GAS MANAGEMENT AS POSSIBLE SOLUTION FOR LONG-LIFE LI-ION BATTERIES

This research work has been aimed at developing an innovative analytical methodology, useful to reveal gaseous side products within Li-ion cells. The analytical protocol is based on the coupling of infrared spectroscopy and electrochemical techniques. Experiments have been carried out on Full Li-ion cell under resting and operative conditions. The time evolution of the most relevant gaseous product (CO2) has been monitored, revealing the conditions during which its generation is induced. The analytical information have been used to project and develop a specific scavenger for CO2 adsorption. The scavenger has been configured in order to be complaint to battery requirements and its reliability has been proved, under battery condition, by the means of an absorption volumetric bench.
