Abstract:A novel π-conjugated monomer tert-butyl 3,8-di([2,2′-bithiophen]-5-yl)-6-oxophenanthridine-5(6H)carboxylate (PNBTH-Boc) with a labile side chain was synthesized. The monomer was electropolymerized to form redoxactive polymer (Poly-PNBTH-Boc) on the current collector. The labile side chains on the polymer were then removed by thermal annealing, resulting in the porous electroactive film (Poly-PNBTH). The annealed polymer exhibited a stable oxidation process and high specific areal capacitance. Asymmetric superc… Show more

“…In many advanced applications, the low-energy density of the SCPs limits its practical applicability as an energy storage device [110][111][112]. In fact, the energy density (E = 1/2 CV 2 ) of the SCPs is linearly dependent on the specific capacitance as well as the square of the operating potential window used for study [43,47,77] To date, researchers have adopted many advanced strategies to increase the specific capacitance of the SCPs, which includes strategies to extend the operating potential window of SCPs and to fabricate the electrode using various high surface area active materials, such as carbon, carbon SWCNTs, MWCNTs, graphene, carbon aerogel, metal oxides hierarchical nano-structured, hierarchical meso-and micro-porous microstructures, organic electroactive molecules as electrode for SCPs [14,88,109,[112][113][114][115]. To increase the operating voltage of SCPs, the new material as electrode in SCPs which can operate at high voltage and deliver more power is a prime requirement.…”

Owing to their extraordinary properties of π-conjugated polymers (π-CPs), such as light weight, structural versatility, ease of synthesis and environmentally friendly nature, they have attracted considerable attention as electrode material for metal-ion batteries (MIBs) and supercapacitors (SCPs). Recently, researchers have focused on developing nanostructured π-CPs and their composites with metal oxides and carbon-based materials to enhance the energy density and capacitive performance of MIBs and SCPs. Also, the researchers recently demonstrated various novel strategies to combine high electrical conductivity and high redox activity of different π-CPs. To reflect this fact, the present review investigates the current advancements in the synthesis of nanostructured π-CPs and their composites. Further, this review explores the recent development in different methods for the fabrication and design of π-CPs electrodes for MIBs and SCPs. In review, finally, the future prospects and challenges of π-CPs as an electrode materials for strategies for MIBs and SCPs are also presented.

In this work, three‐dimensional (3D) nanostructures of polyaniline nano‐sheets, nano‐particles, nano‐nets and nano‐flowers were synthesized with valine, sulfuric acid, sodium acetate and L‐phenylalanine as doping acids, respectively. Conductive polyaniline with 3D nanostructure was proven as an excellent energy storage material because of its superior electrical properties and unique structure. The porous structure not only greatly improved the charge transfer efficiency and reduced the resistance, but also improved the cycle stability and energy storage of the electrode material. Polyaniline nano‐flowers doped with L‐phenylalanine (PANI‐NF) showed a maximum specific capacitance of 580 F g−1(I=0.5 A g−1), a maximum energy density of 53.9 Wh kg−1, and excellent cycle stability at high current density.
