Perfect Lithium files key lithium-ion battery material patents



Vancouver-based Perfect Lithium has filed patents for its innovative materials processing technology, with the potential to reduce energy storage costs ($/kWh) of lithium-ion battery materials by as much as 50%. The patent-pending technology is an innovative application of industrially scalable methods to form fine, ultra-fine, nano-scale and uniform ceramic powders. It has wide applicability in dental, bio-medical, pharmaceutical, aerospace, communication, optical, chemical, semi-conductor and energy storage sectors. Perfect Lithium's immediate focus is on optimizing the process for lithium-ion battery materials. The efficiency gains are achieved by reducing raw material input requirements, by simplifying the methods of processing these raw materials, and by providing unique nanostructures that enhance performance characteristics such as energy storage, power and cycling. Today's battery materials are prepared using a variety of different methods, requiring time consuming, labour intensive and high-energy procedures, often with expensive solvents and reactants. Up-and-coming battery materials are often encumbered by economically impractical procedures that impede ease of scale-up for commercialization. Perfect Lithium's methods do not require rigorous and intensive steps such as the repetitive grinding, milling and blending currently in common use. The process takes place at ambient or mild temperatures and standard pressures, eliminating needs for super or subcritical conditions. There are no expensive chemicals nor reactants and normal procedures such as filtering and washing are not required. In some cases, up to 75% of the steps have been eliminated. The patent pending methodology will bring much needed efficiency gains to the preparation of today's lithium-ion cathode materials and it will also provide a scalable and economically viable production route for next generation battery materials in electronics, transportation and grid storage applications. Perfect Lithium is executing its plans, on schedule and on budget. A robust portfolio of intellectual property has already begun, there is ongoing optimization for a variety of materials and there are plans for a piloting phase in 2014. With key patents now filed, the Company is in a position to further negotiations with a number of interested companies. It is Perfect Lithium's intention to leverage the value of its unique technologies and seek strategic partnerships and financiers to assist with the piloting, licensing and deployment of the technology into the multifaceted battery space.
