Abstract
The present disclosure relates to a negative electrode for a lithium secondary battery, a method for manufacturing the negative electrode, and the lithium secondary battery including the negative electrode. The negative electrode can include a negative electrode current collector layer, a silicon-based negative electrode active material layer provided on at least one surface of the negative electrode current collector layer, and a ceramic layer provided on a surface of the silicon-based negative electrode active material layer opposite to a surface of the negative electrode active material layer facing the negative electrode current collector layer. The ceramic layer can include a ceramic layer composition or a dried product thereof, and the ceramic layer composition can include ceramic and a binder. BaTiO3 can be included in an amount of 10 parts by weight or more and 50 parts by weight or less based on 100 parts by weight of the ceramic.
