Abstract

The present invention relates to an electrode composition for a cathode of a cell of a lithium-ion battery comprising an epoxy group-containing fluorine-free copolymer, a cathode slurry composition comprising the electrode composition, a cathode, a process for manufacturing this cathode, and a lithium-ion battery having one or more cells incorporating this cathode.

Description

technical field [0001] The present invention relates to an electrode composition used for the cathode of a battery cell of a lithium ion battery, the electrode composition comprising a fluorine-free copolymer containing an epoxy group; a cathode slurry composition comprising the electrode composition; a A cathode; a method for making the cathode; and a lithium ion battery having one or more battery cells incorporating the cathode. Background technique [0002] A Li-ion battery consists of at least two conductive Coulomb electrodes of different polarity: a negative electrode or anode (usually made of graphite) and a positive electrode or cathode, with a separator between the two electrodes made of Li-based + The electrical insulator consists of an aprotic electrolyte impregnated with ionic cations, thus ensuring ionic conductivity. The electrolytes used in these lithium-ion batteries are typically composed of lithium salts such as LiPF 6 , LiAsF 6 、LiCF 3 SO 3 or LiCO 4...
