Patent number: 8481642Abstract: The present invention relates to a process for the preparation of hydrothermal hybrid material, in particular coal-like hybrid material from biomass. The process involves the heating of a reaction mixture comprising water, biomass and a copolymerizable compound, wherein the copolymerizable compound is added when preparing the reaction mixture, in a variant of the process, the biomass is converted to activated biomass in a first step, and the copolymerization of the activated biomass and a copolymerizable compound to give the hydrothermal, preferably coal-like, hybrid material is started by adding a polymerization initiator. The invention also relates to the hydrothermal hybrid materials obtainable by the processes as such, e.g. to aqueous dispersions thereof. By incorporating copolymerizable compounds, e.g. petrochemical compounds in the structure of the hydrothermal hybrid materials, the physical properties of the materials and the preparation process thereof can be controlled.Type: GrantFiled: June 22, 2009Date of Patent: July 9, 2013Assignee: CSL Carbon Solutions Ltd.Inventors: Markus Antonietti, Maria Magdalena Titirici, Rezan Demir Cakan

Patent number: 8164881Abstract: 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.Type: GrantFiled: May 25, 2007Date of Patent: April 24, 2012Assignee: Max-Planck-Gesellschaft zur Foerderung der Wissenschaften e.V.Inventors: Yong-Sheng Hu, Yu-Guo Guo, Lizhen Fan, Joachim Maier, Philipp Adelhelm, Bernd Smarsly, Markus Antonietti
