Three climate technologies breaking through in 2026

Happy New Year! I know it’s a bit late to say, but it never quite feels like the year has started until the new edition of our 10 Breakthrough Technologies list comes out.  For 25 years, MIT Technology Review has put together this package, which highlights the technologies that we think are...

Votre batterie de voiture électrique va durer bien plus longtemps que vous ne le pensez

Votre batterie de voiture électrique va durer bien plus longtemps que vous ne le pensez

C’était prévisible et j’ai envie de dire tant mieux ! Encore une saloperie en moins dans la liste des angoisses du technophile moderne qui hésite à passer à l'électrique par peur de voir sa batterie se transformer en brique de lithium inerte au bout de trois ans. Perso, je ne vois aucune raison de...

A sodium-ion battery works much like a lithium-ion one: It stores and releases energy by shuttling...

Listening to battery failure

Listening to battery failure

Lithium-ion batteries produce faint sounds as they charge, discharge, and degrade. But until now, nobody could interpret those sounds to detect when a battery might be about to lose power, fail, or burst into flames. Now, MIT engineers have found a way to do that, even with noisy data. The findings...
