Patent

CA 2679526

This invention relates to overcharge protection and molecular redox shuttles in rechargeable lithium-ion cells. For this, specific nitroxyls or oxoammonium salts are used in the electrolyte. This invention also relates to a method of producing such lithium-ion cells and to a method of recharging such lithium-ion cells. This invention also pertains to some nitroxyls compounds and oxoammonium salts.

Cette invention porte sur une protection contre les surcharges et sur des navettes redox moléculaires dans des piles lithium-ion rechargeables. Par conséquent, des nitroxyles spécifiques ou des sels d'oxoammonium sont utilisés dans l'électrolyte. Cette invention porte également sur un procédé de fabrication de telles piles lithium-ion et sur un procédé de recharge de celles-ci. Cette invention porte également sur certains composés nitroxyles et des sels d'oxoammonium.
