Chemical and morphological insights on the initial lithiation and delithiation of SiO2 anodes for Lithium-ion Batteries
Hjelseng, Kristianne Nilsen-Nygaard (Master thesis, 2023)Litium-ion batterier (LIB-er) dominerer batterimarkedet for bærbare elektroniske enheter og har en utbredt anvendelse i det voksende markedet for bilindustrien og stasjonær energilagring. De mest vanlige katodematerialene ... -
Insights on microstructural evolution and capacity fade on diatom SiO <inf>2</inf> anodes for lithium-ion batteries
Hua, Weicheng; Nylund, Inger-Emma; Cova, Federico Hector; Svensson, Ann Mari; Blanco, Maria Valeria (Peer reviewed; Journal article, 2023)is a promising material for developing high-capacity anodes for lithium-ion batteries (LIBs). However, microstructural changes of anodes at the particle and electrode level upon prolonged cycling remains unclear. In this ... -
LLZO as a Solid Electrolyte for Next Generation Batteries and their Potential Application in Electrical Vehicles
Zlatic, Ivana (Bachelor thesis, 2022)Faststoff-batterier anses å være oppfølgeren til konvensjonelle flytende elektrolyttbatterier, til og med forventet å overgå dem når det gjelder kapasitet, sikkerhet og levetid. Dessverre står denne teknologien overfor ... -
Thermal expansion of SrxBa1−xNb2O6 across and above the ferroelectric phase transition
Pedersen, Viviann Hole; Chavez Panduro, Elvia Anabela; Hua, Weicheng; Michaelsen, Marcus Grand; Chernyshov, Dmitry; Walker, Julian Bradley; Grande, Tor; Einarsrud, Mari-Ann (Peer reviewed; Journal article, 2024)Lead-free SrxBa1−xNb2O6(SBN) is of interest due to flexible chemistry, ferroelectric behavior, and electro-optic properties. The thermal expansion coefficient for SBN is reported only for compositions x = 0.35–0.59 and ...
