ATO is a carbon-free support material
During the entire recharge, 83018 ppm O2 evolved in the OEMS cell, which equals 32.9 μmol O2, whereas the pressure loss of 51 bar during discharge corresponds to 46.91 μmol O2. Consequently, only 70% of the O2 consumed during discharge is released upon charge. This is explained by parasitic reactions during discharge and charge: During discharge, only 86 ± 6% of the capacity and the consumed oxygen go into the formation of Li2O2 and Li2O, with 14 ± 6% oxygen being used up in side reactions.
