“…It would be thus highly advantageous to get inspiration from biomimetic protocols to build better energy storage systems, and why not build hybrid bio-interfaced batteries, supercapacitors and other energy devices. [ 767,768 ] Direct interfacing is hardly conceivable because of incompatible chemistries involved in both type of systems. Yet pioneering advances are being already provided, for example, towards implantable bio-supercapacitors.…”

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...

“…Although schemes in high-frequency or ultrahigh-frequency wireless power transfer satisfy requirements in many important contexts (14,15), opportunities remain for approaches in local generation and/or storage of power in ways that retain overall stretchable characteristics at the system level. Reported approaches to the former involve harvesting based on piezoelectric (16,17), triboelectric (18), and thermoelectric (19) effects; the latter includes batteries (20)(21)(22) and supercapacitors (23,24) enabled by various unusual materials. Complete power management systems that offer both types of functionality, in an actively coordinated fashion and with robust, high-performance operation, represent an important goal.…”

Power supply represents a critical challenge in the development of body-integrated electronic technologies. Although recent research establishes an impressive variety of options in energy storage (batteries and supercapacitors) and generation (triboelectric, piezoelectric, thermoelectric, and photovoltaic devices), the modest electrical performance and/or the absence of soft, biocompatible mechanical properties limit their practical use. The results presented here form the basis of soft, skin-compatible means for efficient photovoltaic generation and high-capacity storage of electrical power using dual-junction, compound semiconductor solar cells and chip-scale, rechargeable lithium-ion batteries, respectively. Miniaturized components, deformable interconnects, optimized array layouts, and dual-composition elastomer substrates, superstrates, and encapsulation layers represent key features. Systematic studies of the materials and mechanics identify optimized designs, including unusual configurations that exploit a folded, multilayer construct to improve the functional density without adversely affecting the soft, stretchable characteristics. System-level examples exploit such technologies in fully wireless sensors for precision skin thermography, with capabilities in continuous data logging and local processing, validated through demonstrations on volunteer subjects in various realistic scenarios.solid-state lithium-ion battery | multijunction solar cell | stretchable electronics | energy management | wearable technology R ecent ideas in materials science and mechanical engineering establish strategies for integrating functionality enabled by hard forms of electronics with compliant interconnects and soft packages to yield hybrid systems that offer low-modulus, elastic responses to large strain deformations (1-4). Such stretchable characteristics are qualitatively different from those afforded by simple mechanical bendability; the consequences are important because such properties allow for intimate, long-lived interfaces with the human body, such as the skin (5, 6), heart (7), and the brain (8), and for development of unusual device designs that derive inspiration from biology (9, 10). Many impressive examples of the utility of these concepts have emerged over the last several years, particularly in the area of biomedical devices, where work in skin-mounted technologies is now moving from laboratory demonstrations to devices with proven utility in human clinical studies (11, 12) and even to recently launched commercial products (13). Although schemes in high-frequency or ultrahigh-frequency wireless power transfer satisfy requirements in many important contexts (14, 15), opportunities remain for approaches in local generation and/or storage of power in ways that retain overall stretchable characteristics at the system level. Reported approaches to the former involve harvesting based on piezoelectric (16, 17), triboelectric (18), and thermoelectric (19) effects; the latter includes batteries (20-22) and supercapa...

“…Furthermore, they found that a relatively simple molecule with shorter side chain than flavins, called lumiflavine (7,8,, had a theoretical capacity as high as 209.18 mA h g −1 , and its actually tested gravimetric capacity was 174.32 mA h g −1 , which was much higher than 105.88 mA h g −1 of riboflavin with enhanced stability. [117][118][119] Then, through the further molecular tailoring, the optimized pteridine-based active materials immobilized onto conductive scaffolds through non-covalent bonding showed excellent electrochemical performance, could deliver a gravimetric energy density up to 533 W h kg −1 within 1 h and 348 W h kg −1 within 1 min, as well as high cyclability retaining 96% of the initial capacity after 500 cycles at 10 A g −1 . [117][118][119] Clearly, these reports have shown that the biological energy metabolism and storage machineries can provide guidelines for the rational design of novel sustainable energy-storage systems beyond the conventional electrode materials.…”

Nature-inspired strategies have been proposed recently as novel and effective routines to address these challenges.(1) Specifically, the limited availability of mineral resources could hardly satisfy the booming requirement and subsequent production quantity of energystorage devices for long time, and will necessarily lead to their increasing price. [15,16] Moreover, the non-biodegradability of current energy-storage devices after their service lifetime will bring about tremendous electronic garbage. Thus, renewable, cheap and environment-friendly energy-storage related materials are greatly desired to substitute current components. [12,[17][18][19][20][21][22][23][24][25][26] In nature, its energy conversion and storage systems have been evolved for billions of years, and spawned highly efficient and well suited cellular respiration machineries in living organisms for external energy assimilation, metabolism and distribution. [27] In recent years, inspirations have been taken from nature to fabricate biomolecule-based electrode materials from renewable biomass. [28][29][30][31][32] For example, inspired by the electron shuttles functioning in extracellular electron transfer via reversible redox-cycling, man-made electrode materials with similar active functional groups have been explored. [33,34] In our newly reported work, supercapacitor employing redoxactive biomolecule as the faradic-type active material could even obtain a higher energy density than those of previous transition-metal-based supercapacitors. [35] (2) Another issue encountered by current energy-storage system arises from the laborious preparation processes of their energy-storage materials which usually adopt extreme conditions. In biological systems, assembly of complicated micro-organelles are precisely controlled with the aid of biotemplates. By mimicking the bio-assembly processes or utilizing appropriate biotemplates, facile preparation of energy-storage materials in mild conditions has been achieved. [36][37][38][39][40][41][42][43][44] (3) In rechargeable batteries and supercapacitors, the architecture of active materials always determines their cycle life and rate performance. [45][46][47][48] While the abundant examples of natural structures with known stableness, geometry configuration, surface wettability and mechanical property provide clues for rational design of nanostructured active materials with desired performance. [49][50][51][52][53][54][55][56][57][58][59][60][61][62][63] (4) What's more, nature-inspired routines are also useful for rational design of ideal binders Currently, tremendous efforts are being devoted to develop high-performance electrochemical energy-storage materials and devices. Conventional electrochemical energy-storage systems are confronted with great challenges to achieve high energy density, long cycle-life, excellent biocompatibility and environmental friendliness. The biological energy metabolism and storage systems have appealing merits of high efficiency, sophisticated regulation, clean and renewabil...
