Graphene coating could help prevent lithium battery fires

Lithium batteries are what allow electric vehicles to travel several hundred miles on one charge. Their capacity for energy storage is well known, but so is their tendency to occasionally catch on fire—an occurrence known ...

Cause of cathode degradation identified for nickel-rich materials

A team of scientists including researchers at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory and SLAC National Accelerator Laboratory have identified the causes of degradation in a cathode material for ...

Making green cars greener with battery recycling

The widespread implementation of electric vehicles will go a long way toward eliminating the greenhouse gas emissions of the transportation sector. But these GHGs don't just come from the tailpipe. There's another major culprit ...

Lean electrolyte design is a game-changer for magnesium batteries

Researchers from the University of Houston and the Toyota Research Institute of America have discovered a promising new version of high-energy magnesium batteries, with potential applications ranging from electric vehicles ...

Stabilizing silver films for high-efficiency fuel cells

Solid oxide fuel cells (SOFCs) offer a stable and efficient way to generate clean electrochemical power, but are impractical for use in portable devices because of their high operating temperatures. A new design and production ...

A stabilizing influence enables lithium-sulfur battery evolution

In late July of 2008 a British solar plane set an unofficial flight-endurance record by remaining aloft for more than three days straight. Lithium-sulfur batteries emerged as one of the great technological advances that enabled ...
