The transformation of amorphous red phosphorus into orthorhombic black phosphorus is demonstrated by a simple method. The method uses a high-energy mechanical milling technique at ambient temperature and pressure. Modification with carbon produces a composite that shows enhanced electrochemical discharge/charge behavior when used as an anode material for lithium-ion rechargeable batteries.
