“…Accurately controlled superthin electrode fi lms can be easily prepared with a template method. [ 102,110,135,[141][142][143] By directly growing graphene fi lms onto a pre-stretched substrate, a stretchable electrode was obtained with an optical transmittance of up to 72.9% at a wavelength of 550 nm, low sheet resistance and desirable mechanical compliance ( Figures 4 d and e). [ 139 ] The effi cient contact between the Au current collector and the in-situ grown MnO 2 nanosheet provided excellent electrochemical properties including high capacitance of 4.72 mF cm −2 with high rate capability besides maintaining a high transparency and fl exibility.…”

LIBs generally meet the requirement of high energy density, while SCs are typically used for high power density based on the different working mechanisms. Some efforts are also made to achieve both high energy density and high power density by synthesizing functional materials and designing novel structures. [5][6][7][8][9][10][11][12][13][14][15][16][17][18] These advancements have been summarized in the other reviews and will not be covered here. However, the traditional LIBs and SCs that appear in a rigid bulky or planar structure cannot satisfy next-generation electronic devices. For instance, it is difficult for them to meet the requirements of being small, lightweight, fl exible, weaveable, adaptable, and self-powering from wearable electronic devices.Therefore, besides the continuous efforts to increase the energy storage capability, considerable interest has also been attracted to introducing smart components into conventional materials, and designing new structures aimed at more functions. [19][20][21][22][23][24][25][26][27] On one hand, fl exible, stretchable, transparent, responsive, and self-healing properties are integrated into LIBs and SCs, in addition to storing energy, on the basis of the use of functional materials. On the other hand, the LIBs and SCs have been also integrated with various energy harvesting devices to realize the desired self-powering capability. To better achieve the practical application of the above energy storage devices, miniaturized structural design such as fi ber-shaped LIBs and SCs has boomed over just a few years, and more attention is being paid to weaving them into powering fabrics.Here, recent progress in developing high-performance energy storage devices by an integration strategy is highlighted to satisfy the next-generation electronics. Integration with more functions based on advanced materials is fi rst discussed for multifunctional devices. Integration with energy harvesting devices is then provided for self-powering devices. The integration of LIBs and SCs into smart fabrics is followed to refl ect a new booming direction in the energy storage industry. The current challenges and developing directions are fi nally summarized for future study. Integration at the Level of MaterialsHigh energy and power densities have been extensively explored since the discovery of LIBs and SCs, while the incorporation of more functions has become increasingly important, particularly Energy storage devices are arousing increasing interest due to their key role in next-generation electronics. Integration is widely explored as a general and effective strategy aiming at high performances. Recent progress in integrating a variety of functions into electrochemical energy storage devices is carefully described. Through integration at the level of materials: fl exible, stretchable, responsive, and self-healing devices are discussed to highlight the state-ofthe-art multi-functional electronics. Through the integration at the level of devices, the incorporation of photovoltaic and piez...

“…The various buckypaper production methods can be divided into solution strategies, such as vacuum filtration [18], the spray method [19], the casting method [20], and the printing method [21], and dry strategies that do not use a solvent, such as the floating catalyst chemical vapor deposition process [22] and drying spinning [23]. Buckypaper can be used in various fields, such as filtration and distillation membranes [24], actuators [25] and supercapacitors [26], as well as thermally and electrically conductive materials [27]. …”

To investigate the effect of continuous multi-walled carbon nanotubes (MWCNTs) on the thermal and mechanical properties of composites, we propose a fabrication method for a buckypaper-filled flexible composite film prepared by a two-step process involving buckypaper fabrication using vacuum filtration of MWCNTs, and composite film fabrication using the dipping method. The thermal conductivity and tensile strength of the composite film filled with the buckypaper exhibited improved results, respectively 76% and 275% greater than those of the individual MWCNT-filled composite film. It was confirmed that forming continuous MWCNT fillers is an important factor which determines the physical characteristics of the composite film. In light of the study findings, composite films using buckypaper as a filler and polydimethylsiloxane (PDMS) as a flexible matrix have sufficient potential to be applied as a heat-dissipating material, and as a flexible film with high thermal conductivity and excellent mechanical properties.
