Abstract[English]
The present inventions relate to methods, systems, apparatuses, controllers, software, and composition of matter associated with electrochemical energy storage devices. The present inventions relate to one or more additives for batteries, e.g., silicon-based batteries. The additives are integrated in the electrode counter-electrode, and/or electrolyte. The additives are configured to enhance electrochemical kinetics, reduce overpotential, suppress parasitic reactions, stabilize passivation layers, suppress dendrite formation, improve capacity retention, enable fast charging, increase coulombic efficiency, enhance reversibility over extended cycling, or any combination thereof.[French]
La présente invention concerne des procédés, des systèmes, des appareils, des dispositifs de commande, un logiciel et une composition de matière associés à des dispositifs de stockage d'énergie électrochimique. La présente invention concerne un ou plusieurs additifs pour batteries, par exemple pour des batteries à base de silicium. Les additifs sont intégrés dans la contre-électrode d'électrode et/ou dans l'électrolyte. Les additifs sont conçus pour améliorer la cinétique électrochimique, réduire le surpotentiel, supprimer les réactions parasites, stabiliser les couches de passivation, supprimer la formation de dendrites, améliorer la rétention de capacité, permettre une charge rapide, augmenter l'efficacité coulombique, améliorer la réversibilité sur un cyclage prolongé, ou pour offrir toute combinaison de ces effets.
