Lithium Tin Phosphorous Sulfide (LSPS)

Lithium tin phosphorous sulfide (Li10SnP2S12, also referred to as LSPS) is a “superionic” solid that conducts lithium-ions at room temperature and can potentially replace conventional organic electrolytes, which are flammable and toxic. In addition to drastically improving the safety of the battery, solid state electrolytes allow the use of lithium metal as the anode material. This in turn increases the cell voltage and thereby increases the energy density of the battery.

NANOMYTE® SSE-10

NEI’s patent-pending, solid electrolyte material is designed to eliminate flammability issues associated with currently used liquid electrolytes, while providing high Li-ion conductivity (10-4 to 10-2 S/cm @ RT). NANOMYTE® SSE-10 is moisture sensitive and therefore produced and stored under inert conditions. The manufacturing process is also amenable to synthesizing variants of LSPS, which allows us to incorporate changes in composition, morphology, and particle size. Additionally, we can custom produce various solid electrolyte materials of both oxide and sulfide-based compositions.
