“…Surface etching is an efficient route to increase the effective surface area of the metallic foil and its capacitance in AECs. [57,58] Inspired by this, surface etching was also conducted in our work by sonicating Ni foil in 6 m HCl prior to catalyst coating, aiming to increase the effective ion transport paths and surface area of the electrode material (etching method is presented in Note S2 in the Experimental Section, Supporting Information). The effect of etching time on the surface roughness of Ni foil was studied, as shown in Figure S2, Table S1 and discussions in the Supporting Information.…”

friction into direct current (DC) signal, [1,2] or bypassing the main power to serve as temporary backup for suppressing the high-frequency noise caused by voltage decline or switching of the components in the circuit. The commonly used filtering device serving these purposes are electrolytic capacitor, such as aluminum electrolytic capacitor (AEC), which is the bulkiest component in the integrated circuit. [3] Therefore, reducing the size of electrolytic capacitor is crucial for achieving higher integration level and the miniaturization of wearable/portable electronics. Although the miniaturization of active components, such as transistors and sensors, have been extensively studied, the small-scale design of the AEC encounters a major obstacle since it suffers from low volumetric specific energy density (E v). [1-3] This challenge makes the AEC increasingly incompatible with the rapid development of miniaturized wearable and portable electronics.

“…Fig. 5d shows that the Al electrolytic capacitor gives a constant output voltage of 12.1 V. Al electrolytic capacitors are frequently used in electronics applications if large energy storage capability is required (Ebel, 2023) and leakage current is not an important factor (Gudavalli and Dhakal, 2018).…”

This paper reviews energy storage systems, in general, and for specific applications in low-cost micro-energy harvesting (MEH) systems, low-cost microelectronic devices, and wireless sensor networks (WSNs). With the development of electronic gadgets, low-cost microelectronic devices and WSNs, the need for an efficient, light and reliable energy storage device is increased. The current energy storage systems (ESS) have the disadvantages of self-discharging, energy density, life cycles, and cost. The ambient energy resources are the best option as an energy source, but the main challenge in harvesting energy from ambient sources is the instability of the source of energy. Due to the explosion of lithium batteries in many cases, and the pros associated with them, the design of an efficient device, which is more reliable and efficient than conventional batteries, is important. This review paper focused on the issues of the reliability and performance of electrical ESS, and, especially, discussed the technical challenges and suggested solutions for ESS (batteries, supercapacitors, and for a hybrid combination of supercapacitors and batteries) in detail. Nowadays, the main market of batteries is WSNs, but in the last decade, the world’s attention has turned toward supercapacitors as a good alternative of batteries. The main advantages of supercapacitors are their light weight, volume, greater life cycle, turbo charging/discharging, high energy density and power density, low cost, easy maintenance, and no pollution. This study reviews supercapacitors as a better alternative of batteries in low-cost electronic devices, WSNs, and MEH systems.
