“…Carbon species, metal compounds and conducting polymers (CPs) are the main types used as electrode materials. Carbon species that used as electrode materials typically include graphene [4][5][6][7], carbon nanotubes [1], porous nano-carbons [4,8,9] and activated carbon [10] due to their fast charging capabilities and high conductivity [1]. However, their low loading density will result in low energy density, which largely limits their applications for energy storage and conversion.…”

Conducting polyaniline (PANI) with high conductivity, ease of synthesis, high flexibility, low cost, environmental friendliness and unique redox properties has been extensively applied in electrochemical energy storage and conversion technologies including supercapacitors, rechargeable batteries and fuel cells. Pure PANI exhibits inferior stability as supercapacitive electrode, and can not meet the ever-increasing demand for more stable molecular structure, higher power/energy density and more N-active sites. The combination of PANI and other active materials like carbon materials, metal compounds and other conducting polymers (CPs) can make up for these disadvantages as supercapacitive electrode. As for rechargeable batteries and fuel cells, recent research related to PANI mainly focus on PANI modified composite electrodes and supported composite electrocatalysts respectively. In various PANI based composite structures, PANI usually acts as a conductive layer and network, and the resultant PANI based composites with various unique structures have demonstrated superior electrochemical performance in supercapacitors, rechargeable batteries and fuel cells due to the synergistic effect. Additionally, PANI derived N-doped carbon materials also have been widely used as metal-free electrocatalysts for fuel cells, which is also involved in this review. In the end, we give a brief outline of future advances and research directions on PANI.

“…Despite their high delivered capacitance, pseudocapacitive materials suffer from their poor conductivity that limits the rate performance and the life-span of the final devices [26]. To improve the electrode conductivity, generally the electroactive pseudocapacitive materials are coupled with high conductivity materials, such as carbon materials or metallic foams, requiring the employment of insulating binder to ensure contact between the high conductivity materials and the active phase [27][28][29][30][31][32]. A different approach to ensure high conductivity of the electrodes involves the hydrothermal synthesis route.…”

“…Up to now, various materials, such as carbon-based materials [9][10][11][12][13] [14][15][16][17][18][19][20][21][22][23][24][25], and conducting polymers [26][27][28][29], have been widely used as supercapacitor electrodes. Since carbon-based materials adopt an electric double-layer mech-anism, the capacitance performance is relatively lower than that of Faradaic pseudocapacitance, which has become the main bottleneck in the practical application of such materials.…”

A hierarchical structure of TiO2 nanorod/MnO2 ultrathin nanosheet core/shell nanocomposite arrays on a conductive substrate has been prepared by two facile steps of hydrothermal reaction and annealing progress, which serving as electrodes present great potential application for high-performance supercapacitors. By adjusting the concentration of precursor aqueous solution, it can be found that the thickness of the MnO2 shell in the as-designed hierarchical electrode material can be facilely controlled. By comparison, the obtained TiO2 nanorod/MnO2 ultrathin nanosheet as an electrode material can achieve the best electrochemical performance in terms of the area-specific capacitance up to 34.79 mF/cm2 from the cyclic voltammetry (CV) test at the scan rate of 5 mV/s. Furthermore, the composited electrode has also demonstrated good stability, with the capacitance retention rate of about 91% through the cycle experiment test after 1000 cycles.
