Researchers used a robotic lab to mix unconventional ingredients in just the right order to make complex materials for batteries.

A sensor that uses energy from sound waves to control electronic devices could, one day, save millions of batteries.

Researchers say the key to making batteries last longer may come from a mundane source: the way soap works.

Cracks in lithium-ion batteries actually speed up electric vehicle charging. This runs counter to the view of many EV manufacturers.

Nickel could reduce or even eliminate the use of cobalt in lithium-ion batteries, which is often mined using child labor.

A new elastic material could be used to create flexible batteries for "soft" electronics. It's impervious to gases and liquids.

Adding more salt to a polymer-based electrolyte can keep batteries working without catching fire when heated to over 140 degrees F.

In this podcast episode, Shirley Meng details the crucial race to build a better battery—one that lasts longer and charges faster.

"The goal is to design a better battery and, traditionally, the industry has tried to do that using trial and error testing." New work may speed things up.

"This study really sheds light on how we can design and manufacture battery electrodes to obtain long cycle life for batteries."
