Detroit, Michigan – A new, patented material that can make advanced lithium-ion batteries last longer between charges has been licensed to General Motors by the U.S. Department of Energy’s Argonne National Laboratory, which developed the material.
The composite cathode material can also allow the batteries to be charged at higher voltages and will improve the inherent safety of lithium-ion cells.
“The creation of this battery technology represents an important return on the American investment in innovative vehicle and battery research,” said Energy Secretary Steven Chu. “This agreement gives General Motors the ability to use cutting-edge battery technology throughout its supply chain. The licensing of this technology will also spur the renewal of the American battery industry, creating hundreds of new jobs where they are needed most.”
The cathode material licensed to the automaker is part of a large and diverse suite of lithium-ion battery inventions and patents developed at Argonne with government funding.
Argonne has also licensed the cathode technology to LG Chem for use in battery cells used in the Chevrolet Volt.
