Abstract
The invention relates to a binder component for the cathode of a secondary lithium-ion cell, which consists of three components: PVDF of 69 to 94% by mass of the binder component, of which the PVDF has an average molecular weight of between 970,000 M and 1,100,000 M; PVDF-TFE of 3 to 30% by mass of the binder component, of which the PVDF-TFE has an average molecular weight of between 880,000 M and 920,000 M; and HNBR of 1 to 3% by mass of the binder component, of which the HNBR has an average molecular weight of between 280,000 M and 320,000 M.
