“…For instance, polyaniline (PANI) is estimated to demonstrate an ultra‐high theoretical capacitance of 2000 Fg −1 [155] . Again, PEDOT, a polythiophene derivative, displays high optical transparency in conducting state that expands the domain of usage in various multifunctional energy storage devices [156] . Thus, conducting polymers have been blended in appropriate proportions with other components to obtain novel nanocomposites to accomplish superior supercapacitive performances in the recent past [157] .…”

Manganese dioxide (MnO2) has proved itself as a popular pseudocapacitive material with low fabrication cost, high availability, low toxicity, and improved handling safety compared to many other inorganics or carbon‐based systems existing in the market. However, the specific capacitance reported to date has been far inferior to that of the theoretically predicted value (ca. 1370 Fg−1), which is mainly attributed to the issues associated with poor conductivity, nanostructure agglomeration, low porosity, rapid electrolyte‐mediated dissolution, and so forth, which have considerably limited its commercial effectiveness. Thus, to bring about improvement in the electrochemical performance of MnO2‐based supercapacitors, novel designs of MnO2 nanomaterials through composite formations with other substances, such as nanocarbons, conducting polymers or inorganic materials, namely metal oxides and sulfides, have been comprehensively explored. Extensive studies on these MnO2 binary nanocomposites revealed significant improvement in the electrochemical features compared to pristine phases; nevertheless, the achieved state is still far below practicability. Hence, scientists have opted for MnO2‐based ternary nanocomposites achieved by blending appropriate proportions the three components (MnO2 nanostructures being one of the constant components) that would promote synergism to attain suitable dimensions, crystallinity, crystal structure, conductivity, mass loading, and electrolyte selectivity so as to confer superior capacitance, charge transfer kinetics, better utilization of electroactive materials, energy and power densities, as well as improved mechanical stability and environmental adaptability. Herein, recent developments and advancements in the research of various MnO2‐based ternary nanocomposites employed for supercapacitor applications have been discussed and are compared with binary analogs with special emphasis on correlating their composition, morphology, and the electrochemical properties that are noticeably modified upon introduction of the third component. The associated challenges encountered in their progress toward commercialization and the probable ideas of persuading better strategic designs of these ternary systems for high‐performance supercapacitor applications have also been delineated.

“…A PEDOT:PSS binder disintegrates in a water stream and, hence, EDLCs with coating electrodes with PEDOT:PSS binder can be recycled according to proposed protocols [24] based on liquid processing [25,26] and separation methods [27]. PEDOT:PSS pseudocapacitors have typically aqueous electrolytes, such as 1 M H 2 SO 4 [28] or H 3 PO 4 /PVA gel electrolyte [29,30]. It has been reported [31] that their pseudocapacitance is due to the following reversible redox process between PEDOT:PSS and the H + ion of an aqueous acid electrolyte:…”

Although typical electrochemical double-layer capacitors (EDLCs) operate with aqueous or lithium-free organic electrolytes optimized for activated carbon electrodes, there is interest in EDLCs with lithium-ion electrolyte for applications of lithium ion capacitors and hybridized battery-supercapacitor devices. We present an experimental study of symmetric EDLCs with electrolyte 1 M LiPF6 in EC:EMC 50:50 v/v and electrode coatings with 5 wt% SBR or PEDOT:PSS binder at 5 or 10 wt% concentration, where for the PEDOT:PSS containing electrodes pseudocapacitance effects were investigated in the lithium-ion electrolyte. Two different electrode coating fabrication methods were explored, doctor blade coating and spraying. It was found that EDLCs with electrodes with either binder had a stability window of 0–2 V in the lithium-ion electrolyte. EDLCs with electrodes with 10 wt% PEDOT:PSS binder yielded cyclic voltammograms with pseudocapacitance features indicating surface redox pseudocapacitance in the doctor blade coated electrodes, and intercalation and redox phenomena for the sprayed electrodes. The highest energy density in discharge was exhibited by the EDLC with doctor blade-coated electrodes and 10 wt% PEDOT:PSS binder, which combined good capacitive features with surface redox pseudocapacitance. In general, EDLCs with sprayed electrodes reached higher power density than doctor blade coated electrodes. Graphic abstract

“…Recently, a class of electrochemical supercapacitors (SC) based on conducting polymers (CP) has gained much attention in the research community owing to the abundance of the constituent materials, outstanding mixed ion-electron conductivity and high volumetric capacitance values 1,2 . Due to its remarkable cycling stability and high mixed conductivity, the organic conjugated polymer poly(3,4-ethylenedioxythiophene): poly(styrene sulfonate) (PEDOT:PSS) has been investigated in many SC settings; as freestanding 3,4 films, mixed with different forms of carbon/cellulose 5,6 to promote high surface area, and in combination with redox molecules/biopolymers [7][8][9][10][11] for higher energy density. However, achieving high energy density with good cycling stability in PEDOT:PSS-based SCs is limited as most of the previous works utilizes aqueous electrolytes.…”
