Grid-level storage of renewable energy using electrolytes from seawater is a platform technology with multiple byproducts and use-case scenarios. The core application is to provide load-leveling for intermittent sources such as wind and solar. Membranes [...]

Rechargeable Lithium-ion Batteries For Wireless Smart Designs

Mourzagh D., Rouault H., Jouanneau S., Daniel L., Chami M., Moreau G., Fusalba F., CEA-Grenoble, FR

Wireless communication is today considered as a disruptive technology. Indeed, even if wired systems can easily achieve 100% of reliability, it induces high amount of wiring, which has non negligible impact on the mass and [...]

Composite Li-Ion Anodes from Recycled Silicon

Xu W., Electrochemical Materials, US

Silicon byproducts from sources such as kerf are difficult to use directly as lithium-ion batteries since key parameters such as silicon particle size, surface oxides, and impurities, do not fulfill the requirements for silicon anode [...]
