  1. 1. A comparison between aqueous and organic electrolytes for lithium ion batteries

    University essay from KTH/Kemiteknik

    Author : Gabriel Quintans De Souza; [2021]
    Keywords : batteries; electrolyte; lithium-ion; impedance spectroscopy; aqueous based electrolyte; batterier; elektrolyt; lithiumjon; impedansspektroskopi; vattenbaserad elektrolys;

    Abstract : Många batteriers användningsområden kräver att batterierna har hög upp- och urladdningshastighet samt låg kostnad. För dessa användningsområden är vattenbaserade laddningsbara batterier (ARB) ett möjligt alternativ i och med att de är svårantändliga, har god jonledningsförmåga, lägre inre resistans, billigare elektrolytlösning och tillverkning och har potentiellt högre upp- och urladdningshastigheter.

  3. 2. A study of poly(vinyl alcohol) as a solid polymer electrolyte for lithium-ion batteries

    University essay from Uppsala universitet/Strukturkemi

    Author : Gustav Ek; [2016]
    Keywords : ;

    Abstract : The use of solid polymer electrolytes in lithium-ion batteries has the advantage in terms of safety and processability, however they often lack in terms of performance. This is of major concern in applications where high current densities or rapidly changing currents are important. READ MORE

  4. 3. Towards Stable Li-metal electrodefor rechargeable batteries

    University essay from Uppsala universitet/Strukturkemi

    Author : Julia Morát; [2016]
    Keywords : Lithium metal; Battery; Dendrites; light microscopy; Adiponitrile; Al2O3;

    Abstract : Different types of alumina containing coatings were made on lithiumand copper in the purpose to mechanically hinder the growth ofdendrites. Lithium, coated with polymer-alumina composites wereplaced in symmetric cells for in situ studies by a light microscope. READ MORE

  5. 4. Synthesis of polycarbonate polymer electrolytes for lithium ion batteries and study of additives to raise the ionic conductivity

    University essay from Uppsala universitet/Strukturkemi

    Author : Jonas Andersson; [2015]
    Keywords : battery materials; polymer electrolyte; PTMC; poly trimethylenecarbonate ; LiTFSI; nanofillers; batterimaterial; polymerelektrolyt; PTMC; polytrimetylkarbonat; LiTFSI; nanofillers;

    Abstract : Polymer electrolyte films based on poly(trimethylene carbonate) (PTMC) mixed with LiTFSI salt in different compositions were synthesized and investigated as electrolytes for lithium ion batteries, where the ionic conductivity is the most interesting material property. Electrochemical impedance spectroscopy (EIS) and DSC were used to measure the ionic conductivity and thermal properties, respectively. READ MORE

  6. 5. Synthesis and characterisation of solid low-Tg polymer electrolytes for lithium-ion batteries

    University essay from Uppsala universitet/Institutionen för kemi - Ångström

    Author : Erik Törmä; [2014]
    Keywords : Electrolyte;

    Abstract : Electrolytes of poly(trimethylene carbonate-co-ε-caprolactone), poly(TMC-co-CL), and LiTFSI have been prepared and characterised. The copolymers were analysed with GPC and NMR, which showed that random high molecular weight copolymers of desired compositions had been obtained. READ MORE
