Ubiquitous portable electronics and ever-growing Internet of Things have necessitated the emergence of high-end miniaturized devices as well as associated sophisticated printing technologies. With excellent solution processibility and tunable electronic properties, two-dimensional (2D) materials stand as a promising candidate for functional inks that are readily printable for energy-storage devices. In this review, we outline the significance, status and the challenges that we are facing of the developments of 2D materials-based functional inks. Then, general ink formulation and basic knowledge of printing techniques together with their rheological requirements and enabled applications in energy storage are introduced, providing guidelines for developing inks that match well with the present printing techniques. Last but not the least, we also propose the perspectives on the development of 2D materials-based inks for energy-storage applications.
