Abstract
An electrode including a conductive metal support and a paste including an electrochemically-active material and a binder. The binder includes a compound of silane type, and a polymer having at least one acrylic monomer, and representing at least approximately 0.15% of the weight of said paste. The use of this binder improves the calendar or cycle life of the battery at a temperature greater than or equal to 25° C., preferably at a temperature greater than or equal to 40° C.
