties and purity of the synthesized material. It exhibits high lithiation capacity of 1050 mAh g−1 and stability over 100 cycles at 0.5 C. The enhanced performance is attributed to its structural stability and mesoporous nature.

Unraveling the MnMoO4 polymorphism: a comprehensive DFT investigation of α, β, and ω phases

“…The results for lattice parameters of MnMoO 4 polymorphs obtained by our simulations agree with experimental data at room conditions [ 24 , 27 , 28 , 48 , 49 ] and other theoretical calculations [ 2 ]. Meanwhile, there were not reported data for bond lengths and distortion degree in the literature for evaluated polymorphs.…”
