“…A variety of high-performance anodes based on organic materials has been reported in previous works (Tables S1, S2 and Figure S9 in the Supplementary Information) [41][42][43][44][45][46][47][48][49][50][51][52][53][54][55][56] . Although a high specific capacity was reported for organic anodes based on low-molecular-weight compounds (Table S1 in the Supplementary Information) 41-51 , their cycle stability was not studied and determined.…”

“…Although a high specific capacity was reported for organic anodes based on low-molecular-weight compounds (Table S1 in the Supplementary Information) 41-51 , their cycle stability was not studied and determined. The polymer-based organic anode possesses cycle stability (Table S2 in the Supplementary Information) [52][53][54][55][56] . The present PTp-COOH nanoparticles showed one of the best performances, including the specific capacity and cycle stability, of the polymer-based organic anodes ( Figure S9 in the Supplementary Information).…”

“…Although a high specific capacity was found with low-molecular-weight compounds (Table S1 in the Supplementary Information) [41][42][43][44][45][46][47][48][49][50][51] , their solubility and low conductivity caused problems with the cycle stability. A high specific capacity and cycle stability were achieved with polymer-based anodes, such as polydopamine and heterocyclic ladder polymers (Table S2 in the Supplementary Information) [52][53][54][55][56] . However, the design strategies for the molecules and hierarchical morphologies were not fully studied to achieve further improved properties in polymer-based anodes.…”

“…Nanoparticles of PPy and PTp with carboxy groups (PPy-COOH and PTp-COOH) have specific capacities of 730 and 963 mAh g -1 , respectively, at 20 mA g -1 with stable cycle performances. In recent years, redox-active organic materials based on π-conjugated molecules have attracted much interest as high-performance anodes for lithium-ion batteries [39][40][41][42][43][44][45][46][47][48][49][50][51][52][53][54][55][56] . The π-conjugated molecules with carboxy substituents, such as phthalic acid and muconic acid, have a reversible redox reaction based on lithium alkoxylation at approximately 1.0 V vs. Li/Li +41,42 .…”

Conducive polymers have a wide range of applications originating from their π-conjugated systems. The redox reactions of conductive polymers with doping and dedoping of anions have been applied to cathodes for charge storage. In contrast, the redox reactions with cations have not been fully studied in anodes for charge storage. Here, we found that the nanostructures of conductive polymers, such as polypyrrole (PPy) . The introduction of a carboxy group to the pyrrole and thiophene rings enhanced the specific capacities up to 730 and 963 mAh g -1 , respectively. The enhanced electrochemical properties were not observed in the bulk-size conductive polymers. The results suggest that conductive-polymer nanostructures have potential for developing metal-free, high-performance charge storage devices.

Core/shell structures of carbon-based materials/ metal oxide have been considered as potential candidates for electrochemical devices due to their improved pseudocapacitance/electrical double layer capacitance and high conductivity/ superior surface area. The development of multiple coreshell structures of MWCNT@MnO 2 @PPy was analyzed as a standard procedure for mass production of supercapacitor electrodes. The relative concentration of carbon nanotubes in the composite was varied to optimize the double layer capacitance contribution in overall response of device. Resulting structures presented capacitance in order of 272.7 Fg -1 and reasonable cycling performance.

The increasing demand on energy storage for different applications requires the development of more sustainable secondary batteries. In this context, this article describes the benefits and the drawbacks of the organic active materials for the electrochemical storage. After discussing the opportunity offered by full‐organic batteries, the advantages and challenges of the organic materials are discussed. Then, the main electroactive functions (conjugated polymers, stable radicals, sulfur‐based materials, carbonyl‐based materials, and the miscellaneous approaches) and their electrochemical mechanisms are described in detail, giving examples of the most relevant and promising materials reported in the literature. Further, the three main strategies (“polymer” approach, polyanionic salt formation, and solid‐state approach) employed to overcome the solubility issues of the organics in the common electrolytes are developed, with practical relevant examples from the literature. Then, the second main drawback of the organic active materials, i.e. the very low electronic conductivity, is addressed by two means: the use of specific carbon additives and the functionalization of conducting polymer by electrochemically active moieties. Finally, an overview of the seminal works and/or the most relevant full‐organic cell configurations is critically described.
