Pacific Northwest National Laboratory developing higher-quality batteries

July 18, 2010View for printing

A cell phone battery could fully charge in 10 minutes rather than two to five hours using technology developed by Pacific Northwest National Laboratory , Princeton University and a Maryland company.

Researchers at the Department of Energy’s Richland laboratory, working with Vorbeck Materials Corp. and Princeton University scientists, have demonstrated that adding small quantities of high-quality graphene to battery materials can dramatically improve their performance.

The addition of graphene improves a lithium-ion battery’s ability to recharge repeatedly after it has been fully drained and makes charging much faster, said Jun Liu, a PNNL laboratory fellow for material sciences.

The technology also could allow batteries to store larger amounts of energy.
