Practical Graphene Technologies for Electrochemical Energy Storage

Abstract

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.

“…It possesses many excellent physical and chemical properties, such as large specic surface area (2600 m 2 g −1 ), excellent electrical conductivity (106 S cm −1 ) and good mechanical strength. [182][183][184][185] Electrolyte ions can rapidly and repeatedly migrate between the graphene surface and electrolyte, which is the chief reason to provide great cycling stability and high specic capacity. 186 Doped graphene shows rich chemical functionalities by tunable chemical/hydrogen bonds, van der Waals interaction and ample defects.…”

Advanced Phase Change Materials from Natural Perspectives: Structural Design and Functional Applications

“…Thermal energy utilization has always been an important topic in human society, as it relates to almost all aspects of people's daily lives. [ 16 ] However, the management of thermal energy is challenging owing to its intermittency and discontinuity, resulting in low utilization efficiency. [ 17 ] PCMs are promising candidates for thermal management, which realize heat energy absorption and release during an isothermal phase transition process.…”

Siloxane‐Based Organosilicon Materials in Electrochemical Energy Storage Devices

“…[40] Specifically speaking, R/Si > 2 corresponds to low-molar-mass linear polysiloxane (1) or branched polysiloxanes (2) and (3). R/Si = 2 corresponds to a singlering polysiloxane structure with a low polymerization degree (4) and high-molar-mass linear polysiloxane (5). R/Si < 2 refers to network polymer (6), condensed ring (7), spiro (8), spherical ring (9) polysiloxanes with different crosslinking degrees and also T-shaped polysiloxane (10).…”
