ABSTRACT

Silicon-based materials have emerged as a highly promising alternative to conventional graphite anodes, owing to their high theoretical capacity and low cost. However, their practical application is significantly hindered by inherent challenges such as structural instabilities, poor reaction kinetics, and interfacial issues. Plasma technology, as a versatile processing tool, offers a unique and powerful platform for addressing these limitations. This review systematically summarizes existing research on the plasma-assisted preparation and modification of silicon-based anodes, with a particular focus on the pivotal role of plasma technology in material synthesis (nanostructure design and composites preparation) and structural chemistry engineering (crystal structure tailoring and surface/interface modification), as well as its influence on the electrochemical performance of the materials. These strategies have effectively addressed the critical issues associated with silicon-based anodes and led to remarkable improvements in their electrochemical performance. A systematic summary and in-depth understanding of this field are expected to pave the way for further optimization of silicon-based anode design and advance the application of high-energy-density lithium-ion batteries.
