Scandium could boost sodium-ion batteries for longer life, study finds
As the world searches for alternatives to lithium-ion batteries, sodium-ion batteries are emerging as a promising solution.
Sodium is far more abundant in the Earth’s...
New sodium solid-state battery could rival lithium for electric vehicles
All-solid-state batteries are often called the future of energy storage.
They are safer and more powerful than today’s lithium-ion batteries, making them attractive for electric...
Batteries whisper before they fail — and scientists have learned to listen
Before a battery dies, loses power suddenly, or even catches fire, it doesn’t stay completely silent.
It makes tiny, faint sounds—like whispers—that reveal what’s happening...
Cornell’s new chip design slashes AI energy use by 20%
Artificial intelligence (AI) is getting stronger every year—but also more power-hungry.
Running large AI models takes a lot of electricity, raising concerns about the environmental...
How tiny defects threaten perovskite solar cells
Perovskite solar cells have been hailed as the next big thing in renewable energy.
