High purity black phosphorus powder (CAS number 7723-14-0), in the form of needle or sheet-like small sized crystals, is prepared from chemical vapor distribution. With theoretical specific capacity being approximately seven times larger than that of graphite as a negative material for batteries, exfoliated black phosphorus powders or their composite materials can significantly improve the performance of energy storage devices.

Black phosphorus powder is generally used to prepare black phosphorus quantum-dots (BPQDs) and nano-platelets by liquid-exfoliation (assisted by sonication). As a result of its high purity, the powdered form can also be used in chemical vapour deposition to create high-quality, atomically thin films.
