Abstract
In the present lithium ion technology large interest is focused on the development of battery systems characterized by a high degree of reliability and safety, especially in view of their prospected use in the hybrid vehicle market. In this respect, it appears mandatory to select electrodes having operating voltage evolving within the stability window of the electrolyte. In addition, high capacity, high rate, long cycle stability, low cost and environmental compatibility are also highly welcome characteristics. Finally, an extra step towards reliability and cell design modularity may be achieved by moving from the standard liquid-like electrolyte to a polymer electrolyte configurations. In this work, we have chosen some interesting electrodic materials and we have combined them with a PVdF based gel electrolyte in order to realize a safe, low cost and sustainable lithium ion polymer battery. The chosen anode materiale is based on TiO2(B) nanowires, while the cathode is either LiFePO4 or LiNi0.5Mn1.5O4.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
