ELECTRODE FOR LITHIUM SECONDARY BATTERY HAVING SPECIFIC COMPOSITION CONDITIONS AND LITHIUM SECONDARY BATTERY COMPRISING SAME

Document Type and Number:

WIPO Patent Application WO/2020/263023

Kind Code:

A1

Abstract:

The present invention relates to an electrode for a lithium secondary battery and a lithium secondary battery comprising same, the electrode having: a current collector; and an electrode material layer comprising an active material and a binder on at least one surface of the current collector. When the electrode material layer is divided into halves with respect to thickness and the upper layer further away from the current collector and corresponding to a 1/2 thickness is referred to as A electrode material layer and the lower layer closer to the current collector and corresponding to a 1/2 thickness is referred to as B electrode material layer, the A electrode material layer and B electrode material layer respectively comprise one or more active material layers and satisfy all of specific conditions (1) to (3) stated in the claims.
