The physics of better batteries

Harvard University researchers are using physics to solve one of the biggest challenges in designing light-weight, long-lasting batteries: how to squeeze more energy into less space.

Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and the Department of Physics have developed a tunable, electrochemical system that can store large amounts of energy in the space between atomically thin sheets of layered two-dimensional materials, like graphene.

The research is published in Nature.
