  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. Sustainable Recycling of Electrolytes for Vanadium Redox Flow Batteries : Method development and Review (Bachelor Thesis)

    University essay from Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Author : Reza Doulati; [2023]
    Keywords : vanadium redox flow batteries VRFB; eco-friendly recycling; precipitation of vanadium; vanadium oxides; Energy storage system; ESS; circular economy; sustainable recycling method;

    Abstract : Vanadium Redox Flow Batteries VRFBs are promising energy storage systems with highly recyclable electrolytes. The recycling of these systems usually involves ammonium-based salt precipitation steps, which produce toxicgases and contaminated water as waste. READ MORE

  4. 3. Application of electrodes with redox mechanisms for the desalination of water

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Pablo Moreno Cerezo; [2023]
    Keywords : Activated Carbon Cloth ACC ; Capacitive Deionization CDI ; Cyclic Voltammetry CV ; Electrochemistry; Polyaniline PANI ; Prussian Blue PB and Redox Reactions; Aktivt koltyg ACC ; Kapacitiv avjonisering CDI ; Cyklisk voltammetri CV ; Elektrokemi; Polyanilin PANI ; Preussisk blå PB och Redoxreaktioner;

    Abstract : Capacitive deionization is a promising technology for purification and desalination of brackish water with great advantages over current technologies due to its low operating cost and high-water recovery ratio. Most of the system studied relies on the adsorption/desorption capacity of activated carbon electrodes due to its high surface area. READ MORE

  5. 4. Electrochemical Characterisation of LiFePO4-Coated Carbon Fibres: A Comparative Electrochemical Analysis of Three Coating Methods

    University essay from KTH/Tillämpad elektrokemi

    Author : Julia Szecsödy; [2023]
    Keywords : Structural battery composite; Carbon fibres; Lithium-ion battery; Electrophoretic deposition; Spray coating; Powder impregnation; Strukturella batteri kompositer; Kolfiber; Litiumjon batteri; Elektroforetisk beläggning; Sprutbeläggning; Pulverimpregnering;

    Abstract : Kolfiber CF kan användas som positiv elektrod i strukturella batterier om de beläggs med ett aktivt material, såsom litiumjärnfosfat LFP. Fördelen med att använda kolfibrer som elektroder är att de samtidigt kan bära mekanisk belastning och lagra elektrisk energi. Det finns flera tekniker för att belägga kolfibrerna. READ MORE

  6. 5. On the stability of current collectors in high-voltage lithium-ion batteries containing LiFSI electrolytes

    University essay from Uppsala universitet/Oorganisk kemi

    Author : Kevin Carlö; [2023]
    Keywords : LiFSI; high-voltage; anodic dissolution; corrosion; aluminum; current collector; electrolyte; battery;

    Abstract : The increasing energy demand requires a transition from fossil fuels to renewable resources. Lithium-ion batteries (LIBs) offer a promising solution as efficient energy storage devices. However, the aluminum current collector (CC) in LIBs is susceptible to anodic dissolution above 3 V vs. READ MORE
