  1. 6. Protein-based hydrogel electrolytes for stretchable Zn-ion batteries

    University essay from Linköpings universitet/Laboratoriet för organisk elektronik; Linköpings universitet/Tekniska fakulteten

    Author : Lovisa Byström; [2023]
    Keywords : Hydrogel; gelatin; kappa-carrangeenan; Zn-ion battery; Kemisk biologi; Kemisk biologi;

    Abstract : Stretchable aqueous-based Zn-ion batteries have shown promise as a sustainable and safe energy storage system for wearable electronics used in healthcare, sports, soft robotics, and prosthetics. A battery consists of the active electrode, electrolyte, current collector, and encapsulation. READ MORE

  3. 7. 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

  4. 8. Operando detection of Li-plating by online gas analysis and acoustic emission monitoring

    University essay from Uppsala universitet/Strukturkemi

    Author : Inti Espinoza Ramos; [2023]
    Keywords : Li-ion batteries; graphite; solid electrolyte interphase; lithium plating; online gas analysis; operando acoustic emission monitoring;

    Abstract : Lithium ion batteries (LIBs) are widely used for storing and converting chemical energy into electrical energy. During battery operation, lithium ions move between electrode materials, enabling energy storage. However, aging mechanisms like lithium plating can negatively impact battery performance and lifetime. READ MORE

  5. 9. Reaction of Copper and Copper(I) Iodide with Iodine and Strong Field Ligands

    University essay from KTH/Tillämpad fysikalisk kemi

    Author : Aya Ali; [2022]
    Keywords : in films; AFM; copper iodide; solar cells; transparent conductive films; tunnfilm; AFM; koppar jodid; solceller; transparent ledande film;

    Abstract : Perovskit solceller (PSCs) är kända som 'ljusomvandling' enheter med ökad omvandlingseffektivitiet (PCE). PSCs är kända för detta flexibilitet och hög tolerans mot defekter och består av fem lager med olika material och egenskaper. READ MORE

  6. 10. Development of covalent organic frameworks for energy storage applications : DAAQ-TFP COF and MXene composite electrodes for proton cycling

    University essay from Uppsala universitet/Nanoteknologi och funktionella material

    Author : Simanjit Singh; [2022]
    Keywords : covalent organic framework; DAAQ-TFP; MXene; composite electrodes; 1 3 5-Triformylphloroglucinol; 2 6-Diaminoanthraquinone; nanosheets; exfoliation; ex-situ; Ti3C2Tx;

    Abstract : The demand for today's material resources for energy storage is rapidly increasing and can result in both environmental and political conflicts that can affect the development of electronic devices due to high prices and limitations of raw materials for batteries. In this study, potential future composite electrodes were synthesised with an ex-situ approach by compositing redox-active 2,6-Diaminoanthraquinone and 1,3,5-Triformylphloroglucinol covalent organic framework (DAAQ-TFP COF) with conductive delaminated Ti3C2Tx MXene to maximise the number of redox-active moieties during cycling.
