21. Toward Safer Energy Storage Solution by Development of Fluorine-Free Battery Electrolyte
Sammanfattning : Portable electronic devices such as mobile phones, laptops, cameras and electronic vehicles (EVs) which contain lithium-ion batteries (LIBs), are indispensable part of our modern society. The safety of conventional electrolytes of LIBs, composed of fluorinated lithium salts and organic solvents is the source of some concerns. LÄS MER
22. Tight-Binding Modelling of Deep Eutectic Solvent-Based Lithium Battery Electrolytes
Sammanfattning : In recent years, there has been a growing interest in utilizing liquid electrolytes such as deep eutectic solvents (DES) as electrolytes for lithium batteries, owing to their numerous advantageous properties, including ease of preparation, tunability, wide electrochemical stability windows, and low vapor pressures. However, an aspect that remains poorly understood is the intricate relationship between the local structural symmetry, entropy, and the macroscopic properties of DES electrolytes. LÄS MER
23. Microscopic Dynamics and Structure of some Polymer-based Electrolytes
Sammanfattning : The electrolyte is a key component in high-capacity lithium batteries and there is a large demand for improved materials to increase the performance. Polymer-based electrolytes offer advantages in the design of safer and lighter batteries. LÄS MER
24. Crystal structure studies of a new series of molybdovanadate polyanions and some related vanadates
Sammanfattning : The determination of complexes formed in weakly acidic aqueous solutions containing pentavalent vanadium as well as hexavalent molybdenum has proved diffi cui t due to slow equilibria and 1 imi ted sol ubi 1 i ty of especially the vanadium species. The formation of several different polynuclear complexes with a very varied molybdenum/vanadium ratio also complicates the interpretation of Potentiometrie data. LÄS MER
25. Self-Diffusion and Microstructure of Some Ionic Liquids in Bulk and in Confinement
Sammanfattning : An ionic liquid (IL) is a salt, which usually is in the liquid state at normal temperature and pressure. The properties of ILs can be adjusted for various processes and applications by choosing different combinations of ions. Similar to other salts, ILs contain only ions with positive (cations) and negative (anions) charges in equal proportions. LÄS MER
