Abstract:
A negative electrode includes an active material. The active material includes a silicon-based core and a two-dimensional, layered mesoporous carbon coating in continuous contact with the silicon-based core. The two-dimensional, layered mesoporous carbon coating is capable of expanding and contracting with the silicon-based core. The negative electrode also includes a binder.
