Title
(EN) LITHIUM-ION BATTERY
(FR) BATTERIE À IONS LITHIUM
Abstract
(EN) A lithium-ion battery includes a positive electrode that includes a positive current collector, a first active material, and a second active material. The lithium-ion battery also includes a negative electrode comprising a negative current collector, a third active material, and a quantity of lithium in electrical contact with the negative current collector. The first active material, second active material, and third active materials are configured to allow doping and undoping of lithium ions, and the second active material exhibits charging and discharging capacity below a corrosion potential of the negative current collector and above a decomposition potential of the first active material.
(FR) Batterie à ions lithium comprenant une électrode positive avec collecteur de courant positif, premier matériau actif et second matériau actif. La batterie à ions lithium comprend également une électrode négative avec collecteur de courant négatif, troisième matériau actif et une quantité de lithium en contact électrique avec le collecteur de courant négatif. Le premier, le deuxième et le troisième matériaux actifs sont conçus pour permettre le dopage et le non dopage des ions lithium. Le second matériau actif possède une capacité de charge et de décharge au-dessous du potentiel de corrosion du collecteur de courant négatif et au-dessus d'un potentiel de décomposition du premier matériau actif.
