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...

“…Besides the template fabricated through photolithography, the periodic or random arranged microspheres on substrate can also act as the template for the deposition of metal film with micrometer size holes, which allow the penetration of light . Thin film with the formation of cracks inside, in most cases, is normally regarded as poor quality.…”

Emerging novel metal electrodes not only serve as the collector of free charge carriers, but also function as light trapping designs in photovoltaics. As a potential alternative to commercial indium tin oxide, transparent electrodes composed of metal nanowire, metal mesh, and ultrathin metal film are intensively investigated and developed for achieving high optical transmittance and electrical conductivity. Moreover, light trapping designs via patterning of the back thick metal electrode into different nanostructures, which can deliver a considerable efficiency improvement of photovoltaic devices, contribute by the plasmon-enhanced light-mattering interactions. Therefore, here the recent works of metal-based transparent electrodes and patterned back electrodes in photovoltaics are reviewed, which may push the future development of this exciting field.

“…The diameter of colloidal spheres can also be precisely controlled in a wide range, spanning from several micrometers all the way to down to tens of nanometers. Uniquely, these colloidal spheres can be self‐assembled into 2D monolayers and 3D periodic multilayers, where they are subsequently utilized as the versatile masks (e.g., optical lens) to achieve fabrication templates by simple surface patterning onto underlying substrates, facilitating the construction of micro/nanostructure arrays with excellent tunability . Since then, these 2D monolayer colloidal crystals (MCCs) and 3D multilayers have attracted extensive attention for many of their further utilizations.…”

to potentially fabricate numerous hierarchical and periodic micro/nanostructure arrays in a large scale. [1][2][3][4][5] Importantly, these ordered micro/nanostructure arrays are essential active components for many technological applications, ranging from data storage, [6] solar cells, [7][8][9] plasmonics to functional coatings, and many others. [10][11][12][13][14][15] Combined with the recent advance in colloidal science, the colloidal spheres with uniform morphology and excellent disperse stability can be further realized by a number of methods, which include the suspension, [16,17] dispersion polymerization, [18,19] emulsion, [20,21] and Stöber techniques. [22] The diameter of colloidal spheres can also be precisely controlled in a wide range, spanning from several micrometers all the way to down to tens of nanometers. Uniquely, these colloidal spheres can be self-assembled into 2D monolayers and 3D periodic multilayers, where they are subsequently utilized as the versatile masks (e.g., optical lens) to achieve fabrication templates by simple surface patterning onto underlying substrates, facilitating the construction of micro/nanostructure arrays with excellent tunability. [23][24][25] Since then, these 2D monolayer colloidal crystals (MCCs) and 3D multilayers have attracted extensive attention for many of their further utilizations. For instance, by using the oxygen plasma and reactive ion etching (RIE) methods, the periodicity, the size, and the shape of individual spheres of MCCs are accurately controlled. [26,27] With further modification, etching, and decoration, the MCCs can be exploited as either the masks for metal catalyst deposition to generate hierarchical and periodic nanostructures on underlying substrates, or the templates for the growth of patterned nanostructures. [28,29] Furthermore, these MCCs can also be utilized as optical lens to construct the periodic nanostructures with photosensitive materials, broadening the preparing routes of hierarchical and periodic nanostructures. [30] In order to prepare the periodic nanostructures, the fabrication process, including the self-assembly of MCCs, the morphological modification of MCCs, and the functionalized decoration, is commonly referred as the nanosphere lithography (NSL). [31][32][33] As compared with conventional lithographic techniques, such as photolithography, [34,35] electron beam lithography, [36] and focused ion beam lithography, [37] NSL can distinctively reduce the manufacturing cost and complexity, The current research status on the self-assembly of colloidal spheres for the fabrication of various hierarchical and periodic nanostructures is summarized, in which these structures exhibit unique properties for different technological applications in plasmonics, surface-enhanced Raman scattering, solar cells, and others. The fundamentals of colloidal self-assembly are first introduced. After which, the functions of the obtained monolayer of colloidal spheres (e.g., nanosphere monolayer) to act as the patterned mask for the subsequent ...
