NEI Introduces Custom-Produced Solid Electrolyte Materials

June 17, 2015

Somerset, New Jersey (USA) – NEI Corporation, a leading developer and manufacturer of specialty cathode, anode, and electrolyte materials for Lithium-ion batteries, has announced an expansion of its services for producing Custom Solid Electrolyte Materials. Most commercial Lithium-ion batteries usually contain an electrolyte that is dissolved in flammable solvents. The use of a solid electrolyte eliminates the flammability issue associated with currently used liquid electrolytes. Customers can now purchase solid electrolyte materials with the composition of their choice. Whether it is an oxide material (e.g., LATP, LLTO, LNBO or any other mixed metal oxide) or a sulfide material (e.g., LPS, LSPS, or composites of sulfide containing compounds), NEI can produce powders anywhere in the range of small lot quantities to multiple kilograms. Additionally, the primary particle size can be reduced further into the ultrafine or nanoscale regime, if needed.

NEI has also 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.

NEI Custom Solid ElectrolytesNEI’s Custom Solid Electrolyte Materials services build upon NEI’s patent-pending, ready-to-cast, solid electrolyte materials. Over the past year, NEI has supplied multi-kilogram quantities of their newly developed solid electrolyte powder, NANOMYTE® SSE-10 (Li10SnP2S12 or LSPS). NANOMYTE® SSE-10, which has been used by a number of scientists and engineers for developing and prototyping “all solid” Lithium batteries, has also been made available in the form of a slurry (dispersion), NANOMYTE® SSE-10D, which can be cast into flexible tapes. SSE-10D is composed of surface-modified LSPS particles dispersed in organic solvent, which can be removed after the tape or film is formed.

NEI Corporation has been a long trusted source for customized cathode and anode materials used in lithium batteries. The company specializes in developing new compositions and particle morphologies, including nanoscale particle engineering. NEI also has an extensive battery research and characterization facility, which includes multi-channel cell testers. The introduction of NEI’s service for custom produced solid electrolytes will provide new capabilities to lithium battery developers and manufacturers to enable practical solid state batteries.

NEI Corporation and PneumatiCoat Technologies Sign Agreement to Jointly Develop and Market New Materials for Lithium-ion Batteries

September 9, 2014

Somerset, New Jersey (USA) – NEI Corporation (NEI) and PneumatiCoat Technologies (PCT) have initiated a collaboration to develop, produce, and market coated battery materials – cathodes, anodes, and solid electrolytes. The partnership will help serve the needs of customers interested in enhancing the performance of batteries through the use of Atomic Layer Deposition (ALD) coatings of active material particles. Key features of ALD-coated particles include improved cycle life, enhanced safety, and greater stability and abuse tolerance, particularly under higher temperature and voltage operation.

NEI Corporation has been a long trusted source for customized cathode and anode materials used in lithium batteries. The company specializes in developing new compositions and particle morphologies, including nanoscale particle engineering. NEI also has extensive battery research and characterization facility, which includes multi-channel cell testers. PneumatiCoat Technologies is a pioneer in autonomous coating systems that allow for high-rate manufacturing of ALD protected particles used in batteries and related energy storage devices. The ALD platform was originally developed in Europe, and PCT is now facilitating the transition of the ALD platform from slow and expensive to economical, robust and industrially-viable.

The NEI–PCT agreement allows customers access to ALD coatings on a variety of battery material compositions, including mixed metal oxides (Lithium Manganese Nickel Oxide – LMNO, NMC, LMO, NCA); phosphates, silicates, titanates, sulfides, graphite and silicon-based active materials. Customers have the flexibility to not only investigate new compositions and chemistries, but also consider the use of different ALD coatings, both passive and lithium-ion conducting. The NEI–PCT relationship provides customers with access to the technology cost-effectively.
