(EN) ADDITIVE FOR NON-AQUEOUS ELECTROLYTE AND SECONDARY BATTERY USING THE SAME
(FR) ADDITIF POUR ÉLECTROLYTE NON AQUEUX ET BATTERIE SECONDAIRE L'UTILISANT
Abrégé
(EN)
Disclosed is an electrolyte comprising a compound having both a sulfonate group and a cyclic carbonate group. The electrolyte forms a more stable and dense SEI layer on the surface of an anode, and thus improves the capacity maintenance characteristics and lifespan characteristics of a battery. Also, disclosed is a novel compound, and a method for preparing the same by reacting 4-(hydroxyalkyl)-1,3-dioxolan-2-one with a sulfonyl halide compound:
(FR)
L'invention concerne un électrolyte comprenant un composé ayant un groupe sulfonate et un groupe carbonate cyclique. L'électrolyte forme une couche SEI plus stable et plus dense sur la surface d'une anode, ce qui améliore les caractéristiques de maintenance de capacité et de durée de vie d'une batterie. En outre, l'invention concerne un nouveau composé, ainsi qu'un procédé de préparation de ce composé au cours duquel 4-(hydroxyalkyl)-1,3-dioxolan-2-one réagit avec un composé halogénure de sulfonyle.
