摘要:
The negative electrode includes a current collector, a negative electrode active material layer arranged on a surface of the current collector, and a protective layer arranged on a surface of the negative electrode active material layer. The negative electrode active material layer includes a first negative electrode active material having an aspect ratio defined as “a”/“b” to fall in a range of from two or more to eight or less when a length of the major axis is defined “a” and a length of the minor axis is defined “b.” The protective layer includes a ceramic powder.
