“…[ 280 ] Similarly, Sharma et al designed large area, rolled-up nanomembrane-based capacitor arrays by combining bottom-up and top-down fabrication methods. [ 308 ] Considerable scale-up was achieved, enabling parallel fabrication of more than 1600 devices on a 4-inch wafer. As mentioned by the authors, the fabricated electrostatic rolled-up ultra-compact energy-storage elements have a large potential in powering various autonomous microsystems.…”

all need to be used in conjugation with an energy storage system to provide smooth power leveling. Currently, electrochemical energy storage systems are by far the most optimal solutions for powering a broad range of technologies, expanding from compact and light-weighted portable electronic devices to stationary gridscale energy storage applications. [3][4][5][6] These energy storage devices (batteries and supercapacitors) store the available electrical energy in the form of chemical energy and release it whenever needed, by simply reversing the electrochemical reaction. [7][8][9][10][11] Among various available battery chemistries, lithium batteries and supercapacitors are the most promising technologies. [ 7,[9][10][11][12][13][14][15][16][17][18][19][20] Ever since the realization of the fi rst electrochemical energy storage cell by Alessandro Volta (end of 17th century), the working principle and its function has changed very little. [ 21,22 ] Basically, two redox couples (or charge storage electrodes), electrically and physically separated, are bridged by an ion conducting medium to constitute an electrochemical cell. This holds true also for modern Li-ion batteries, although the chemistry involved is much more complex. During operation, the electrons are transferred through an external circuit while ions shuttle through the electrolyte to counterbalance the depleted charge at the electrodes. [ 23 ] So far, much of the effort has been directed towards improvement of the energy and power characteristics by downsizing the active components, re-engineering the current collectors and separators, as well as fi ne-tuning the Batteries have become fundamental building blocks for the mobility of modern society. Continuous development of novel battery chemistries and electrode materials has nourished progress in building better batteries. Simultaneously, novel device form factors and designs with multi-functional components have been proposed, requiring batteries to not only integrate seamlessly to these devices, but to also be a multi-functional component for a multitude of applications. Thus, in the past decade, along with developments in the component materials, the focus has been shifting more and more towards novel fabrication processes, unconventional confi gurations, and additional functionalities. This work attempts to critically review the developments with respect to emerging electrochemical energy storage confi gurations, including, amongst others, paintable, transparent, fl exible, wire or cable shaped, ultra-thin and ultra-thick confi gurations, as well as hybrid energy storage-conversion, or graphene-incorporated batteries and supercapacitors. The performance requirements are elaborated together with the advantages, but also the limitations, with respect to established electrochemical energy storage technologies. Finally, challenges in developing novel materials with tailored properties that would allow such confi gurations, and in designing easier manufacturing techniques that can be widely adopted ar...

“…The capacity gradually decreases with increasing current density from a low current rate of 0.1 A g −1 to a high current rate of 25 A g −1 and the capacity reversibly recovers to ≈1000 mA h g −1 once the current rate goes back to 0.5 A g −1 . In addition to the improved stability, the energy storage device based on rolled‐up nanomembrane also has the advantages of miniaturization of the volume and reduction of the footprint area …”

Nanoscience and nanotechnology offer great opportunities and challenges in both fundamental research and practical applications, which require precise control of building blocks with micro/nanoscale resolution in both individual and mass-production ways. The recent and intensive nanotechnology development gives birth to a new focus on nanomembrane materials, which are defined as structures with thickness limited to about one to several hundred nanometers and with much larger (typically at least two orders of magnitude larger, or even macroscopic scale) lateral dimensions. Nanomembranes can be readily processed in an accurate manner and integrated into functional devices and systems. In this Review, a nanotechnology perspective of nanomembranes is provided, with examples of science and applications in semiconductor, metal, insulator, polymer, and composite materials. Assisted assembly of nanomembranes leads to wrinkled/buckled geometries for flexible electronics and stacked structures for applications in photonics and thermoelectrics. Inspired by kirigami/origami, self-assembled 3D structures are constructed via strain engineering. Many advanced materials have begun to be explored in the format of nanomembranes and extend to biomimetic and 2D materials for various applications. Nanomembranes, as a new type of nanomaterials, allow nanotechnology in a controllable and precise way for practical applications and promise great potential for future nanorelated products.

the aim to circumvent the intermittency of these dynamic resources and provide power supply on demand, energy storage systems that can effectively store the elec trical energy are strongly demanded. [5][6][7] Among numerous electrical energy storage (EES) devices available today, lithium batteries, capacitors, and super capacitors are particularly appealing owing to their large capabilities of storing energy with long service lifetime. [8,9] In recent years, with the rapid development of mate rial science and nanotechnology, energy storage devices with enhanced performance have been realized, [2,[6][7][8][9][10] and they have emerged as the dominant power sources for portable electronics in modern society. Despite the advances already achieved, per formance of these EES devices still needs to be further improved in order to meet the higher requirements of future systems, ranging from microelectrochemcial sys tems (MEMS) to electrical transportation systems like electric vehicles.The development of the electrode mate rials is essential for the improvement of high performance EES systems. [11,12] Noticeably, nanomateirals derived from rolledup nanotechnology have attracted world wide interest recently, and remarkable progress has been made when introducing this technology into the design of energy storage devices. [13][14][15][16][17][18][19][20][21][22][23][24][25] In particular, nanostructures prepared by rolledup nanotechnology offer controllable surface area, short charge diffusion distance, and large freedom for volume change during charge/discharge cycles. In this sense, rolledup nano structured materials can be expected to improve the energy den sity, life cycle, and rate capability of lithiumbased batteries. In addition, the high compatibility with lithography and physical vapor deposition techniques makes rolledup nanotechnology suitable for labonachip EES device fabrication as well as other tremendous integrative devices applications. [26][27][28][29][30] In this report, we focus on the recent progress of using rolledup nanostructured materials as electrodes to develop advanced EES devices, including Liion batteries (LIBs) and LiO 2 batteries. In addition, single tube based EES micro devices as diagnostic electrochemical probes for basic mechanistic investigations are summarized. Notable progress of introducing rolledup nanotechnology into the design of scalable and ultra compact electrostatic capacitors with superior performance is also reviewed. Finally, future trends of applying rolledup nanotechnology to other potential applications, such as scalable Energy storage devices, acting as complementing units for renewable energy sources, play a key role in modern society, and they serve as the dominant power supply for most portable electronics. At the heart of the development of next-generation energy storage devices lies the exploration of intrinsic material properties, architectural design and fabrication methods.
