  2. 1. Characterization of Novel Electrolytes for Li-Batteries

    Author : Luis Aguilera Medina; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TFSI; pyrrolidinium; lithium ion battery; SAXS; organic solvent; Raman scattering; electrolyte; ionic liquid; imidazolium;

    Abstract : In a world that strives toward greener and more sustainable energy solutions, the need for suitable energy storage devices has brought Lithium-ion batteries (LIB) into focus of research. Although the Lithium-ion battery is a consolidated technology for portable applications, capacity, cost, and not the least safety aspects are major concerns when it comes to its implementation into large-scale energy storage applications, such as electric vehicles.
