Aqua Metals is building a more sustainable battery recycling ecosystem

Charged EVs

Several companies are developing chemical processes, but these are still at pilot scale, and Aqua’s execs see serious challenges in delivering the required product purity and dealing with waste streams. There are real challenges with waste streams—they yield a lot of sulfuric acid and sodium sulfate, which will need to get landfilled.

Energy Harvesting for Wearable Technology Steps Up

Cars That Think

The team was inspired by self-winding watches , which have existed since the late 18th century and transform wrist movement into energy. The team is in talks with the Tilburg, Netherlands–based company Kinetron to make a microgenerator designed specifically for animals, rather than self-winding wristwatches, Gregersen says.

Molten-Salt Battery Freezes Energy Over a Whole Season

Cars That Think

Especially for sources like wind and solar, which have discontinuous availability. They used nickel and aluminium as materials for the cathode and anode respectively, with sodium aluminium tetrachloride (NaAlCl 4 ) as the molten-salt electrolyte—all relatively cheap, earth-abundant materials.
