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

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

    Sammanfattning : 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. LÄS MER

  3. 2. Recycling of nickel metal hydride (NiMH) batteries; Characterization and recovery of nickel, AB5 alloy and cobalt

    Författare :Filip Holmberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; recycling; nickel; AB5 alloy; cobalt; NiMH battery; hydrogen storage alloy; leaching;

    Sammanfattning : Nickel metal hydride (NiMH) batteries are used today for applications that can assist in the adaptation toward carbon-neutral energy sources (i.e. hybrid vehicles and smart grids). Recovery of metals such as nickel, cobalt and rare earth elements (REEs) from discarded NiMH batteries is important for economic and/or technological reasons. LÄS MER

  4. 3. Antimony recovery from complex copper concentrates through hydro- and electrometallurgical processes

    Författare :Samuel Ayowole Awe; Olof Forsén; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

    Sammanfattning : Today, one of the major difficulties confronted during copper metallurgy is the elimination of antimony and arsenic impurities from the process. This is because the pure copper ore reserves are becoming exhausted and the resources of unexploited ores often contain relatively high amounts of antimony and arsenic. LÄS MER

    Sammanfattning : The purpose for this work has been to develop new robust fuel electrodes for solid oxide fuel cells (SOFC). The aim was to find suitable ceramic materials or composites with promising properties for the use as SOFC anodes. LÄS MER

  7. 5. Ceria-based Nanostructured Materials for Low-Temperature Solid Oxide Fuel Cells

    Författare :Ying Ma; Mamoun Muhammed; Bin Zhu; Randa Abdel-Karim; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : As one of the most efficient and environmentally benign energy conversion devices, solid oxide fuel cells (SOFC) have attracted much attention in recent years. Conventional SOFC with yttria-stabilized zirconia as electrolyte require high operation temperature (800-1000 °C), which causes significant problems like material degradation, as well as other technological complications and economic barrier for wider applications.
