7. 5. Molecular Interactions and Dynamics in Lithium Conducting Electrolytes

   Författare :Josefina Adebahr; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ab initio calculations; plastic crystals; nanocomposite polymer electrolytes; NMR; Raman spectroscopy; gel electrolytes; polymer electrolytes;

   Sammanfattning : Lithium conducting electrolytes, suitable for battery applications, have been characterized on a molecular level using Raman spectroscopy, ab initio calculations and nuclear magnetic resonance spectroscopy, in order to better understand molecular and ionic interactions and dynamics in the systems. Three different types of electrolytes have been investigated; polymer gel electrolytes, solid polymer electrolytes and plastic crystal materials, with the main focus on the polymer based electrolytes.
