(a) Molar ratio between oxygen gas generated and consumed during the first cycle of the Li-oxygen battery at 400 mA/ge at a fixed discharge capacity of 1 mAh (charging cut-off potential was 4.5 V vs. Li/Li+). (b) The first cycle voltage profiles that correspond to (a), MWCNT films, E-MWCNT films (~8.19 × 1010 E. coli cells) and S-MWCNT films (1.28 × 1011 E. coli cells). (c) Gas (O2, CO2, and H2) evolution rate profile during the first charging step of Li-oxygen battery corresponding to (b), measured by DEMS.
