“…The values of the HOMO and LUMO energy levels determine properties such as oxidative stability, optical absorption wavelengths, and whether a polymer is more likely to be n-type or p-type. 26,42 Polymers can be classified as being either n-type or p-type based on whether they are easily reduced or oxidized, respectively. Electron rich structures that have higher HOMO levels make good p-type materials due to their ability to stabilize a positive charge, while electron poor structures are able to stabilize negative charges in low-lying LUMO levels, making them good n-type materials.…”

“…18,22,29 In light of this, conjugated polymers are ideal materials for hybrid composites in that they work synergistically with inorganic compounds that have high capacity but lack the conductivity and cyclability necessary for commercial application. [23][24][25][26] The combination of synthetic tuning, processing options, and mechanical flexibility results in plastic power sources that can be designed to suit the device rather than vice versa.…”

Poly(dithieno[3,2-b:2,3-d]pyrrole)s, or poly(DTP)s, are potentially promising electrode materials for electrochemical energy storage (EES) because of their ability to reversibly store charge and achieve relatively high doping levels. Here, we explore charge storage in two different side-chain-substituted poly(DTP)s. Substitution at the nitrogen with alkyl and alkyl ether chains is used to demonstrate the ability to tune electrochemical response through favorable interactions with the electrolyte. PolyDTP electrodes are electropolymerized and analyzed using various electrochemical techniques, spectroscopic measurements including UV–vis and Raman, and electron microscopy. Specific capacities for the poly(DTP)s range between approximately 35 and 70 mAh/g for discharge rates of 1–75 C, corresponding to considerably high doping levels of 0.5–0.9 electrons per repeat unit. After 1000 cycles, the alkyl-substituted polymer retains 75% of its initial capacity while the alkyl ether-substituted polymer only retains 50%. The specific capacitance was as high as 121 F/g. These results suggest that poly(DTP)s could be utilized on their own or in composite electrodes for energy storage.

Polymers have a particularly important place in electrochemical energy storage (EES), not just as the electrolyte, as has been a large focus for solidstate batteries, but also as the electrode. This Viewpoint will introduce how electrochemically active polymers (EAPs) are utilized in electrochemical energy storage with an emphasis on battery cathodes. Recent advances in high capacity EAPs and selected challenges (high voltage stability and ion transport) are presented. Should these needs be met, the resulting electrode would bear a high capacity, energy, power, and cycle life. The low cost, potential application in flexible EES, and synthetic versatility of EAPs offer many unique aspects relative to conventional metal oxides. In composites with metal oxides, EAPs can be used as a means to boost ionic and electronic conductivity. Promising examples regarding high capacity polymeric sulfur electrodes, electrochemically stable polyaniline/ polyacid complexes, porous polyaniline/V 2 O 5 electrodes, and hydrogel-based electrodes are highlighted.
