TU Graz researchers identify singlet oxygen as major cause of deleterious side reactions in Li-air batteries; suggested approach to counter

Green Car Congress

Researchers led by a team from Graz University of Technology (TU Graz) in Austria have shown that singlet oxygen ( 1 O 2 ) forms in the cathode of a Li–O 2 battery during discharge and from the onset charge, and that it is responsible for a major fraction of side products that cause fast ageing in the battery.
