“…The results showed that prints with a reflective optical density of more than 1.0 were obtained with excellent tonal reproduction ( Figure 4 b). Yuan et al [ 107 ] also developed a stabilized biochar-based ink made from fruit peels that can be integrated on different flexible substrates by SPE or program-controlled writing methods. This suggests that replacing fossil fuel charcoal with biochar for printing materials is a promising avenue, but more research is still needed to lay the theoretical foundation.…”

Biochar is a solid material enriched with carbon produced by the thermal transformation of organic raw materials under anoxic or anaerobic conditions. It not only has various environmental benefits including reducing greenhouse gas emissions, improving soil fertility, and sequestering atmospheric carbon, but also has the advantages of abundant precursors, low cost, and wide potential applications, thus gaining widespread attention. In recent years, researchers have been exploring new biomass precursors, improving and developing new preparation methods, and searching for more high-value and meaningful applications. Biochar has been extensively researched and utilized in many fields, and recently, it has also shown good industrial application prospects and potential application value in the printing field. In such a context, this article summarizes the typical preparation and modification methods of biochar, and also reviews its application in the printing field, to provide a reference for future work.

“…A screen printing method was also applied to make solid-state flexible micro-supercapacitors with 3D boron carbon nitride microspheres (made via hydrothermal and annealing techniques), with an areal capacitance of 41.6 mF/cm 2 [195]. A simple fabrication process with screen printing was also employed to make solid-state integrated micro-supercapacitor arrays with porous activated biochar (Figure 13), which exhibited an areal capacitance of 116 mF/cm 2 and a high areal energy density of 9.3 µWh/cm 2 [196].…”

The very fast evolution in wearable electronics drives the need for energy storage micro-devices, which have to be flexible. Micro-supercapacitors are of high interest because of their high power density, long cycle lifetime and fast charge and discharge. Recent developments on micro-supercapacitors focus on improving the energy density, overall electrochemical performance, and mechanical properties. In this review, the different types of micro-supercapacitors and configurations are briefly introduced. Then, the advances in carbon electrode materials are presented, including activated carbon, carbon nanotubes, graphene, onion-like carbon, and carbide-derived carbon. The different types of electrolytes used in studies on micro-supercapacitors are also treated, including aqueous, organic, ionic liquid, solid-state, and quasi-solid-state electrolytes. Furthermore, the latest developments in fabrication techniques for micro-supercapacitors, such as different deposition, coating, etching, and printing technologies, are discussed in this review on carbon electrode-based micro-supercapacitors.
