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."

A new 1,000 cycle lithium-sulfur battery made with nanofibers recycled from Kevlar has the potential to quintuple the range of electric cars.

Does using your phone's dark mode feature actually help your battery last longer? Researchers digging into the question say, "probably not."

When, where, and how electric delivery fleet vehicles are charged can greatly affect their potential to reduce greenhouse gas emissions, researchers report.

A new type of metal-free battery non-toxic and safer across the board. It can also degrade on demand, paving the way for better recycling.
