1. Block Copolymer Electrolytes : Polymers for Solid-State Lithium Batteries
Sammanfattning : The use of solid polymer electrolytes (SPEs) for lithium battery devices is a rapidly growing research area. The liquid electrolytes that are used today are inflammable and harmful towards the battery components. LÄS MER
2. Sodium Batteries: From Liquid to Polymer Electrolytes
Sammanfattning : Today lithium-ion batteries (LIBs) are dominating the field of rechargeable batteries for portable devices. More recently LIBs have also been considered for large-scale applications, such as in the areas of electromobility and grid storage. LÄS MER
3. Molecular Interactions and Dynamics in Lithium Conducting 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.
