Title (EN) NONAQUEOUS ELECTROLYTE, NONAQUEOUS ELECTROLYTE ENERGY STORAGE DEVICE, AND METHOD FOR PRODUCING NONAQUEOUS ELECTROLYTE ENERGY STORAGE DEVICE
(FR) ÉLECTROLYTE NON AQUEUX, DISPOSITIF DE STOCKAGE D'ÉNERGIE À ÉLECTROLYTE NON AQUEUX, ET PROCÉDÉ DE PRODUCTION D'UN DISPOSITIF DE STOCKAGE D'ÉNERGIE À ÉLECTROLYTE NON AQUEUX
Abstract:
(EN) Provided is a nonaqueous electrolyte capable of enhancing coulombic efficiency after charge-discharge cycles at a high voltage of a nonaqueous electrolyte energy storage device, a nonaqueous electrolyte energy storage device having high coulombic efficiency after charge- discharge cycles at a high voltage, and a method for producing such a nonaqueous electrolyte energy storage device. One embodiment of the present invention is a nonaqueous electrolyte for an energy storage device containing an aromatic compound having a silyl group or an amino group, and an acetylenediyl group. Another embodiment of the present invention is a nonaqueous electrolyte energy storage device including the nonaqueous electrolyte.
(FR) L'invention concerne un électrolyte non aqueux susceptible d'améliorer l'efficacité coulombienne après des cycles de charge-décharge à une tension élevée d'un dispositif de stockage d'énergie à électrolyte non aqueux, un dispositif de stockage d'énergie à électrolyte non aqueux ayant une efficacité coulombienne élevée après des cycles de charge-décharge à une tension élevée, et un procédé de production d'un tel dispositif de stockage d'énergie à électrolyte non aqueux. Un mode de réalisation de la présente invention est un électrolyte non aqueux pour un dispositif de stockage d'énergie contenant un composé aromatique ayant un groupe silyle ou un groupe amine, et un groupe acétylènediyle. Un autre mode de réalisation de la présente invention est un dispositif de stockage d'énergie à électrolyte non aqueux comprenant l'électrolyte non aqueux.
