The lithium-ion battery pack sitting under millions of electric vehicles on the road right now may be approaching a shelf ...

Electric vehicles have advanced rapidly over the past decade, but battery technology remains the ...

Some solid materials can cool down or heat up when pressure is applied or released. This behavior enables cooling and heating ...

A new AI-driven technique spots the telltale Raman signal of liquid-like ion motion—helping scientists rapidly identify ...

Solid-state batteries could be safer and more energy-dense than today’s lithium-ion technology, but finding materials that allow ions to move quickly through solid electrolytes has been difficult.

Researchers developed a stretchable polymer-based solid electrolyte that could enable safer, flexible solid-state batteries ...

We rely on batteries now more than ever, from our phones and laptops to electric vehicles. But the ones powering today's technologies aren't without their shortcomings. They can be expensive, ...

As useful as refrigerators and air conditioners are, the gases they use as refrigerants can leak into the atmosphere and become major contributors to climate change. Now engineers at Harvard have ...

Ultraviolet (UV) light has higher energy photons than visible light and, thus, has more applications. Researchers have now developed a brilliant innovation -- a solid-state material that can stably ...
