Pacific Northwest National Laboratory developing higher-quality batteries
A cell phone battery could fully charge in 10 minutes rather than two to five hours using technology developed by Pacific Northwest National Laboratory http://www.pnl.gov/ , 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.
