Flexible transparent portable electronic products provide substantial support for the rapid development of the intelligent era. Flexible transparent supercapacitors (FTSCs) are considered the most promising energy storage devices due to their exceptional electrochemical performance, outstanding mechanical flexibility, and high optical transmittance. However, it is difficult to balance their mechanical flexibility and optical transmittance. The key to reconciling the contradiction is to fabricate flexible transparent conductive electrodes (FTCEs) with excellent mechanical flexibility and optical transmittance by combining the characteristics of manufacturing technologies and electrode materials. In this review, the characteristics of advanced FTCEs manufacturing technologies and their applications in FTSCs are systematically summarized. First, the device structure, working mechanism, and basic performance of FTSCs are briefly introduced. Second, the manufacturing characteristic and principle of different FTCEs preparation technologies are mainly described, including vacuum filtration, coating, deposition, printing, and layer‐by‐layer assembly. Next, the device structure and design principle of multifunctional FTSCs are demonstrated in detail. Finally, the challenges and prospects of applying FTCEs manufacturing technology to construct FTSCs are proposed.

The rapid development of miniaturized electronic devices has greatly stimulated the endless pursuit of high-performance on-chip micro-supercapacitors (MSCs) delivering both high energy and power densities. To this end, an advanced three-dimensional (3D) microelectrode architecture design offers enormous opportunities due to high mass loading of active materials, large specific surface areas, fast ion diffusion kinetics, and short electron transport pathways. In this review, we summarize the recent advances in the rational design of 3D architectured microelectrodes including 3D dense microelectrodes, 3D nanoporous microelectrodes, and 3D macroporous microelectrodes. Furthermore, the emergent microfabrication strategies are discussed in detail in terms of charge storage mechanisms and structure− performance correlation for on-chip MSCs. Finally, we conclude with a perspective on future opportunities and challenges in this thriving field.

“…Micro-supercapacitors (MSCs) emerged as potential energy storage devices complementing microbatteries to power ubiquitous sensor networks needed to foster the development of IoT [3]. Due to the fast surfaceconfined reactions involved in double-layer or pseudocapacitive charging, MSCs show highpower delivery performance through fast charge/discharge along with excellent cycling stability [4][5][6][7][8]. However, these reactions provide low energy density which prevents their largescale adoptability in real device applications.…”
