3. Li-ion titanate technology for SLI battery applications in commercial vehicles
Master-uppsats, KTH/KemiteknikSammanfattning : Litiumjon-batterier har blivit väldigt populära för tillämpning i fordon. Den här teknologin har fler olika kemier att erbjuda som kontinuerligt förbättras. Litium-titanat-oxid-batterier använder (LTO) LTO som anod och erbjuder långt cyklingsliv samt minskar risk för SEI-bildning och litiumplätering. LÄS MER
4. Feasibility Study of the Decarbonisation and Electrification of a Commuter Ferry in Stockholm city
Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Sammanfattning : There is a need for alternative marine fuels and propulsion techniques in order to reduce the environmental and climate impacts of the transport sector, and meet the new Swedish climate targets of net zero emissions by 2045. There are several projects and studies on full electric ferries, while the option of hydrogen fuel cell-battery hybrids are not as well explored. LÄS MER
5. Low temperature Li-ion battery ageing
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för kemi - ÅngströmSammanfattning : Different kinds of batteries suit different applications, and consequently several different chemistries exist. In order to better understand the limitations of low temperature performance, a Li-ion battery chemistry normally intended for room temperature use, graphite-Lithium Iron Phosphate, with 1 M LiPF6 ethylene carbonate:diethylene carbonate electrolyte, is here put under testing at -10°C and compared with room temperature cycling performance.
