Study Sheds New Light on Why Batteries Go Bad

A comprehensive look at how tiny particles in a lithium ion battery electrode behave shows that rapid-charging the battery and using it to do high-power, rapidly draining work may not be as damaging as researchers had thought – and that the benefits of slow draining and charging may have been overestimated.

A Look Inside SLAC’s Battery Lab

Tucked in a small laboratory at the Department of Energy's SLAC National Accelerator Laboratory, a team of scientists from the Stanford Institute for Materials and Energy Sciences (SIMES) is making and testing new types of lithium-ion batteries. Their goal: create a battery five times better than the ones we use today.

'Smart Window' Material May Make Better Batteries

Windows that darken to filter out sunlight in response to electric current, function much like batteries. Now, X-ray studies at SLAC provide a crystal-clear view into how this color-changing material behaves in a working battery – information that could benefit next-generation rechargeable batteries.
