  ABSTRACT: In this paper we report the results of combined cycle- and life-aging and abuse tests carried out under severe conditions on Li4Ti5O12/LiFePO4 lithium-ion stacked prototypes using a PYR14 FSI-LiTFSI ionic liquid electrolyte. No relevant degradation phenomena took place within ionic liquid electrolyte during prolonged inactivity period or overcharging. No fire/explosion or venting event as well as no gas development occurred during abuse tests, which led only to modest raise in temperature. Therefore, electrodes based on Li4Ti5O12 and LiFePO4 active materials can be favorably combined with non-volatile and non-flammable pyrrolidinium FSI ionic liquid electrolytes to realize highly safe lithium-ion battery systems.
