Negative electrode for rapidly rechargeable lithium secondary battery and manufacturing method thereof
Abstract:
Disclosed is a rapidly rechargeable lithium secondary battery. The present invention provides a negative electrode for a lithium secondary battery, the negative electrode being characterized by including: a current collector; a negative electrode material layer which is formed on the current collector and includes negative electrode active material particles, conductive material particles, and a binder; and a surface layer which is formed on the surface of the negative electrode material layer, is formed of insulating particles that are inert with respect to lithium, and partially shields the negative electrode material layer. According to the present invention, a negative electrode for a lithium secondary battery having a high charging speed without lifetime degradation can be provided.
