1. Graphene Based Aqueous Ammonium Dual-Ion Batteries
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/StrukturkemiSammanfattning : The global transition to renewable energy sources is placing high demands on the development of effective energy storage methods, the most prevalent being batteries. Dual-ion batteries are a new battery technology that takes advantage of the simultaneous intercalation of both cations and anions. LÄS MER
2. Investigation of stability in high salt polymer electrolytes for sodium batteries
Master-uppsats, Uppsala universitet/StrukturkemiSammanfattning : Poly(trimethylene carbonate)–sodium bis(fluorosulfonyl)imide system shows a promising performance as polymer-in-salt electrolytes. The polymer electrolytes with salts concentration from 62% to 71% were tested through DSC, FTIR, EIS and constant current cycling. The solubility of the salts varies in different salts in PTMC.

3. EFFECT OF TUNING THE SURFACE OF LLZO PARTICLES ON THE PERFORMANCE OF CERAMIC –POLYMER COMPOSITE ELECTROLYTES
Master-uppsats, Uppsala universitet/Strukturkemi; Uppsala universitet/Oorganisk kemi; Uppsala universitet/Fysikalisk kemiSammanfattning : Liquid based electrolytes are known to have safety issues and for their low volumetric energy densities to meet the future energy storage demand. Solid electrolytes based on ion conducting solid ceramic and solid polymer electrolytes are being studied and considered as an alternative to alleviate the issues with liquid electrolytes. LÄS MER
4. Barrier properties of model coatings using recycled iron oxide pigment
Uppsats för yrkesexamina på grundnivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Sammanfattning : The aim of this study was to compare the barrier properties of organic coatings with the same polymer matrix but different types of iron oxide particles, commercial and recycled. The work was carried out for the company SSAB with the aim of investigating whether the pigment Merox ferric oxide, which is produced in-house at the company during the pickling process, can be used and replace commercial iron oxide pigment.

5. Structural Battery Electrolytes
Kandidat-uppsats, KTH/Fiber- och polymerteknologiSammanfattning : Strukturella batterier är multifunktionella; de tillhandahåller lagring av elektrokemisk energi samtidigt som de bidrar med en lastbärande funktion. Tillsammans möjliggör detta att batteriet kan integreras i karossen hos ett elektriskt fordon eller apparat. LÄS MER
