Summary: | The energy storage device, such as a lead-acid battery, includes an electrode comprising lead, an electrode comprising lead dioxide, a separator between the electrode comprising lead and the electrode comprising lead dioxide, and an aqueous electrolyte solution containing sulfuric acid. Also included are a first carbon-based additive having a surface area from 100 m2/g to 2000 m2/g, wherein the first carbon-based additive is functionalized with ¨S03 or ¨COOH, and a second carbon-based additive having a surface area from 3 m2/g to 50 m2/g.
Le dispositif de stockage dénergie, comme une batterie daccumulateurs au plomb, comprend une électrode comprenant du plomb, une électrode comprenant du dioxyde de plomb, un séparateur entre lélectrode comprenant du plomb et celui comprenant du dioxyde de plomb, et un électrolyte en solution aqueuse contenant de lacide sulfurique. Un premier additif à base de carbone ayant une surface de 100 à 2 000 m2/g dans laquelle le premier additif à base de carbone est fonctionnalisé avec ~S03 ou ~COOH, et un deuxième additif à base de carbone ayant une surface de 3 à 50 m2/g. |
