Practical Graphene Technologies for Electrochemical Energy Storage

Killer applications of graphenes are always being pursued and critical for realizing industrialization. Since the first attempt for using graphene in lithium-ion batteries, graphene has been demonstrated as a key component in electrochemical energy storage technologies. However, the unique roles of graphene beyond traditional carbon in energy storage are still unclear and need to be clarified. Here, this review starts with a glance over the history of graphene in electrochemical energy storage applications, and then briefly discusses the different dimensional graphenes and representative synthesis methods that are believed to be essential for energy-related applications. Importantly, three typical graphene technologies showing their practical potentials in electrochemical energy storage are illustrated in details, including the uses as conductive additives, in heat dissipation, and compact energy storage. The methodologies of science and technology for the above applications are systematically elaborated. This review also gives perspectives on the opportunities and challenges of practical graphene technologies in electrochemical energy storage. The authors expect this review to provide a comprehensive view of how graphene can be uniquely and practically used for electrochemical energy storage, paving the way for promoting the development of the graphene industry.
