There have been considered the problems of supercapacitors development related to the
enhancement of operating characteristics of such systems such as the specific energy sorage,
specific released energy, charging-discharging time, the ability to to stand the maximum charge-
discharge cycling times without lowering the stored energy etc. One of the approaches to the
solution of the above-listed problems relates to the usage of graphene and related materials as
electrodes for supercapacitors. The presented article reviews works addressed to the investigation
of graphene-based materials with the aim of their usage in supercapacitors. A special attention is
paid to hybrid systems in which graphene-based materials are used in combination with metal
oxides. Such systems called pseudocapacitors possess higher operation characteristics in comparison with conventional supercapacitors due to the possibility to perform chemical processes
on the interface between the electrode and electrolyte.
