The U.S. Department of Energy has awarded Southwest Research Institute (SwRI) $712,500 to investigate the behaviour of lithium-ion batteries during charge and discharge.
The contract is one of 19 projects being awarded funding by the DoE from the $43 million set aside for the Department’s Advanced Research Projects Agency-Energy (ARPA-E) to develop breakthrough energy storage technologies.
“This contract will give us the opportunity to analyze the capacity and health of lithium-ion batteries over time,” said Jeff Xu, a principal scientist in SwRI’s Engine, Emissions and Vehicle Research Division and a co-principal investigator of the project. “This early-stage development research is a new method for analyzing battery capacity and health that will help us improve lithium-ion battery life and recharge rates.”
“The research will utilize SwRI’s combined expertise in cell chemistry, cell testing and control system development to provide a positive contribution in the area of EV/HEV/PHEV safety,” added Joe Steiber, co-principal investigator and a principal engineer, also in the Engine, Emissions and Vehicle Research Division.
The SwRI project, entitled “Strain Estimation Technology for Lithium-Ion Batteries,” will take two years to complete and will explore the potential of tracking physical expansion and contraction of lithium-ion batteries during charge and discharge cycles.

I don't like paywalls. You don't like paywalls. Who likes paywalls? Here at CleanTechnica, we implemented a limited paywall for a while, but it always felt wrong — and it was always tough to decide what we should put behind there. In theory, your most exclusive and best content goes behind a paywall. But then fewer people read it! We just don't like paywalls, and so we've decided to ditch ours. Unfortunately, the media business is still a tough, cut-throat business with tiny margins. It's a never-ending Olympic challenge to stay above water or even perhaps — gasp — grow. So ...
