2. 1. Operando Characterisation of Lithium–Sulfur Batteries

   Author : Yu-Chuan Chien; Daniel Brandell; Matthew Lacey; Paul Shearing; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; lithium–sulfur batteries; operando characterisation; intermittent current interruption; X-ray diffraction; small-angle scattering; electrochemical impedance spectroscopy; Chemistry with specialization in Inorganic Chemistry; Kemi med inriktning mot oorganisk kemi;

   Abstract : Lithium–sulfur (Li–S) batteries have been under the spotlight of research on electrochemical energy storage systems, primarily owing to their high theoretical specific energy (2552 Wh kg-1). So far, Li–S cells on the market have presented a specific energy of 400 Wh kg-1, which is superior to many commercial alternatives, but far below the theoretical value. READ MORE

4. 2. Fundamental Insights into the Electrochemistry of Tin Oxide in Lithium-Ion Batteries

   Author : Solveig Böhme; Leif Nyholm; Kristina Edström; Laure Monconduit; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Tin; Tin oxide; Lithium-ion batteries; Electrochemistry; High temperature cycling; Conversion reaction; XPS; SEM; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

   Abstract : This thesis aims to provide insight into the fundamental electrochemical processes taking place when cycling SnO2 in lithium-ion batteries (LIBs). Special attention was paid to the partial reversibility of the tin oxide conversion reaction and how to enhance its reversibility. READ MORE
