Batteries and electrochemical capacitors represent the most widely used types of electrochemical energy storage (EES) devices [1-3]. The future development of EES devices is strongly dependent on finding new materials that provide higher power, faster charging, and longer cycle life. Since the discovery of graphene, 2D layered materials have become of intense interest for both fundamental studies and energy applications. Recent results have shown that dimensionality is one of the critical parameters used to modulate physical and chemical properties of nanomaterials. For this reason, 2D nanosheets are quickly emerging as a promising direction for improving EES materials [4].
