# metadata.dc.description.abstract[].value
The functionalization of molybdenum oxide (MoO3) nanoparticles is presented as a method to significantlyenhance the cycling stability of lithium-ion battery (LIB) anodes based on silicon nanowire (SiNW) arrays.Transition-metal oxides have emerged as promising candidates for advanced anode materials in modern Li-ion batteries. In this study, we explore a novel approach involving the deposition of MoO3 nanoparticles viaunique drop-casting technique onto pre-fabricated SiNW arrays, fabricated using a straightforward one-stepmetal-assisted chemical etching (MACE) process. The primary objective is to assess their potential suitabilityas anode materials for Li-ion batteries. Our methodology entails the top-down synthesis of binder-free hybridelectrodes, achieved by depositing Mo oxides nanostructures onto SiNW arrays through a combination of drop-casting and thermal annealing processes. The resulting MoO3@SiNWs hybrid structure exhibits distinctive and specialized attributes, including exceptional structural resilience, diminutive particle dimensions, and a porous configuration. These features effectively enhance electron and ion accessibility at the electrode-electrolyte interface.Electrochemical assessments reveal that the MoO3@SiNWs hybrids exhibit superior lithium storage perfor-mance compared to bare SiNW electrodes. Particularly under high current densities, MoO3 nanoparticlesdeposited via drop-casting technique demonstrate improved cycling stability and increased capacity. Theenhanced electrochemical characteristics are primarily ascribed to the synergistic effects between the MoO3nanoparticles and SiNW arrays. The findings of this study strongly suggest that the MoO3@SiNWs hybridstructure holds substantial promise as anode materials for high-performance energy storage devices.
