Islands of inactive lithium creep like worms to reconnect with their electrodes, restoring a battery’s capacity and lifespan.

Scientists who perform experiments at SLAC’s lightsources gathered online for research talks, workshops and discussions.

Storing the rechargeable batteries at sub-freezing temperatures can crack the battery cathode and separate it from other parts of the battery, a new study shows.

She toured the lab’s powerful X-ray laser, looked at the construction of the world’s largest digital camera, and discussed climate research, industries of the future, and diversity, equity and inclusion in the sciences.

Measuring the process in unprecedented detail gives them clues to how to minimize the problem and protect battery performance.

Scientists have documented a process that makes these next-gen batteries lose charge – and eventually some of their capacity for storing energy – even when a device is turned off.

The latest advance from a research collaboration with industry could dramatically accelerate the development of sturdier batteries for fast-charging electric vehicles. 

Presented by Yijin Liu. In batteries, energy is stored in tiny particles within the electrodes that individually breathe in and out and chemically evolve as the battery is charged and discharged.
