“…The films were charged up to 3.8 V and the calculated coulombic efficiency was 98.9 %, similar to that observed by Osaka et al 9 who studied PAni galvanostatically synthesized in the presence of trifluoracetic acid (TFA). The discharging capacity obtained in the present work (107 mA h g -1 ) can be considered high and comparable to the values observed in the literature 11,27 . Echigo et al 11 studied chemically synthesized PAni and they observed a discharging capacity of 118.6 mA h g -1 .…”

“…Echigo et al 11 studied chemically synthesized PAni and they observed a discharging capacity of 118.6 mA h g -1 . Hwang et al 27 studied the charge/discharge characteristics of sulfonated chemically synthesized PAni determining a discharging capacity around 80 mA h g -1 and a coulombic efficiency equal to 90 %. These observations indicate that PAni films electrochemically synthesized in PC solution containing TCA a b c…”

No presente trabalho a caracterização de polianilina eletrosintetizada em meio de carbonato de propileno na presença dos ácidos di-e tricloroacéticos foi realizada usando diferentes técnicas. A resposta eletroquímica por voltametria cíclica mostrou os processos redox devido à formação de polaron e bipolaron e à degradação do polímero. A caracterização usando as espectroscopias no infravermelho e ultravioleta-visível indica que os polímeros estão na forma de sal emeraldina com ânions perclorato incorporados. Os filmes produzidos com ambos os ácidos em carbonato de propileno apresentam morfologia compacta como observado por microscopia eletrônica de varredura. Através de testes de filmes de polianilina produzidos em condições selecionadas em um ambiente correspondente a uma bateria de lítio foi observado que estes apresentam uma eficiência coulômbica elevada promissora para aplicações em baterias.In the present work the characterization of polyaniline electrosynthesized in propylene carbonate medium in the presence of di-and trichloroacetic acids was performed using different techniques. The electrochemical response by cyclic voltammetry showed redox processes due to the formation of polaron and bipolaron and polymer degradation. The characterization by infrared and UVvisible spectroscopies indicated that the polymers are in the emeraldine salt form with perchlorate anions incorporated. The films produced with both acids in propylene carbonate media presented a compact morphology as observed by scanning electron microscopy. By testing the polyaniline film produced in selected conditions in a lithium battery environment it was found that it presents a high coulombic efficiency, promising for battery applications.

“…230 A simple mixture of a conductive binder (SPAn) and ramsdellite MnO 2 was used as a cathodic material for a lithium polymer battery. 231 A concomitant ion exchange and polymerization method was used in MoO 3 /PANI, which provided a moderate increase in cell capacity and improved the reversibility of the Li insertion reaction. 232 An organic-inorganic hybrid material was formed from PANI/hexacyanoferrate (HCF) anion; anchoring of the electroactive anion within the polymer caused its application as a functional material that harnessed the activity of the molecular species.…”

Manganese dioxide (MnO2) has been widely used in the field of energy storage due to its high specific capacitance, low cost, natural abundance, and being environmentally friendly. However, suffering from poor electrical conductivity and high dissolvability, the performance of MnO2 can no longer meet the needs of rapidly growing technological development, especially for the application as electrode material in metal‐ion batteries and supercapacitors. In this review, recent studies on the development of binary or multiple MnO2‐based composites with conductive components for energy storage are summarized. Firstly, general preparing methods for MnO2‐based composites are introduced. Subsequently, the binary and multiple MnO2‐based composites with carbon, conducting polymer, and other conductive materials are discussed respectively. The improvement in their performance is summarized as well. Finally, perspectives on the practical applications of MnO2‐based composites are presented.
