Title
(EN) NOVEL REDOX SHUTTLES FOR OVERCHARGE PROTECTION OF LITHIUM BATTERIES
(FR) NOUVELLES NAVETTES REDOX DE PROTECTION CONTRE LES SURCHAGES DE BATTERIES AU LITHIUM
Abstract
(EN)
The present invention is generally related to electrolytes containing novel redox shuttles for overcharge protection of lithium-ion batteries. The redox shuttles are capable of thousands hours of overcharge tolerance and have a redox potential at about 3-5.5 V vs. Li and particularly about 4;4-4.8 V vs. Li. Accordingly, in one aspect the invention provides electrolytes comprising an alkali metal salt; a polar aprotic solvent; and a redox shuttle additive that is an aromatic compound having at least one aromatic ring with four or more electronegative substituents, two or more oxygen atoms bonded to the aromatic ring, and no hydrogen atoms bonded to the aromatic ring; and wherein the electrolyte solution is substantially non-aqueous. Further there are provided electrochemical devices employing the electrolyte and methods of making the electrolyte.

La présente invention concerne habituellement les électrolytes contenant de nouvelles navettes rédox de protection des batteries au lithium. Les navettes rédox peuvent tolérer des milliers d'heures de surcharge et disposent d'un potentiel de rédox d'environ 3-5,5 V vs Li et particulièrement d'environ 4;4-4,8 V vs Li. En conséquence, un aspect de l'invention fournit des électrolytes comprenant un sel de métal alcalin, un solvant aprotique polaire, un additif de navette rédox qui est un composant aromatique possédant au moins un noyau aromatique avec au moins 4 substituants électronégatifs, au moins 2 atomes d'oxygène liés au noyau aromatique, et aucun atome d'hydrogène lié au noyau aromatique; et dans laquelle la solution électrolyte est essentiellement non aqueuse. De plus, l'invention comprend des dispositifs électromécaniques utilisant l'électrolyte et les procédés de fabrication de l'électrolyte.
