The U.S. Army’s premier research laboratory received a patent Tuesday on new battery technology with military and civilian applications.

The new invention is titled High Voltage Lithium Ion Positive Electrode Material and is now protected by U.S. Patent 10,147,946, according to documents from the U.S. Patent and Trademark Office.

The patent, issued on December 4, lists inventors Jan Allen, Joshua Allen, Samuel Delp, III, Jeffrey Wolfenstine, and T. Richard Jow, from the Army Research Laboratory in Adelphi, Maryland.

The Army Research Laboratory is developing new, lighter batteries that last longer. This particular electrode has a strong abuse tolerance, improved discharge, and low capacity fade, giving the battery a longer useful life.

TechLink, the Department of Defense’s national partnership intermediary for technology transfer, is seeking businesses interested in developing the battery technology into new products and services.

Through technology transfer, DoD inventions are made available to businesses and entrepreneurs for use in new products and services. The Army Research Laboratory has over 800 technologies in its patent portfolio.

A patent license confers to a business the right to practice the invention for commercial purposes and often includes related data and technical knowledge. License fees paid to the laboratory are typically negotiable.

To receive more information on this technology, interested parties can contact Brian Metzger, senior technology manager at TechLink, at or 406-994-7782.
