POLYMER COMPOSITION AS A BINDER SYSTEM FOR LITHIUM-ION BATTERIES

摘要

The invention relates to an electrode coating for a lithium-ion battery, containing copolymer C or the salt thereof, copolymer C being synthesized by polymerizing a combined total of more than 70 wt% of vinyl-functional cyclic carbonate and one or more monomers from the group comprising acrylic acid and the derivatives thereof, the percentage by weight of vinyl-functional cyclic carbonate in relation to the weight of all monomers used being 5-90%.
