High Performance Battery Materials
Cathodes, Anodes, and Electrolytes
Solid electrolytes conduct 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. This in turn increases the cell voltage and thereby increases the energy density of the battery.
NEI is actively involved in producing different compositions of sulfide-based solid electrolyte materials – such as our own patent-pending Lithium Tin Phosphorus Sulfide (Li10SnP2S12) – as well as oxide, phosphate, and polymer-based electrolyte material compositions as well.
A long trusted source for custom developed materials used in lithium-ion batteries, NEI Corporation is your go-to source for commercial and custom solid electrolyte materials.
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), which have distinctive features such as high phase purity and crystallinity, fine particle size, and a high degree of particle size distribution (PSD) uniformity. The afore-mentioned powder characteristics allow NEI’s oxide-based solid electrolyte materials to be produced into suitable structures with excellent electrochemical properties.

Sulfide-based solid electrolytes are one of the most highly sought and promising candidates for all-solid-state batteries. 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 potentially allows them to be used in Li-ion cells.
