HIGHLIGHTS• The progress of nanogenerator-based self-charging energy storage devices is summarized.• The fabrication technologies of nanomaterials, device designs, working principles, self-charging performances, and the potential application fields of self-charging storage devices are presented and discussed.• Some perspectives and problems that need to be solved are described.ABSTRACT One significant challenge for electronic devices is that the energy storage devices are unable to provide sufficient energy for continuous and long-time operation, leading to frequent recharging or inconvenient battery replacement. To satisfy the needs of next-generation electronic devices for sustainable working, conspicuous progress has been achieved regarding the development for nanogenerator-based self-charging energy storage devices. Herein, the development of the self-charging energy storage devices is summarized. Focus will be on preparation of nanomaterials for Li-ion batteries and supercapacitors, structural design of the nanogenerator-based self-charging energy storage devices, performance testing, and potential applications.Moreover, the challenges and perspectives regarding self-charging energy storage devices are also discussed.

“…Further, the SCPC device demonstrated by Parida et al using polymethyl methacrylate/LiClO 4 as an electrolyte which showed a self-charging of about 75 mV in 40 s using poly vinylidene fluoride-co-trifluoroethylene (PVDF-TrFE) as the separator with carbon nanotubes as energy storage electrodes. [26] Among the electrode materials, MnO 2 , carbon, carbon nanotube, NiCoOH/CuO-Cu, and rGO/CuO are used in SCPC device, and it is well known that the mechanism of charge storage in these materials is different such as electric double layer capacitance, pseudocapacitance, and Faradic capacitance. Recently, Maitra et al reported SCPC in the asymmetric configuration using a natural bio-piezoelectric separator (derived from fish swim bladder) which self-charged up to 150 mV in 80 s. [24] It is clearly evident from these studies that still a lot of efforts are highly needed to improve the selfcharging performance of the integrated device which highly depends on the piezo-electrochemical energy conversion process.…”

compartments, namely, (i) energy harvesting and (ii) energy storage in which the former generates the energy while the latter is used to store the generated energy. [6,7] Renewable energy sources such as solar, wind, hydropower, mechanical energy (piezoelectric/triboelectric nanogenerator), and electrochemical energy (fuel cells) are used as energy harvesting system, whereas batteries and supercapacitors are used as energy storing system in the design of selfcharging power system. [8][9][10][11][12] Renewable power source based self-charging power system such as coupling of the solar cell/ photovoltaics with the electrochemical energy storage are commercialized for making use of the photon energy into useful energy. [13,14] Hitherto, the utilization of biomechanical energy for the selfcharging system is still in research level, and further efforts are needed to be undertaken for practical applications. The concept of self-charging and/or self-powered system for harvesting and storing mechanical and/or biomechanical energy becomes plausible after the research findings of Wang and co-workers for the first time when they designed a self-powered system using nanogenerator (NG) and supercapacitor in 2012. [2] Up to date two different types of self-charging power cells have been reported such as (i) external powering and (ii) internally integrating the system. [8,[15][16][17] In the former case, the mechanical energy harvester is externally connected to the energy storage device using a rectifier, whereas the latter uses an all-in-one integrated system which will be beneficial for several applications in portable and wearable devices due to their miniaturized size. [18,19] The pulsating alternating current output of nanogenerator is the major concern for the practical application of NG based self-charging power cells (SCPCs) due to their low energy conversion efficiency. [7,20] Therefore, the design and development of high-performance self-charging power cell with high energy conversion efficiency are highly essential. In this scenario, integrated self-charging supercapacitor power cell (SCSPC) utilizing supercapacitor as energy storage device attracts much attention compared to batteries mainly due to the fast charging rates of a capacitive type electrode; it can scavenge/store the piezo-electrochemically generated Self-charging supercapacitor power cell (SCSPC) received much attention for harvesting and storing energy in an integrated device, which paves the way for developing maintenance free autonomous power systems for various electronic devices. In this work, a new type of SCSPC device is fabricated comprising 2D molybdenum di-selenide (MoSe 2 ) as an energy storing electrode with polyvinylidene fluoride-co-hexafluoropropylene/ tetraethylammonium tetrafluoroborate (PVDF-co-HFP/TEABF 4 ) ion gelled polyvinylidene fluoride/sodium niobate (PVDF/NaNbO 3 ) as the piezopolymer electrolyte. The fabricated SCSPC delivers a specific capacitance of 18.93 mF cm −2 with a specific energy of 37.90 mJ cm −2 at a specific power...
