ABSTRACT
The application of 3D technology (namely converting a digital design into a physical 3D object) for battery development attracts increased research attention in both academic and industrial spheres. Such an interest is linked with the absence of limitations (e.g., controlling the electrode geometry and architecture) which are common for traditional methods of battery fabrication. 3D printing makes it possible to create a next-generation of electrodes that combine a developed porous architecture with a flexible design and shape. In this aspect, the elaboration of graphene-based 3D-printed batteries is of particular interest due to the unique set of properties of such materials, including conductivity and mechanical flexibility. In the present review, numerous ways of fabrication of graphene-based electrodes by 3D printing are considered to reveal the architecture/performance relationship.
