Beschreibung
Zusammenfassung:	Provided is a slurry composition that can be used in manufacturing an electrode of a lithium-ion battery. The slurry composition comprises a binder, a solvent, an electrode active material, and an additive. The additive can be a compound described by the general formula (1). The binder is a copolymer comprising of one or more hydrophilic structural units and one or more hydrophobic structural units. The addition of the additive improves electrode flexibility significantly. A method to produce electrodes using this slurry is also disclosed. In addition, battery cells containing the electrode prepared using the slurry composition disclosed herein exhibit exceptional electrochemical performance.
