Abstract
A negative electrode for a secondary battery, including a negative electrode protective layer which can be formed by a simplified method and can effectively suppress the growth of acicular dendrites generated in the negative electrode of a lithium metal secondary battery. The negative electrode for the secondary battery includes a negative electrode current collector; a lithium metal film on the negative electrode current collector; and a negative electrode protective layer including a diazonium ion bonded to the lithium metal film.
