Custom Materials Solutions
As a world leading developer and manufacturer of commercial and specialty materials for Lithium-ion and Sodium-ion batteries, NEI Corporation is well positioned to reproducibly synthesize small and large quantities of custom solid electrolyte compositions. The company specializes in custom sythesizing hard to obtain compositions, as well as developing new compositions and particle morphologies, including nanoscale particle engineering. We employ a scalable and economical solid-state synthesis process to produce battery materials with precise control over composition and particle structure. NEI works diligently with both battery developers and manufacturers to produce solid electrolyte materials for that are ideally suited for their application.
NEI’s Capabilities
Solid Electrolyte Materials
Researchers are actively exploring all-solid-state batteries, composite electrolytes, new materials, and interface engineering to improve the performance and safety of solid electrolyte-based batteries. The search for novel solid electrolyte materials continues, with a focus on materials that offer high ionic conductivity, wide electrochemical window, and compatibility with various electrode materials.
NEI is actively involved in producing various compositions of solid electrolyte materials, such as:
- Sulfide-based Solid Electrolytes – including LPS, LSPS, LPSCl (& its variants)
- Oxide-based Solid Electrolytes – including LLTO, LLZO, & doped variants of LLZO
- Halide-based Solid Electrolytes – *new* Lithium Indium Chloride (Li3InCl6)
- Polymer-based Solid Electrolytes – PEO-based (H-polymer) & polymer-ceramic composite (SE-50)
- Phosphate-based Solid Electrolytes – including LATP and LAGP
- Sodium-ion Solid Electrolytes – “NATP” (Sodium Aluminum Titanium Phosphate)
Customized Cathode – Solid Electrolyte Compositions
NEI has developed processes to combine cathode particles and solid electrolyte materials. For example, in a composite morphology, the cathode and solid electrolyte particles are in intimate contact with each other and evenly distributed throughout the material. Customers can specify the cathode and solid electrolyte compositions of interest, and NEI can custom produce powders with the composite morphology.
Similarly, the solid electrolyte material can be deposited as a conformal film on cathode particles. Ionic conductivity measurements indicate that the ionic conductivity of the pristine solid electrolyte is largely preserved when it is combined with the cathode materials (the ionic conductivity of pristine solid electrolyte is 8 x 10-4 S/cm, whereas the ionic conductivity of solid electrolyte combined with a cathode is 5 x 10-4 S/cm). Finally, the composite material can be mixed with an ionically conducting binder and cast as a dense film. By making solid state electrolyte materials available in a more useable form, it is our intent to make it easy for Li-ion battery researchers to develop the next generation all-solid-state Li-ion batteries.
