“…However, monomers 3 and 4 are expected to undergo redox processes before the oxidation of NMP. We previously studied PEDOT-TAPD (equivalent to Py-2C-TMPD, in this work) 26 and were unable to electropolymerize this monomer with such a short alkyl linker. The separation of the RAP and the Py by the alkyl linker is intended to decrease charge localization (electrostatic repulsion) and improve stability as the monomers become triply and quadruply charged for monomers 3 and 4, respectively, during the electropolymerization process.…”

“…These values are three times higher than the energy densities typically observed for organic radical materials and are among the highest for organic materials. 15 A series of monomers was synthesized based on literature precedent 26 (Scheme 1). The alkyl linkers were installed via a substitution reaction with dibromoalkyls (Scheme 1a), and the redoxactive precursors were attached onto the pyrrole alkyls via substitution (Scheme 1b).…”

“…Nonetheless, previous studies found that while decreasing molecular weight elevates capacities, complications during electropolymerization arose, and the effective (electro)polymerization could be impeded for some of the monomer materials studied. 26 ) unless CC License in place (see abstract Herein, we report on the rational design, synthesis and electrochemical characterization of a library of electropolymerizable monomers, constructed from a pyrrole (Py) unit and a variety of RAPs that can exchange multiple electrons per monomer unit at high voltages. The results demonstrate and validate the concept that our design is a viable method to obtain high performing electrode materials and will guide the future design of new organic electrodes for electrical energy storage applications.…”

“…The former is included to provide electronic conductivity (over the appropriate potential range) and the latter to maximize working voltages and capacities and, thus, energy density. 26,27 The CPs provide enhanced electronic conductivity for the polymer, and also serve to prevent dissolution of the RAPs during cycling by anchoring/immobilizing them onto the current collectors. In a previous study, poly (3,4-ethylenedioxythiophene) tetraalkylphenylenediamine (PEDOT-TAPD) exhibited high theoretical capacities, near 220 mAh/g (ca.…”

In an effort to dramatically increase the capacity and electronic conductivity of organic-based redox active materials for electrochemical/electrical energy storage applications, polypyrrole (PPy) has been used as an anchoring backbone to form a family of dimethoxybenzene-(DMB-), bis(methylthio)benzene- (BMTB-), N, N, N', N'-tetramethylphenylenediamine-(TMPD-), and N, N, N', N'-tetramethylbenzidine-(TMB-) functionalized redox-active polymers. PPy was deliberately modified to provide an electronically conducting backbone with redox active pendants (RAPs) to enable immobilization (via electropolymerization) of the polymers onto current collectors. The RAPs dramatically increase the capacities of the materials by the reversible exchange of multiple electrons per formula unit. The electropolymerization of the pyrrole-anchored RAP monomers was achieved via cyclic voltammetry. The stability of the electropolymerized films was highly dependent upon the redox potential of the RAPs. The effects of charge density, during the electropolymerization process, were studied by varying the structure of the monomers. By the systematic characterization of the electrochemical properties of the electropolymerized films, the electrochemical behavior of these polymers provides validation of our targeted design to maximize the energy density of organic electrode materials for electrical energy storage applications. With limited fossil fuel reserves and accelerating climate change, the world is shifting towards using renewable and sustainable energy sources. This shift requires dramatic improvements in the fields of carbon-neutral, renewable energy conversion, and, most importantly, the subsequent electrical energy storage technologies. As a result, electrical energy storage (EES) technologies such as batteries and electrochemical capacitors represent one of the fastest developing fields for use in areas such as transportation, electronics, and grid energy storage.1,2 Among these technologies, lithium-ion batteries (LIBs) exhibit among the best combined properties in terms of energy and power density. [3][4][5] In these devices, lithium-intercalated materials (LIM), especially LiC 6 , are used as the anode, as they represent safer alternatives to lithium metal anodes which are prone to lithium dendrite growth that severely compromises safety.6-11 Numerous lithium transition-metal oxides (LiM x O y ) have been developed as cathode materials and have dramatically increased the energy density of the devices. 4,12 However, the use of LIM as anodes and LiM x O y cathodes is limited, at least in part, by the availability of lithium and transition metals.2,13 Moreover, the limited ability of LiM x O y cathodes to undergo multiple electron transfers per formula unit and their moderate working voltages limit the energy density of these materials. 12In addition, the use of intercalation materials often places limits on the operational C-rates, effectively limiting power density. Organic molecules represent attractive alternatives as they are co...

In this work, we developed a synthetic method for preparing one-dimensional MnO2 nanowires through a hydrothermal method using a mixture of KMnO4 and MnSO4 precursors. As-prepared MnO2 nanowires had a high surface area and porous structure, which are beneficial to the fast electron and ion transfer during electrochemical reaction. The microstructure and chemical structure of MnO2 nanowires were characterized by scanning electron microscopy, transmission electron microscopy, X-ray photoelectron spectroscopy, X-ray diffraction, and Brunauer-Emmett-Teller measurements. The electrochemical properties of MnO2 nanowire electrodes were also investigated using cyclic voltammetry and galvanostatic charge-discharge with a three-electrode system. MnO2 nanowire electrodes showed a high specific capacitance of 129 F/g, a high rate capability of 61% retention, and an excellent cycle life of 100% during 1000 cycles.
