  1. 16. Spectroelectrochemical analysis of the Li-ion battery solid electrolyte interphase using simulated Raman spectra

    University essay from Uppsala universitet/Fasta tillståndets fysik

    Author : Edvin Andersson; [2020]
    Keywords : Lithium Ion Battery; Solid Electrolyte Interphase; Surface Enhanced Raman Spectroscopy; Density Functional Theory; LIB; SEI; SERS; DFT;

    Abstract : Lithium Ion Batteries (LIBs) are important in today's society, powering cars and mobile devices. LIBs consist of a negative anode commonly made of graphite, and a positive cathode commonly made from transition metal oxides. Between these electrodes are separators and organic solvent based electrolyte. READ MORE

  3. 17. Carbon materials from biomass for supercapacitors

    University essay from KTH/Tillämpad fysik
