Flexible supercapacitors (FSCs) can be power sources for the next generation of flexible and wearable electronic devices. Recent breakthroughs in nanotechnology have opened new opportunities in the energy industry to improve the performance of FSCs by providing high energy density, high power density, and excellent flexibility. Due to their higher surface area, larger contact area between electrode and electrolyte, and shorter ion‐diffusion pathways, low‐dimensional materials with a wide variety of morphologies play a key role in improving the performance of FSCs. Especially nanostructured transition metal oxides (TMOs) are of great interest for the application of SCs due to their superior specific capacitance, high energy density, high redox reversibility, easy availability, and environmental safety. However, the low electrical conductivity, low power density, poor cycle stability, and rigid properties of TMOs have limited their wide applications for FSCs. Therefore, the fabrication of nanostructured TMO‐based composites with conducting carbon, polymers, and other materials with large surface areas, pore and layer structures, etc., improves the electrical and mechanical properties. This review provides a brief overview of the current developments in 2D and 3D TMO‐based nanomaterials and their preparation techniques, design, structure, and fundamental understanding of nanoscale capacitive behavior for advanced flexible energy storage applications.

“…3D printing technology is believed to fabricate lightweight, flexible, thin, and high-performance wearable devices. [74] Hydrogels/aerogels, colloidal gels, and liquid polymer composites are the preferred candidates for printing 3D structures owing to their adjustable viscoelastic properties under different conditions. In addition, the exceptional active surface area, high porosity, and electrical conductivity of several hydrogels/ aerogels make them competitive materials for supercapacitors.…”

Recently, three‐dimensional (3D) printing has become a research focus point and has evolved as a powerful tool for manufacturing complex objects for advanced technology platform designs. Herein, we review the current state‐of‐the‐art 3D‐printed hydrogels and aerogels for wastewater treatment and energy storage applications. Several 3D printing methods such as direct ink writing, digital light processing, and fused filament fabrication have been discussed. Among these, direct ink writing is the most employed 3D printing technique for hydrogels and aerogels. We systematically investigated the most important results of several 3D‐printed hydrogels and aerogels for adsorption, photocatalysis, membrane filtration, and desalination for wastewater treatment, supercapacitors, and batteries in energy storage applications. Finally, we conclude our understanding with the prospect of future opportunities in this field using 3D‐printed hydrogels and aerogels for wastewater treatment and energy storage applications. In summary, the fundamental knowledge of 3D printing and critical assessment of the key literature on 3D‐printed hydrogels and aerogels and their applications in water treatment and energy storage will provide guidance for future studies in smart materials and waste management aspects of sustainability.
