Incorporating graphene, a team of scientists at Pacific Northwest National Laboratory, Vorbeck Materials Corp., and Princeton University have developed a nanocomposite material that can greatly improve the performance of lithium-ion batteries. Small quantities of graphene can deliver increased battery capacity, longer cycle life, and increased specific power at a high charge-discharge rate. These batteries could drastically reduce the time it takes to charge a smartphone to as little as 10 minutes and an electric vehicle to just a few hours. Improving charge time and these other battery characteristics could significantly expand the adoption and use of electric vehicles. EERE provided support for the project that led to this discovery.

In 2012, R&D Magazine recognized this accomplishment as part of its R&D 100 awards. This award recognizes the year's 100 most significant scientific and technological products or advances.
