A new coating could finally make lithium metal batteries safe and long-lasting, which may help usher in the next generation of electric vehicles.

Hydrogen seems to be the culprit behind the short lifespans of sodium-ion batteries, a potential replacement for costly lithium-ion batteries.

With more investment, better energy storage for wind and solar power could prevent extra energy from being wasted and cut greenhouse gas emissions.

A new battery technology can capture "blue energy" from places where saltwater and freshwater mix and constantly keep itself charged.

Wireless charging may be handy, but new research shows it can mess with your phone's battery and even shorten how long your device will last.

Cracks can be a big problem for solid-state batteries, so researchers are looking deeper to figure out the issue.

A new imaging technique for lithium-ion battery electrodes could lead to more reliable batteries with higher charging capacity.

A new supercapacitor shows solid performance and stability—even when researchers stretch it to 800 percent of its original size.

A set of devices that act as artificial synapses, mimicking the way neurons communicate in the brain, performs even better than researchers hoped.

Dropping electronics can seriously damage their batteries. A device that can stand up to a car crash could change that.
