Abstract
Different discharge products were revealed in Li–O 2 batteries with different carbon cathodes by operando Raman and ex situ Raman and XPS measurements. In a carbon paper electrode Li 2 O 2 is formed, while for electrodes with CNT, Li 2 CO 3 and Li 2 O 2 were noticed in different discharge stages.
