NEI Corporation is making Li10SnP2S12 (Lithium-Tin-Phosphorous-Sulfide, LSPS) available for sale in powder form. LSPS belongs to a family of superionic solids which conduct lithium-ions at room temperature.
Commercial Lithium-ion batteries usually contain an electrolyte that is dissolved in flammable solvents. The use of a solid state electrolyte, such as LSPS, will eliminate the flammability issue associated with currently used liquid electrolytes.
Sulfide compounds with high Li-ion conductivity are not commonly available, and as such, the development of solid state electrolyte–based Li-ion batteries has been hampered by the lack of widespread availability of these difficult-to-produce materials.
NEI developed a process for producing sulfide materials in a form that allows them to be used in Li-ion cells.
By making solid state electrolyte powders readily available in test quantities, our intent is to make it easy for Li- ion battery researchers to develop the next generation of all-solid-state Li-ion batteries. The NEI process is amenable to synthesizing variants of LSPS, such as compositional changes.—Dr. Ganesh Skandan, CEO of NEI Corporation
