Title:
ELECTRODE FOR LITHIUM-ION BATTERY, AND LITHIUM-ION BATTERY
Document Type and Number:
WIPO Patent Application WO/2023/191032
Kind Code:
A1
Abstract:
Provided is an electrode for a lithium-ion battery that achieves both high capacity and charge/discharge performance and has improved handling properties in the manufacturing process. The electrode for a lithium-ion battery comprises: a current collector; and an electrode active material layer in contact with one surface of the current collector. The current collector contains a resin and at least one type of conductive filler, and has an average thickness of 30 to 100 μm. The electrode active material layer includes coated electrode active material particles in which at least a portion of the surface of an electrode active material particle is coated with a coating layer containing a polymer compound and a conductive filler. The average thickness of the electrode active material layer is 160 to 1100 μm, and is 5 to 22 times the average thickness of the current collector.
