“…In some examples, zinc foil (ca. 2.3 V vs Li + /Li) was applied as both active anode material and current collector in zinc-organic batteries with both organic and aqueous , Zn-salt-containing electrolytes . The dendrite formation and the oxidation of zinc can be prevented by lowering the pH value of the aqueous electrolyte …”

The storage of electric energy is of ever growing importance for our modern, technology-based society, and novel battery systems are in the focus of research. The substitution of conventional metals as redox-active material by organic materials offers a promising alternative for the next generation of rechargeable batteries since these organic batteries are excelling in charging speed and cycling stability. This review provides a comprehensive overview of these systems and discusses the numerous classes of organic, polymer-based active materials as well as auxiliary components of the battery, like additives or electrolytes. Moreover, a definition of important cell characteristics and an introduction to selected characterization techniques is provided, completed by the discussion of potential socio-economic impacts.

Poly(2,2,6,6-tetramethylpiperidinyloxy-4-yl acrylamide) was designed and synthesized as an electrode-active polymer for an organic rechargeable device containing an aqueous electrolyte. The device demonstrated a 1.2 V output voltage, exceeded 2000 charging-discharging cycles, and had a high charging rate performance within 1 min.Polyacrylamide is a well-known hydrophilic soft matter widely used in cell culture, drug delivery, and soil amendment. 1-4 Its applications have been vigorously studied in the biological, medical and agricultural fields. On the other hand, the study of the electronic energy related application has been minor and limited to polymer electrolyte fuel cells. 5 We now report a new application of polyacrylamide as an electrode-active material in organic rechargeable devices.Organic-based electrode-active materials have been paid considerable attention because of their potential to overcome the inherent disadvantages of metal-based electrodes, such as limited raw-material resource and tedious waste process. We have focused on the reversible redox reaction of radical species, such as nitroxide, phenoxyl and galvinoxyl radicals, synthesizing a series of aliphatic polymers bearing pendant radical groups (we call them "radical polymer"), and utilizing them as an electrode-active or charge-storage material in a rechargeable device. 6-13 A typical example of a radical polymer is poly(2,2,6,6tetramethylpiperidinyloy-4-yl norbornene). 10 This polymer contains 2,2,6,6-tetramethylpiperidin-1-oxyl-4-yl (TEMPO) groups which are rapidly, reversibly, and stoichiometrically oxidized to the corresponding oxoammonium cation. The poly(TEMPOsubstituted norbornene) was used as the positive electrode (the cathode) ‡ and coupled with a lithium metal negative electrode (an anode) ‡ in a semi-organic rechargeable device containing a LiPF 6 ethylene carbonate/diethyl carbonate (1/1) solution. The device demonstrated a high charging-discharging performance, such as a 3.6 V output voltage, rapid charging within 1 min, and exceeded 1000 charging-discharging cycles. 12 In addition, a test cell composed of the poly(TEMPO-substituted norbornene) cathode, poly(galvinoxylstyrene) anode and (

Tailor-made polymers containing specific chemical functionalities have ushered in a number of emerging fields in polymer science. In most of these next-generation applications the focus of the community has centered upon closed-shell macromolecules. Conversely, macromolecules containing stable radical sites have been less studied despite the promise of this evolving class of polymers. In particular, radical-containing macromolecules have shown great potential in magnetic, energy storage, and biomedical applications. Here, the progress regarding the syntheses of open-shell containing polymers are reviewed in two distinct subclasses. In the first, the syntheses of radical polymers (i.e., materials composed of nonconjugated macromolecular backbones and with open-shell units present on the polymer pendant sites) are described. In the second, polyradical (i.e., macromolecules containing stabi-lized radical sites either within the macromolecular backbone or those containing radical sites that are stabilized through a large degree of conjugation) synthetic schemes are presented. Thus, the state-of-the-art in open-shell macromolecular syntheses will be reported and future means by which to advance the current archetype will be discussed. By detailing the synthetic pathways possible for, and the inherent synthetic limitations of, the creation of these functional polymers, the community will be able to extend the bounds of the radical-containing macromolecular paradigm.
