Study of electrolytic materials for the development of innovative energy storage devices

The aim of the PhD thesis is to study innovative, non conventional electrolytes, in order to improve the safety and reliability of Li-ion batteries. This work is structured in three main parts: 1. Development and characterization of Ionic Liquid-based electrolyte solutions 2. Development and characterization of Fluorine-free salt-based electrolytes 3. Development and characterization of Gel polymer electrolytes, using solution developed at point 1) and 2). During this work, thanks to a cooperation with Saes Getters S.p.A of Milan, the safety issue were also investigated from a technological point of view. In fact some electrochemical investigation were performed on a particular safety system, getter, that can adsorb gases released in batteries or supercapacitors.
