Supertetrahedra Lego for future batteries

Wed, 05/23/2018 - 22:08
New sodium-based all-solid-state batteries could enable future energy storage devices using only the easy-to-access, cheap and earth abundant elements sodium, silicon and phosphorous (Na, Si and P). By shaping them into sodium phosphidosilicates containing large supertetrahedral entities, scientists generated solid electrolytes with very high ionic conductivity.

Moisture-powered electronics

Wed, 05/23/2018 - 12:31
Very different from piezoelectric and other energy harvesting technologies, new research shows that water vapor or moisture expand the range of natural phenomena that can be used to generate electric power. Researchers demonstrate that moisture, a vast kind of resource existing ubiquitously on earth and in biological organisms, can be exploited as a novel harvestable energy to generate electricity. Although some device configurations previously have been demonstrated to directly generate electricity from moisture, these generators have not been shown yet to be flexible and to be used as self-powered wearable devices.
