“…The previous reports usually place emphasis on the preparation of single energy conversion or storage devices, and then combine them with commercial energy storage or conversion device if needed. [34][35][36][37] As shown in Figure 2A, laser-assisted microsupercapacitors array can be charged by commercial solar cell and then power LED. 36 In addition, the paper-based microsupercapacitors (Figure 2B) fabricated via templating and imprinting strategy can store the energy generated by wind turbines.…”

“…Initially, the simplest and easiest method to combine the energy conversion and storage devices is to connect two separate device units via external circuitry, which allows the converted energy to be stored and available on demand. The previous reports usually place emphasis on the preparation of single energy conversion or storage devices, and then combine them with commercial energy storage or conversion device if needed 34–37 . As shown in Figure 2A, laser‐assisted microsupercapacitors array can be charged by commercial solar cell and then power LED 36 .…”

The vigorous development in the field of energy conversion and storage devices directly contributes to the full utilization and convenient use of clean energy. However, some drawbacks of independent energy conversion and storage devices, including unstable, insufficient energy output and dependence on external power supply, are difficult to overcome by self‐optimization, thus, hindering their further development and direct application. Coincidentally, the combination of above two devices can solve these problems, which conforms to their intrinsic needs for development. At the same time, the pursuit of portability and miniaturization also promotes the development of the power system toward a highly integrated direction. Therefore, we introduce several integration modes of energy conversion and storage systems, with emphasis on all‐in‐one power system, possessing the highest integration in this review. From the aspect of device configuration, working mechanisms and their performances, the all‐in‐one power systems based on different energy sources (e.g., mechanical, solar, thermal, and chemical energy) are discussed and analyzed. Finally, the design strategies are summarized and the potential development directions in the future are proposed. This review aims to provide a comprehensive overview of highly integrated energy conversion and storage system, and seeks to point out the opportunities and orientations of future research in this field.

“…In this section, we will formulate (and qualitatively compare with published experiments) a simple model for the description of the configuration, which has been mostly studied experimentally up to date. Although some elementary expressions for basic electrokinetic phenomena of streaming potential and streaming current in this context were considered previously [16,18,28,29,47,48], no attempts to formulate a consistent model have been made. The configuration is schematically represented in Fig.…”

“…From the context, one can conclude that zeta-potentials were determined (probably using commercial instruments) from electrophoretic mobility (often in distilled water) of nanoparticles used to prepare the nanoporous films. Only in one study [48], it is explicitly stated that zeta-potential was determined from measurements performed with ELSZ-2000, Otsuka Electronics Co. instrument, and this presumably was done for assembled porous films (made of MoS2 and/or MoS2+SiO2 in this case) in DI water. However, as discussed below, interpretation of electrokinetic measurements with porous films requires special procedures, which were not implemented in [48].…”

Water-induced electricity generation as an emerging novel sustainable energy harvesting technology has become a hot research topic recently. Here, we develop a ceramic (SiO2) nanofiber-based water-induced electric generator via the sol–gel electrospinning technique, followed by calcination, which exhibits superior water-induced electricity generation property with significant softness. This superior performance of the SiO2 nanofiber-based generator may be attributed to two aspects: the electrokinetic effect generated by water evaporation force and the ion gradient formed between the top and bottom electrodes. The SiO2 nanofiber-based generator is capable of supplying a continuous voltage and current output of 0.48 V and 0.37 μA, respectively, without weakening after 500 times of bending. Moreover, the high voltage and current output generated by the water-induced generator can be realized in series or parallel and has practical applications, such as in a commercial digital calculator. This environmentally friendly generator, with its low cost, provides great potential for future green energy utilization and opens up new possibilities for portable electronics.
