Abstract:Porous carbon materials have played an indispensable role in electrochemical energy storage devices. This review introduced the physical and chemical properties as well as the common synthesis methods of oxygen-rich porous carbon materials. Besides, combining with the recent related progress in the fields of supercapacitors and lithium/sodium ion batteries, it discussed the action mechanism of oxygen functional groups during energy storage, and pointed out the mutual restriction of high specific capacity and high conductivity of oxygen-rich porous carbons when used in electrode materials. Moreover, it put forward that the reasonable design of types and amounts of oxygen functional groups in porous carbon materials could provide abundant redox active sites and enhance electrolyte affinity, and thus significantly promote energy density of porous carbon electrode materials, while maintaining original electrochemical stability. Finally, it proposed some important aspects for the future development of oxygen-rich porous carbon electrode materials mainly in the exploration of in situ characterization techniques and advanced structural and component design. © 2021, Chemical Industry Press Co., Ltd.
