  1. 1. Investigating self-discharge in a graphite dual-ion cell using in-situ Raman spectroscopy.

    University essay from Uppsala universitet/Strukturkemi

    Author : Ismail Yussuf Hassan; [2023]
    Keywords : graphite; dual-ion battery; parasitic reaction; cathode-electrolyte interface; anion intercalation; concentrated electrolyte; self-discharge; Raman spectroscopy;

    Abstract : Anion intercalation in the graphite positive electrode of a dual-ion battery requires high potential (> 4.3 V vs Li+/Li), which aggravates parasitic reactions involving electrolyte decomposition and Al corrosion, manifesting in poor coulombic efficiency, cycle life, and quick self-discharge.

  3. 2. Electrosynthesis of persulfate and hydrogen gas with boron doped diamond as the anode material

    University essay from KTH/Kemiteknik

    Author : Sandra Shneker; Tsion Abebaw Kebede; Vera Lindbäck; [2022]
    Keywords : Boron-doped diamond; persulfate; flow cell; electrosynthesis; current efficiency;

    Abstract : The efficiency of boron-doped diamond electrodes (BDD) has been investigated by electrolysis of an aqueous solution containing sodium sulfate. A Synthesis StarterKit from Condias was used, which contained the BDD anode with an active surface area of 3.14 cm2, and electrosynthesis was performed in a batch mode reactor. READ MORE

  4. 3. Electrodialytic Remediation of PFAS-Contaminated Soil

    University essay from KTH/Vatten- och miljöteknik

    Author : Georgios Niarchos; [2018]
    Keywords : Per- and polyfluoroalkyl substances; Electrokinetic; Ground; Groundwater; Treatment; Electrochemistry; Environment; Per- och polyfluoralkylsubstanser; Electrokinetisk; Grundvatten; Förorening; Elektrokemi; Miljö;

    Abstract : Per- and polyfluoroalkyl substances (PFASs) are a group of anthropogenic aliphatic compounds, widelyknown for their environmental persistence and toxicity to living beings. While they are ubiquitous in theenvironment, interest has been focused on contaminated soil, which can act as a primary recipient andsource of groundwater contamination. READ MORE

  5. 4. Separation of water out of highly concentrated electrolyte solutions using multistage vacuum membrane distillation

    University essay from KTH/Kraft- och värmeteknologi

    Author : Bin Jiang; [2013]
    Keywords : membrane distillation; concentration; LiCl; CH3COOK;

    Abstract : Absorption dehumidification requires regeneration system to regenerate diluted desiccant solutions, which are still highly concentrated. A novel multi-stage vacuum membrane distillation system was applied for separating water out of the highly concentrated solution. READ MORE
