A new way to harvest power from 5G networks could make many of the batteries that power our devices a thing of the past, researchers say.

A new long-lasting, quick-charging electric car battery may offer a way to ease drivers' "range anxiety"—the fear of running out of power.

Fluorine, a relatively abundant and light element, may be a good substitute for lithium without changing how long batteries last much.

Batteries that can conform to the shape of a robot's body double as protection and far more efficient energy storage could pave the way for new bots.

A new method can convert 65-cent red bricks from Home Depot into a supercapacitor that can store electricity, researchers report.

Motors first designed for the International Space Station can help people using prosthetic legs to walk with a more natural gait, researchers say.

New technology can keep lithium batteries like those in our phones from heating up, failing, or exploding, researchers report.

A new technique that mirrors how scientists make graphene with lasers uses sticky tape to improve lithium metal batteries.

A new lithium-ion battery for electric cars offers both safety and high performance—and can last for 1 million miles.

Artificial intelligence has brought the dream of recharging electric vehicles in the time it takes to stop at a gas station closer to reality.
