High capacity surface route discharge at the potassium-O 2 electrode (2018)
Journal Article
Chen, Y., Jovanov, Z. P., Gao, X., Liu, J., Holc, C., Johnson, L. R., & Bruce, P. G. (2018). High capacity surface route discharge at the potassium-O 2 electrode. Journal of Electroanalytical Chemistry, 819, 542-546. https://doi.org/10.1016/j.jelechem.2018.03.041

Discharge by a surface route at the cathode of an aprotic metal-O2 battery typically results in surface passivation by the non-conducting oxide product. This leads to low capacity and early cell death. Here we investigate the cathode discharge reacti... Read More about High capacity surface route discharge at the potassium-O 2 electrode.

Kinetics of lithium peroxide oxidation by redox mediators and consequences for the lithium–oxygen cell (2018)
Journal Article
Chen, Y., Gao, X., Johnson, L. R., & Bruce, P. G. (in press). Kinetics of lithium peroxide oxidation by redox mediators and consequences for the lithium–oxygen cell. Nature Communications, 9, https://doi.org/10.1038/s41467-018-03204-0

Lithium–oxygen cells in which lithium peroxide forms in solution rather than on the electrode surface, can sustain relatively high cycling rates but require redox mediators to charge. The mediators are oxidised at the electrode surface and then oxidi... Read More about Kinetics of lithium peroxide oxidation by redox mediators and consequences for the lithium–oxygen cell.

Operando monitoring of the solution-mediated discharge and charge processes in a Na-O2 battery using liquid-electrochemical Transmission Electron Microscopy (2018)
Journal Article
Lutz, L., Dachraoui, W., Demortière, A., Johnson, L. R., Bruce, P. G., Grimaud, A., & Tarascon, J. (in press). Operando monitoring of the solution-mediated discharge and charge processes in a Na-O2 battery using liquid-electrochemical Transmission Electron Microscopy. Nano Letters, 18(2), https://doi.org/10.1021/acs.nanolett.7b04937

Despite the fact that in sodium-oxygen (Na-O2) batteries show promise as high-energy storage systems, this technology is still the subject of intense fundamental research, owing to the complex reaction by which it operates. To understand the formatio...
