Des batteries solides

David Silverberg, BBC :

Batteries need to make progress, admits Prof Yoshino, but thankfully, “there’s a lot of interesting approaches”. And “the solid state battery, I think, is a promising one,” he says. […] But despite those worries, solid state batteries have “had the breakthrough in basic research, and research and development for mass production techniques is progressing,” says Prof Yoshino. He thinks it could take another 10 years for solid state batteries to compete with lithium-ion in terms of price.

Akira Yoshino est un des colauréats du prix Nobel 2019 de chimie. La recherche sur les « batteries solides » progresse doucement, mais surement. Loz Blain, New Atlas :

Researchers at Australia’s Deakin University say they’ve managed to use common industrial polymers to create solid electrolytes, opening the door to double-density solid state lithium batteries that won’t explode or catch fire if they overheat. Dr. Fangfang Chen and Dr. Xiaoen Wang from Deakin’s Institute for Frontier Materials claim to have made a breakthrough with “the first clear and useful example of liquid-free and efficient transportation of lithium-ion in the scientific community.”

Les chercheurs travaillent sur des cellules en forme de bouton. L’enjeu consiste à passer aux cellules en forme de baton ou de sachet, et donc de concevoir les processus industriels permettant de produire ces nouvelles batteries à l’échelle nécessaire aux industries technologique et automobile.
