Hydroperoxide-Mediated Degradation of Acetonitrile in the Lithium–Air Battery (2023)
Journal Article
McNulty, R. C., Jones, K. D., Holc, C., Jordan, J. W., Bruce, P. G., Walsh, D. A., …Johnson, L. R. (2023). Hydroperoxide-Mediated Degradation of Acetonitrile in the Lithium–Air Battery. Advanced Energy Materials, 13(3), Article 2300579. https://doi.org/10.1002/aenm.202300579

Understanding and eliminating degradation of the electrolyte solution is arguably the major challenge in the development of high energy density lithium–air batteries. The use of acetonitrile provides cycle stability comparable to current state-of-the... Read More about Hydroperoxide-Mediated Degradation of Acetonitrile in the Lithium–Air Battery.

Competitive Oxygen Reduction Pathways to Superoxide and Peroxide during Sodium-Oxygen Battery Discharge (2022)
Journal Article
Jovanov, Z. P., Lutz, L., Lozano, J. G., Holc, C., Gao, X., Grimaud, A., …Bruce, P. G. (2022). Competitive Oxygen Reduction Pathways to Superoxide and Peroxide during Sodium-Oxygen Battery Discharge. Batteries & Supercaps, Article e202200055. https://doi.org/10.1002/batt.202200055

The sodium-air battery offers a sustainable, high-energy alternative to lithium-ion batteries. Discharge in the cell containing glyme-based electrolytes can lead to formation of large cubic NaO2 particles via a solution-precipitation mechanism. While...

Critical Role of the Interphase at Magnesium Electrodes in Chloride-Free, Simple Salt Electrolytes (2021)
Journal Article
Holc, C., Dimogiannis, K., Hopkinson, E., & Johnson, L. R. (2021). Critical Role of the Interphase at Magnesium Electrodes in Chloride-Free, Simple Salt Electrolytes. ACS Applied Materials and Interfaces, 13(25), 29708-29713. https://doi.org/10.1021/acsami.1c06130

Magnesium (Mg) batteries are a potential beyond lithium-ion technology but currently suffer from poor cycling performance, partly due to the interphase formed when magnesium electrodes react with electrolytes. The use of magnesium bis(trifluoromethan... Read More about Critical Role of the Interphase at Magnesium Electrodes in Chloride-Free, Simple Salt Electrolytes.

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.
