Electrolyte Materials for All Solid State Batteries
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. Solid electrolytes conduct lithium ions at room temperature and can potentially replace conventional organic electrolytes, which are flammable and toxic, thereby drastically improving the safety of batteries. NEI is actively involved in producing different solid electrolyte materials of both oxide and sulfide based compositions, as well as polymer based electrolyte materials.

- Instructions for Mixing (In Glove Box Only)
When mixing with SSE-10 LSPS powder (or similar sulfide), mixing and tape casting must be done in the glovebox. Even when dispersed, the sulfide material is sensitive to moisture and oxygen and can generate H2S gasses. Ionic conductivity will be lost if exposed to humidity. Handle materials in a glove box, under inert gas, at all times.
- In a bottle, combine (by weight): 3 parts SSE-20 dispersion fluid per 1 part solid electrolyte powder.
- Add a magnetic stir bar to the bottle, and close the cap.
- Place the bottle on a magnetic stirrer plate and stir for a few minutes until the powder is all wet. Allow the powder and solvent to continue mixing until uniformly dispersed (make sure no dry powder is stuck on the side of the bottle).
- Remove the stir bar and ensure the dispersion is uniform before casting the tape.
- Guidelines for Electrode Tape Fabrication (In Glove Box Only)
- Surface Preparation :
The current collector surface must be clean, dry, and in sound condition. Before casting the dispersion, remove all oil, grease, dust, dirt and other foreign material by using a solvent such as acetone, and wipe the surface. - Tape Casting :
The preferred tool for tape casting is doctor blade. Dry tape at room temperature (25 C) – drying times will vary, depending on environmental conditions.

Storage & Handling
- Storage and Handling
- Precautions for Safe Handling
Appropriate personal protective equipment should be used at all times. Avoid contact with eyes and skin. Provide good ventilation or extraction, and avoid breathing vapors. - Conditions for Safe Storage
Keep container tightly closed in a dry and well-ventilated place. Containers which are opened must be carefully resealed and kept upright to prevent leakage. Heat sensitive. Store under inert gas. Storage class (TRGS 510): Non-combustible, acute toxic Category 3 / toxic hazardous materials or hazardous materials causing chronic effects.
Hazardous Shipping Restrictions : Due to restrictions regarding dangerous goods shipping regulations, this material must be shipped separately from other hazardous (“dangerous when wet”) sulfide-based materials.
