Researchers develop alternative to lithium batteries

Lithium-ion batteries are currently the preferred technology to power electric vehicles, but they're too expensive for long-duration grid-scale energy storage systems, and lithium itself is becoming more challenging to access.

New scavenger technology allows robots to 'eat' metal for energy

When electronics need their own power sources, there are two basic options: batteries and harvesters. Batteries store energy internally, but are therefore heavy and have a limited supply. Harvesters, such as solar panels, ...

Investigating an innovative solution for thermal energy storage

Have you ever gotten relief from summertime heat by draping a wet towel over your head? If so, you've benefited from a phase-change material (PCM): a substance that releases or absorbs energy when it transitions between ...
