Sustainable Synthesis of Nanorod Li2moo4 Anode Material Via Water Vapor-Assisted Solid-State Reaction for High-Performance Lithium-Ion Batteries

Abstract

Solid-state reaction (SSR) approach is widely used to create active materials for lithium-ion batteries (LIBs), but it has several disadvantages, such as irregular particle formation, high energy consumption, and environmental issues. In order to create Li2MoO4 (LMO), an anode material for LIBs, this study offers a more ecologically friendly technique: the water vapor-assisted acid-base reaction (ABR) synthesis method. Energy usage and synthesis time are greatly reduced by the ABR technique, which uses very little water and runs at a low temperature of 80 °C. The LMO particles Li-ion conduction pathways are improved by the formation of hexagonal nanorods from 500 nm-sized particles produced by this technique. Higher ion conductivity and a greater diffusion coefficient are shown by the ABR-synthesized LMO in comparison to the SSR sample. After 500 cycles of long-term charge-discharge testing, the battery demonstrated a consistent high-capacity performance of 216.83 mA h g–1, including an extraordinary 363.41 mA h g–1 at a high current density of 800 mA g–1. By providing a more effective and sustainable synthesis process for high-performance LIBs, the ABR method's more effective electrochemical characteristics indicate that it may be used in several types of active materials.
