摘要

An electrode for a lithium-ion battery comprising a binder formed from a blend of two polymers, a first polymer which is one of a first polyacrylate or a derivative thereof, a second polyacrylate or a second polymer which is one of carboxymethylcellulose or derivatives thereof, An ink for producing such an electrode. An electrode for a lithium accumulator or lithium battery comprising: - a silicon-based active electrode material, - Conductors, A binder comprising a blend of two polymers: a first polymer having a first molecular weight, wherein the first polymer is one of a first polyacrylate or a derivative thereof, a second polymer having a second molecular weight, the second polymer being one of a second polyacrylate or carboxymethylcellulose, or a derivative thereof. The first molecular weight is 400,000 g / mol or less and 150,000 g / mol or more. The second molecular weight is not less than 650,000 g / mol but not more than 4,000,000 g / mol.
