METHOD OF PREPARING ELECTRODE FOR LITHIUM SECONDARY BATTERY AND ELECTRODE FOR LITHIUM SECONDARY BATTERY PREPARED THEREBY

Document Type and Number:

WIPO Patent Application WO/2018/016785

Kind Code:

A1

Abstract:

The present invention relates to a method of preparing an electrode for a lithium secondary battery and an electrode for a lithium secondary battery prepared thereby, wherein, since the method may suppress the migration of a binder and may uniformly control the distribution of the binder in the electrode by forming a plurality of negative electrode active material layers and allowing a drying condition of each of the negative electrode active material layers to be different, the method may improve life characteristics by improving adhesion between a negative electrode active material and a current collector and may improve charging characteristics by reducing interfacial resistance of the negative electrode.
