NEI Product Update for Solid Electrolyte Powder – NANOMYTE® SSE-10 (Li10SnP2S12)

October 22, 2013

Somerset, New Jersey – NEI Corporation announced today that over the past five months since the product launch of NANOMYTE® SSE-10, it has further enhanced the ionic conductivity of the solid electrolyte powder by an order of magnitude higher at room temperature. The ionic conductivity at room temperature, in a compact pellet form, is 12 mS/cm (Conductivity vs. T). The ionic conductivity is similar to that of a liquid electrolyte, but the use of a solid state electrolyte, such as SSE-10, eliminates the flammability issue associated with currently used liquid electrolytes. The updated materials specification sheet for SSE-10 can be found here.

On May 14th, 2013, NEI Corporation had announced that the patent pending new material, Lithium-Tin-Phosphorous-Sulfide (Li10SnP2S12 or LSPS), was available for sale in powder form. LSPS belongs to a family of “superionic” solids which conduct lithium-ions at room temperature. 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 plagued by the lack of widespread availability of these difficult-to-produce materials. NEI has utilized its extensive background in the synthesis of advanced materials to develop 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, our intent is to make it easy for Li-ion battery researchers to develop the next generation of all-solid-state Li-ion batteries,” said Dr. Ganesh Skandan, CEO of NEI Corporation. He added, “The NEI process is amenable to synthesizing variants of LSPS, such as compositional, morphology, and particle size changes.”
