Your Go-to source for Solid Electrolyte Materials

NEI is actively involved in producing a variety of different compositions of sulfide, oxide, phosphate, and polymer-based electrolyte material compositions. We are a long trusted manufacturer of Specialty Materials and a go-to source for commercial and custom solid electrolytes for lithium batteries. All of our materials are made in-house & shipped directly to our customers.

Sulfide-based Solid Electrolytes

Sulfide-based solid electrolytes are one of the most highly sought and promising candidates for all-solid-state batteries. NEI has utilized its extensive background in the synthesis of advanced materials to develop a process for producing sulfide materials in a form that potentially allows them to be used in Li-ion cells.

  • NANOMYTE® SSE-10 – “LSPS,” Lithium Tin Phosphorus Sulfide (Li10SnP2S12), 3-5 µm
  • “LPS” – Lithium Phosphorus Sulfide (β-Li3PS4), 3-5 µm
  • “LPSCl” – Lithium Phosphorous Sulfur Chloride (Li6PS5Cl), 3-5 µm
  • “Fine LPSCl” – Lithium Phosphorous Sulfur Chloride (Li6PS5Cl), ~1 µm
  • “LPSClI” – Lithium Phosphorus Sulfur Chloride Iodide (Li6PS5Cl0.9I0.1), 3-5 µm

Oxide-based Solid Electrolytes

Inorganic oxide-based solid electrolytes are among the most sought-after candidates for an all-solid-state battery. NEI produces a variety of oxide-based solid electrolyte powders (garnet-type, NASICON-type, and perovskite-type), with distinctive features such as high phase purity and crystallinity, fine particle size, and a high degree of particle size distribution (PSD) uniformity. 

Phosphate-based Solid Electrolytes

NEI produces phosphate-based solid electrolyte powders with distinctive features, such as high phase purity and crystallinity, fine particle size, and a high degree of particle size distribution (PSD) uniformity. NEI can supply the following phosphate-based electrolytes:

Polymer & Hybrid Electrolytes

NEI provides solid polymer electrolytes for rechargeable solid-state lithium batteries. The electrolytes are based on specially synthesized polymers that are complexed with highly conductive lithium salts.
