Abstract
A manufacturing method of electrode structure including phosphorus-hyperdoped silicon nanowires and electrode structure thereof are disclosed. The use of red P nanoparticles as a P precursor to synthesize phosphorus-hyperdoped silicon nanowires by the supercritical fluid method. In addition, the bilayer fabric electrode, which is composed of phosphorus-hyperdoped silicon nanowires and carbon nanotubes, to increase the contact of electrolyte and current collectors without the use of conductive additives and binders, is manufactured. The phosphorus-hyperdoped silicon nanowires/carbon nanotubes bilayer fabric electrode shows that the solution-grown phosphorus-hyperdoped silicon nanowires provides high cycle stability and fast charge-discharge capability, which is potential for applications on lithium-ion batteries.
