“LPSClI” – Lithium Phosphorus Sulfur Chloride Iodide (Li6PS5Cl0.9I0.1)

Oxides

Oxide-based Solid Electrolytes

NEI produces various oxide-based compositions, such as:

“LLTO” – Lithium Lanthanum Titanate (Li_0.34La_0.56TiO₃)
“LLZO” – Al-doped Lithium Lanthanum Zirconium Oxide (Li_6.24La₃Zr₂Al_0.24O_11.98)
“LLZTO” – Ta-doped Lithium Lanthanum Zirconate (Li_6.2Al_0.2La₃Zr_1.8Ta_0.2O₁₂)
Coming Soon – Nb-doped and Ga-doped LLZO

Phosphates

Phosphate-based Solid Electrolytes

NEI produces high phase purity phosphate-based solid electrolyte powders, such as:

“LATP” – Lithium Aluminum Titanium Phosphate (Li_1.4Al_0.4Ti_1.6(PO₄)₃)
“LAGP” – Lithium Aluminum Germanium Phosphate (Li_1.5Al_0.5Ge_1.5(PO₄)₃)

Polymers

Polymer-based Solid Electrolytes

Our polymer electrolytes are complexed with highly conductive lithium salts and made exclusively by NEI:

NANOMYTE® H-Polymer – PEO-based co-polymer electrolyte
NANOMYTE® SE-50 – hybrid polymer-ceramic electrolyte

Halides

Halide-based Solid Electrolytes (New)

Halide solid electrolytes are a promising new type of material being investigated for use in all-solid-state batteries (ASSBs), due to their high ionic conductivity, electrochemical stability, and air stability.

“LICl” – Lithium Indium Chloride (Li₃InCl₆)

NASICON

Solid Electrolytes for Na-ion Batteries

Sodium Aluminum Titanium Phosphate is a NASICON material being explored as a potential solid electrolyte material for sodium-ion batteries (SIBs). NEI’s “NATP” is available in quantities of 50g or more.

“NATP” – Sodium Aluminum Titanium Phosphate (Na_1.3Al_0.3Ti_1.7P₃O₁₂)
