  1. 1. Realization of Sodium-ion Batteries : From Electrode to Electrolyte Materials

    Författare :Ronnie Mogensen; Reza Younesi; Daniel Brandell; Kang Xu; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Sodium-ion batteries; electrolytes; Prussian white; Chemistry with specialization in Inorganic Chemistry; Kemi med inriktning mot oorganisk kemi;

    Sammanfattning : Batteries are among the most important technologies required to enable the world to move beyond fossil fuels towards a more efficient and environmentally friendly society based on electricity from renewable sources. Unfortunately, the rapidly increasing number and size of batteries that the world needs in order to perform this paradigm shift is putting enormous strain on the supply of traditional raw materials for batteries, such as lithium and cobalt.

    Sammanfattning : In order to move away from fossil fuels, batteries are one of the most important technologies to store energy from renewable sources. The rapid demands of battery applications put pressure on supply chains of raw materials, such as lithium, nickel, copper, aluminium and cobalt. LÄS MER

  5. 5. Some aspects on TCF-bleachability of softwood alkaline pulps

    Författare :Karin Sjöström; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bleachability; chlorine-free bleaching; softwoods; kraft pulps; alkaline sulfite pulps; oxygen; hydrogen peroxide; ozone; hydrogen sulfide ion; hydroxide ion; temperature; sodium ion.; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Sammanfattning : The bleachability of softwood oxygen delignified pulps has been studied, i.e. the ease (requirement of bleaching chemicals) with which the pulps can be brightened to a target brightness in totally chlorine free (TCF) bleaching stages, including hydrogen peroxide, ozone and chelating agent stages.
