Bidirectional charging is the next big stage for electric vehicles. But storing power in your car and sending it back to your house involves more than flipping a switch.

Lithium is essential for batteries that power electric vehicles and store energy from solar and wind farms. A new U.S. source could provide 10 times more lithium than the country uses today.

Electric vehicle batteries, wind turbine generators and hydrogen fuel cells are among technologies likely to be affected by the conflict.

A newly-established Cambridge research centre will work to develop next-generation batteries and battery materials, one of the major technological hurdles in

A team of researchers found 35,000 pairs of existing reservoirs, lakes and old mines in the US that could be turned into long-term energy storage – and they don’t need dams on rivers.

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

Renewable energy is expanding at a record pace, but still not fast enough. Here are the key areas to watch for progress in bringing more wind and solar into the power grid in 2022.

The rechargeable battery can be woven and washed, and could provide power for fiber-based electronic devices and sensors.

A new way of processing rare-earth and other key metals to separate them from other materials could reduce environmental impact and cost.

Researchers make the case for a semisolid electrochemical compound as a cost-efficient, grid-scale battery backup for wind and solar power.
