“…57 The main function of the polymeric separator in these electrochemical energy devices is to provide electrical insulation (to avoid short circuit) and ionic conductivity (to provide ion-transportation pathways). [58][59][60] In contrast, piezoelectric nanogenerators came under energy harvesting devices that convert mechanical energy into electrical energy. 61,62 At first, the concept of piezoelectric nanogenerators for explicit transduction of mechanical into electrical energy was initially illustrated in 2006 by Wang 63 using the deflection of ZnO nanowires with conductive atomic force microscopy (AFM).…”

The increasing demand for wearable electronic devices has resulted in tremendous progress in research on energy harvesting and storage devices/ technologies. Energy storage devices require a power source to charge them, whereas energy harvesting devices require a storage compartment to store the harvested energy for sustainable delivery. Recently, a piezoelectrically driven self-charging supercapacitor power cell (SCSPC) was developed to harvest and store electrical energy in a solitary system to determine the potential impact of these two types of energy devices for wearable electronic applications. This review describes the recent advances in piezoelectric-driven SCSPCs in terms of device configuration, piezoelectric separator, electrolyte types, electrode materials, current collectors, and system integration. This review focuses specifically on the principles and mechanism of the self-charging process that occurred in the SCSPCs and the use of a promising piezo electrochemical spectroscopic tool to realize the piezo electrochemical energy transfer and storage process in the SCSPCs. Further, the current challenges and new perspectives for future developments in the emerging area of SCSPCs or integrated energy devices are discussed.

“…Ideal characteristics of a separator include high porosity, high permeability, good mechanical strength, high ionic conductivity, high thermal stability, etc. [42] The commonly used separator materials are non-woven fibers, polymers, rubber, and wood. In addition to preventing the device from short-circuiting, separator materials also store electrolytes in their pores and allow ions to move through them during the charging and discharging processes.…”

Emerging demands to achieve zero carbon emissions and develop renewable energy resources necessitate the development of appropriate energy storage systems. To achieve this, several alternatives to conventional energy storage devices, such as Li‐ion batteries or capacitors to more sustainable and scalable energy storage systems, are being explored. Supercapacitors, possess unique characteristics that include high power, long life, and environmental‐friendly design. They may be used to bridge the energy‐power gap between typical capacitors and fuel cells/batteries. Recently, structural supercapacitors being capable of storing electrochemical energy besides bearing mechanical load have caught the attention of researchers. As such, efforts have been made worldwide to study both the fundamental and applied aspects of structural supercapacitors. Further, the possibility of using construction materials for interdisciplinary applications is being studied because they are relatively cheap and easily available. Thus, construction materials can be considered as potential candidates for the development of structural supercapacitors. Herein an overview on the use of construction materials, such as Portland cement concrete, geopolymer concrete, and bricks, as a component of structural supercapacitors has been presented.

“…18 Electrolyte research has been primarily focused on improving the aforementioned properties. Another important but often neglected component of a supercapacitor is the separator 25 which electrically isolates the positive and negative electrodes while allowing ion transport through its pores. Its requirements include high electrical resistance, high ionic conductivity and low thickness while maintaining high mechanical integrity.…”
