2. 1. Probing Critical Interfaces in Dual-Ion Batteries : The Road Towards Performant Graphite Cathodes

   Author : Antonia Kotronia; Kristina Edström; Tobias Placke; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; dual-ion batteries; graphite; cathode-electrolyte interface;

   Abstract : Transitioning into a zero-emission society will require massive efforts with respect to the harnessing and storage of renewable energy resources. The development of large-scale, electrochemical energy storage systems based on abundant and environmentally benign compounds is seen upon as a key factor for guaranteeing a successful outcome.

   Abstract : Lithium-ion batteries (LIBs) have become reliable electrochemical energy storage systems due to their relative high energy and power density, in comparison to alternative battery chemistries. The energy density of current LIBs is limited by the average operating voltage and capacity of oxide-based cathode materials containing a variety of transition metals (TM). READ MORE

5. 3. Insights into Li-ion Battery and Stainless Steel Interfaces Using Refined Photoelectron Spectroscopy Methodology

   Author : Sara Malmgren; Kristina Edström; Håkan Rensmo; Daniel Abraham; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : If sacrificing some of its material to form a passivating layer at the surface, materials may expand the range of environments where they can be used and further material degradation can decrease. This thesis aims to contribute with insights into passivating layers on especially Li-ion battery anodes (solid electrolyte interphase, SEI) but also on stainless steels, as well as the non-passivating Li-ion battery cathode/electrolyte interface layers (solid permeable interface, SPI).
