  1. 1. Operando X-Ray Imaging of Battery Electrodes

    Author : Antoine Klein; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; lithium-ion batteries; XTM; sodium-ion batteries; lithium-sulfur batteries; SAXS.; X-ray imaging;

    Abstract : Batteries are now part of our daily life as they enable easy usage of portable devices and are now essential for us to travel, communicate, work, read, or listen to music. The diversity of battery applications continuously increases and new demands of for instance capacity, charge time and sustainability have emerged. READ MORE

  2. 2. In-situ Investigations of Lithium-Sulfur Batteries

    Author : Matthew Sadd; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : As the demand for high energy-density storage devices increases, we must look beyond the current state of the art technology, the lithium-ion battery. Lithium-ion battery technologies are approaching their theoretical limit in terms of capacity, and now that the demand for longer-range electric vehicles (EVs) and the implementation of grid storage is increasing, we need to provide technologies that can go beyond what is currently possible.

  3. 3. Heteroatom-doped porous carbon materials derived from poly(ionic liquid)s and their composites for battery and catalytic applications

    Author : Sadaf Saeedi Garakani; Jiayin Yuan; Diego Cazorla-Amorós; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Heteroatom doped carbon; Porous carbon membrane; Poly ionic liquid -derived carbon; Wood-derived carbon; Catalytic activity; Peroxidase-like activity; lithium sulfur battery; materialkemi; Materials Chemistry;

    Abstract : In the past decade, there has been significant interest in heteroatom-doped porous carbons, driven by the distinctive and adjustable physical and chemical properties that they exhibit across scales, from the atomic to the macroscopic level. Particularly, attributes such as conductivity, electron density, high specific surface area, hierarchical pore structure, and oxidation resistance offer a wide range of characteristics for diverse applications.

  4. 4. Operando Analysis of Materials and Processes in Next Generation Batteries

    Author : Matthew Sadd; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : With the rise in popularity of electric vehicles and electromobility solutions, there is a higher than ever demand for high energy density batteries. Accompanying this increased demand there is also an increased pressure for lower costs, longer durability, and the use of more sustainable materials. READ MORE

  5. 5. Operando Characterisation of Lithium–Sulfur Batteries

    Author : Yu-Chuan Chien; Daniel Brandell; Matthew Lacey; Paul Shearing; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; lithium–sulfur batteries; operando characterisation; intermittent current interruption; X-ray diffraction; small-angle scattering; electrochemical impedance spectroscopy; Chemistry with specialization in Inorganic Chemistry; Kemi med inriktning mot oorganisk kemi;

    Abstract : Lithium–sulfur (Li–S) batteries have been under the spotlight of research on electrochemical energy storage systems, primarily owing to their high theoretical specific energy (2552 Wh kg-1). So far, Li–S cells on the market have presented a specific energy of 400 Wh kg-1, which is superior to many commercial alternatives, but far below the theoretical value. READ MORE
