“…Techniques like ink-jet printing, self-assembly, nanowire decorated surface-enhanced metallic electrodes and large-scale soft-lithography protocols could be further confi gured to precisely structure grid-like or interdigit electrodes for superior performance transparent energy storage sources. [ 409,[453][454][455][456][457][458][459] Various forms of transparent electrodes have been also proposed in the literature. Even if a transparent full cell was not always realized, the developments on separate components could serve as a basis for building-up transparent full cells.…”

“…Hence PTMA (as well as other polymer-based battery materials) can be solution processed, the production scale-up could be envisioned using traditional printing schemes or by exploring emerging self-assembly opportunities. [ 113,409,462,463 ] Energy storage devices with a smart human-machine interface can be obtained by further incorporating electrochromic materials into battery electrodes. Electrochromism is the phenomenon of reversible color or more generally, optical properties change, in response to an applied voltage.…”

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...

“…However, they do have some glaring drawbacks, including heat issues, the presence of rare and toxic elements, and scale-up technical problems, which limit their practical applications. [1] In the past few years, organic cathode materials including conducting polymers, [2][3][4][5] organosulfur compounds, [6][7][8][9][10][11][12][13][14][15] carbonyl derivatives, [16][17][18][19][20][21][22][23][24] organic radical polymers, [25][26][27][28][29][30] and some other redox-active molecules [31][32][33][34][35][36][37] have been explored intensively.

Abstract:Two new organometallic copolymers (PVFVM1 and PVFVM1-1) bearing different molar ratios of ferrocene and triphenylamine pendants were successfully designed and synthesized as cathode active materials for organic-battery applications. Their structural and thermal characteristics were determined by 1 H NMR spectroscopy, Fourier transform infrared (FTIR) spectroscopy, size exclusion chromatography (SEC), and thermogravimetric analysis (TGA). Cyclic voltammograms of the as-prepared polymers show that the electrochemical reactions

“…Some systems, in particular metallopolymers, were often utilized as networks and synthesized from two compounds, resulting in weakly soluble systems. Thus, the manufacturing of these systems needs to be improved [259][260][261]. A further challenge is the improvement in the mechanical properties of very good self-healing systems.…”

Supramolecular polymers are an intriguing class of materials with dynamic behavior as a result of the presence of non-covalent bonds. These bonds include hydrogen bonds, metallopolymers, ionomers, host-guest as well as π-π interactions. The strength of these supramolecular bonds can be tuned by varying the binding motifs. Their reversible and dynamic character can be utilized to engineer self-healing polymers. This review briefly presents the preconditions for design of self-healing polymers and summarizes the development of supramolecular self-healing polymers based on various non-covalent interactions. Furthermore, challenges and perspectives for the understanding of self-healing mechanisms and the preparation of novel materials with enhanced properties are discussed.
