Lithium oxygen batteries show a very high theoretical gravimetric energy density which makes them an attractive candidate for high energy batteries to enable long-distance electric driving and mass market penetration of electric vehicles. Before commercialization many challenges need to be solved. In our talk we discuss lithium (alkyl) carbonate formation as possible reason for the increasing overpotential during charge. Besides, we show that gas analytics during cycling is crucial for electrolyte research which is of fundamental importance to improve cycleability of lithium oxygen batteries.
