From: An in-situ gas chromatography investigation into the suppression of oxygen gas evolution by coated amorphous cobalt-phosphate nanoparticles on oxide electrode

Figure 6

In-situ GC results of O2 gas evolution plotted as a function of charging time based on (a) their initial voltage profiles and (b) amount of oxygen gas as a function of charging step potentials for the pristine OLO and a-CoPO4 coated OLO electrodes. A schematic that explains the mechanism for oxygen gas suppression and the electrochemical reaction with lithium during (c) charging and (d) discharging of the a-CoPO4 coated OLO cathode.
