摘要: An extremely high-performance polyaniline electrode was prepared by potentiostatic deposition of aniline on hierarchically porous carbon monolith (HPCM), which was carbonized from mesophase pitch. A capacitance value of 2200 F g−1 of polyaniline was obtained at a power density of 0.47 kW kg−1 and an energy density of 300 Wh kg−1. This active material deposited on HPCM also has an advantageous high stability. These superior advantages can be attributed to the backbone role of HPCM. This method also has the advantages of not introducing any binder, thus contributing to the increase of ionic conductivity and power density. High specific capacitance, high power and energy density, high stability, and low cost of active material make it very promising for supercapacitors.

摘要: This disclosure relates to a porous electrically conductive carbon material having interconnected pores in first and second size ranges from 10 μm to 100 nm and from less than 100 nm to 3 nm and a graphene structure and to diverse uses of the material such as an electrode in a lithium-ion battery and a catalyst support, e.g. for the oxidation of methanol in a fuel cell. The carbon material has been heat treated to effect conversion to non-graphitic carbon with the required degree of order at a temperature in the range from 600° C. to 1000° C. A lithium-ion battery and an electrode for a lithium-ion battery are also claimed.
