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-10D (dispersion)Slurry Pour

NANOMYTE® SSE-10D is a 2-part, ready-to-disperse Li10SnP2S12 (SSE-10, or LSPS) solid electrolyte powder with compatible solvent. When mixed and dispersed, the material is ready to cast into flexible tapes, providing more options for cell designers to combine with suitable cathode and anode active materials. 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 – 10-3 S/cm @ RT).


  • Ionic Conductivity: 10-4 – 10-3 S/cm
  • Final Solids Content: 20 – 25 wt%
  • Secondary particle Size: 7 – 8 μm
  • Detailed specifications »

NANOMYTE® SSE-10D is available for purchase in lots of 20g, 40g, 100g, and 400g (total weight with solvent). SSE-10D can also be supplied in customized formulations, with the addition of an active material (such as LCO, LFP, NCA, LMNO, graphite, and LTO).

LSPS is also available in powder form.
