Perfect Lithium files key lithium-ion battery material patents

April 3, 2013

Patent pending technology describes industrially scalable methods to cut
costs and to boost performance of nano-scale ceramic powders including
lithium-ion battery materials for mobile devices, electric vehicles and
grid storage.

VANCOUVER, April 3, 2013 /PRNewswire/ – Vancouver-based Perfect Lithium Corp.
(“Perfect Lithium or the “Company”) has filed patents for its
innovative materials processing technology. These novel methods have
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

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.
