1. Towards Safer Lithium-Ion Batteries
Sammanfattning : Surface film formation at the electrode/electrolyte interface in lithium-ion batteries has a crucial impact on battery performance and safety. This thesis describes the characterisation and treatment of electrode interfaces in lithium-ion batteries. LÄS MER
2. Cladophora Cellulose-based Separators for Lithium Batteries
Sammanfattning : The development of lithium-ion batteries (LIBs) has been focused on exploring and improving the electrode materials and electrolytes in the past decades. An indispensable component, the separator, is however not studied as extensively. In general, a separator has two functions, i.e. LÄS MER
3. Tools for characterizing performance degradation in lithium-ion batteries
Sammanfattning : Lithium-ion batteries have enabled vast societal changes, ranging in scale from the adoption of personal electronics to electromobility and grid-scale, renewable energy storage. However, all applications face performance fade over time, observed as losses of battery capacity and power. LÄS MER
4. De nordiska lekarna : Grannländer i pressen under olympiska vinterspel
Sammanfattning : Throughout the 20th century, Nordic audiences consumed mediations of athletes from their own country who were competing against Nordic neighbours at Olympic winter games. In daily newspapers, coverage of the games continuously related to notions of both Nordic and national identities, as well as of the imagined relationship between them. LÄS MER
5. From behaviour to genes: anti-predator responses of brown trout (Salmo trutta) under winter conditions
Sammanfattning : Temperature has major effects on the performance of poikilotherms. In encounters with predators, low winter temperatures constrain predator detection and escape capabilities in prey fishes. LÄS MER
