Abstract

The increasing demand of portable energy in terms of cycle life for electronic devices such as smartphones, tablets and computer or the high stability required for medical application and the high energy density for smart energy grids and electrified transport require a breakthrough in performance lower cost, safety and environmental compatibility. indeed, the conventional energy storage devices are characterized by limited specific capacity and energy density due to the intrinsically properties of the cathodic active materials i.e. LiCoO2 with specific capacity if 150 mAhg-1 and a theoretical energy density of 550 WhKg-1. therefore, the deep investigation and optimization of new classes of electrodes proposed in this work of thesis, may shed light on the possible candidates for a new generation of energy storage devices characterized by high energy density and environmental compatibility. Furthermore, one of the main topic of this work is the study of new classes of electrolytes characterized by low flammability and high ion mobility properties in order to ensure high performances and safety level
