Researchers investigate batteries without critical raw materials

The market for rechargeable batteries is growing rapidly, but the necessary raw materials are limited. Sodium-ion batteries, for example, could offer an alternative. A joint research group from HZB and Humboldt-Universität ...

Generating power where seawater and river water meet

Scientists have known since the 1950s that it is theoretically possible to generate electricity through the movement of water in locations where seawater and river water meet. This type of technology is called osmotic power ...
