Valence Receives Patent for Phosphate Technology

Valence Technology, Inc. of Austin, Texas, has been granted U.S. patent 7,001,690 entitled “Lithium-based Active Materials and Preparation Thereof” which relates to the company’s Saphion I technology, the key component of its rechargeable lithium-ion battery systems.

A key benefit of Saphion I technology is its inherent electrochemical stability, which enables the creation of large, high energy density lithium-ion batteries. It utilizes natural, phosphate-based cathode material in place of the less stable and more costly cobalt-oxide used in most of today’s Li-ion batteries. As a result, battery systems can be designed into a wide variety of products in markets not previously served by traditional Li-ion batteries.

“Our Saphion battery systems have been commercially available for more than three years and are steadily gaining traction in a number of markets, including motive, health care, education and defense,” says Dr. James Akridge, president and CEO of Valence Technology, Inc.
