NEI Announces Ready-to-Cast Solid Electrolyte Slurry for Lithium Ion Batteries


January 21, 2015

Somerset, New Jersey (USA) – NEI Corporation, a leading developer and manufacturer of specialty cathode, anode, and electrolyte materials for Lithium-ion batteries, announced today that they are expanding their offering of patent-pending, 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). SSE-10, which has now been used by a multitude of scientists and engineers for developing and prototyping “all solid” Lithium batteries, is now being made available in the form of a slurry or dispersion that can be cast into flexible tapes. NANOMYTE® SSE-10D is composed of surface-modified LSPS particles dispersed in organic solvent, which can be removed after the tape or film is formed.

Lithium Tin Phosphorous Sulfide (LSPS) belongs to a family of “superionic” solids, which have demonstrated high conductivity for lithium ions at room temperature. 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. Sulfur-based superionic solids with high Li-ion conductivity (10-3 S/cm) at room temperature (and more than an order of magnitude higher at 60 oC) were not commercially available until more than a year ago, when NEI first introduced LSPS in powder form. Since then, SSE-10 powder has been tested by industrial corporations (automotive, electronics, oil & gas) as well as academic and research institutes. By offering the material in slurry form, SSE-10D is readily castable into films & tapes and provides more options for cell designers to combine with suitable cathode and anode active materials. Additionally, SSE-10D allows limited atmospheric stability to the solid electrolyte particles, which otherwise need to be handled in a controlled environment.

NANOMYTE® SSE-10D is available in small as well as bulk quantities, and it can be supplied in customized formulations, with the addition of an active material (such as LCO, LFP, NCA, LMNO, graphite, and LTO).

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 NANOMYTE® SSE-10 last year, and now SSE-10D, 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.
