Plasma spray physical vapor deposition (PS-PVD) is inherently a high throughput processing and its characteristic rapid condensation of high temperature vapor offers to produce Si nanoparticles from metallurgical grade Si powders that are feasible for the negative electrode of lithium ion batteries. Structuring the high-ordered nanocomposite Si particles is further anticipated by a control of co condensation of high temperature alloy vapor in a single continuous processing. The guiding principle of the nanocomposite particle formation in PS-PVD and their structural characteristics as well as the potential as the negative electrode of the lithium ion batteries are reviewed.
