  2. 1. Critical potential and oxygen evolution of the chlorate anode

    Author : Linda Nylén; Göran Lindbergh; Yohannes Kiros; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; chlorate; chloride oxidation; oxygen evolution; critical anode potential; chromate; DSA; mass transport; RDE; Chemical engineering; Kemiteknik;

    Abstract : In the chlorate process, natural convection arises thanks to the hydrogen evolving cathode. This increases the mass transport of the different species in the chlorate electrolyte. There is a strong connection between mass transport and the kinetics of the electrode reactions. READ MORE

  4. 2. The anode in a PEFC reformate system

    Author : Sofia Enbäck; KTH; []
    Keywords : polymer electrolyte fuel cell system; anode; CO oxidation;

    Abstract : Polymer electrolyte fuel cells (PEFC) constitute one ofseveral types of fuel cells that can be used to converthydrogen to electricity and heat. PEFC co-generation systemsbased on fossil fuels are on the edge of commercialisation.Biogas may be a future fuel in these kinds of systems. READ MORE

  5. 3. Tin-based Glasses: Structure and Electrochemical Properties

    Author : Cecilia Gejke; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Li-ion battery; anode; borate glasses; phosphate glasses; tin; reverse Monte Carlo simulation; Raman spectroscopy; infrared spectroscopy; neutron diffraction;

    Abstract : This thesis presents an investigation of microscopic structure and electrochemical properties, and their relationship, for various tin-based borate, phosphate and borophosphate glasses. Tin-based glasses have attracted a lot of scientific interest as anode materials in Li-ion batteries. READ MORE

  6. 4. Lithium titanate as anode material in lithium-ion batteries : -A surface study

    Author : Tim Nordh; Kristina Edström; Daniel Brandell; Carl Tengstedt; Carla Puglia; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; titanate battery anode SEI; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Abstract : The ever increasing awareness of the environment and sustainability drives research to find new solutions in every part of society. In the transport sector, this has led to a goal of replacing the internal combustion engine (ICE) with an electrical engine that can be powered by renewable electricity. READ MORE

  7. 5. Influence of the electrolyte on the electrode reactions in the chlorate process

    Author : Linda Nylén; Göran Lindbergh; Ann Cornell; Mårten Behm; Geoeff H Kelsall; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chlorate; chloride oxidation; critical anode potential; chromate; DSA; hydrogen evolution; iron; mass transport; oxygen evolution; REM; RDE; steel; Electrochemistry; Elektrokemi;

    Abstract : The chlorate process is very energy intensive and a major part of the production costs are for electrical energy. Since the electricity prices are constantly increasing and may also vary periodically, the chlorate plants may be forced to adjust their production rate to the price at each moment in order to minimise their costs.
