Batterie aqueuse pouvant être rechargée dans 30 secondes

Des chercheurs sud-coréens ont mis au point un dispositif de stockage d'énergie hybride aqueux qui peut être chargé en 20 à 30 secondes via un câble USB ou un panneau solaire.

Le dispositif affichait une densité de puissance 100 fois supérieure à celle des batteries aqueuses conventionnelles tout en conservant une capacité de 100% à un courant de charge / décharge élevé. L'anode a été fabriquée à partir d'un polymère à base de graphène et d'une cathode à partir d'un oxyde métallique.
