Stabilized Lithium Metal Powder (SLMP®) - Performance Improvement of Silicon Based Anodes

Introduction Stabilized Lithium Metal Powder (SLMP) Technology developed by FMC Lithium provides an independent source of lithium for increasing the energy density of lithium ion batteries along with enhancement of calendar life performance. (1) Normal lithium metal powder is pyrophoric and can only be handled under heavy organic oils or in an inert atmosphere. SLMP has a continuous stabilizing coating layer which renders the powder non-pyrophoric and safe to handle under controlled environmental conditions such as in a dry room of -30 deg C dew point or better. SLMP contains about 98% metallic lithium and is being shipped by air or sea.
