Functional Inks for Printable Energy Storage Applications based on 2 D Materials

Abstract

Ubiquitous portable electronics and the ever‐growing internet‐of‐things have necessitated the emergence of high‐end miniaturized devices as well as associated sophisticated printing technologies. With excellent solution processability and tunable electronic properties, 2 D 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 challenges that we are facing of the developments of 2 D 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 least, we also propose the perspectives on the development of 2 D materials‐based inks for energy‐storage applications.

Transparent Electrodes for Energy Storage Devices

“…To meet the development of miniaturized electronics, fabricating TESEs through advanced technologies such as inkjet printing and screen printing will extend their applications in miniaturized products and integrated circuits. [102][103][104] Pioneering works have been successively done by Zhou, Huang, and Östling's groups. [40,47,86] We do believe that printable transparent energy-storage devices will arouse considerable interest in the future.…”

Printed aerogels: chemistry, processing, and applications

“…The matching of ink rheological properties specific to printing methods determines their printability. 187 These rheological properties as well as the microstructure and final characteristics of the printed aerogels can be controlled by the process parameters in the ink preparation process, such as the ink composition, raw material morphology, and formulation. Based on different gelation principles in inks, we divide the discussion in this section into molecule-derived and nanomaterial-derived pathways.…”

A Review on Materials and Technologies for Organic Large‐Area Electronics

“…For instance, in the majority of the cases, the resulting morphologies are less uniform and the low concentration of the inks requires more printing passes (for better conductivity), thus making the inkjet printing time‐consuming. [ 47,110 ]…”

“…[ 350 ] It has also empowered the manufacture of integrative devices such as current collectors, electrolytes, and packaging alternatives. [ 110 ]…”
