Superlattice Power, Inc. (SLAT.OB), the North Carolina-based lithium battery developer, recently completed the filing of a patent for a proprietary chemical process used in industrial-scale production of new, high-purity nano cathode materials. The new materials are key to the development of the company’s advanced lithium ion polymer battery for use in high-range electric vehicles. The new battery increases electric vehicle range to approximately 200 miles, a major improvement over existing batteries, and promises to significantly enhance the marketability of electric cars. Industrial scale production of the material is essential, and has been aggressively pursued by Superlattice.
Superlattice has successfully produced some 200 kg of the new cathode material at its production facility in Mooresville, NC. The cobalt-free cathode material has a superlattice chemical structure. Superlattice structure is a hexagonal arrangement that can accommodate more lithium and therefore more energy. The elements and transition metals have been selected precisely to make superlattice cathode materials safe, environmentally friendly, and less expensive. The structure boosts battery energy density, range, charge rate, and durability, but requires unique chemical processes to produce in quantity.
Dr. Surajit Sengupta and Dr. Vishal Mahajan have take a leading role in performing associated research with a Fortune 500 electronics and telecommunication company to design prototype cells with high energy density. Hybrid Technologies, a Las Vegas-based developer and marketer of electric vehicles and conversions, has provided significant support in assisting Superlattice’s move from the laboratory to industrial-size production.
