The energy density of supercapacitors – battery-like devices that can charge in seconds or a few minutes – can be improved by increasing the ‘messiness’ of

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

The reason batteries come in so many types has as much to do with history as innovation.

New charts and data show how corporate demand could boost clean energy investment in regions where renewable energy potential is strong but wind and solar power have lagged.

It’s common to see solar panels on rooftops and fields, but they aren’t widespread on cars − yet.

The new rule isn’t a mandate for electric vehicles, but it will sharply increase their market share over the coming decade.

Electric vehicles are catching on across the US, but they’re also catching on fire in colder regions like the Northeast and Midwest.

Lithium-ion battery fires are becoming increasingly common as electric vehicles spread, and are hard to extinguish. A new approach uses an electrolyte based on a commercial fire extinguisher.

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

MIT chemists developed a battery cathode based on organic materials, which could reduce the EV industry’s reliance on scarce metals.
