Dynamic charge acceptance and hydrogen evolution of a new MXene additive in advanced lead-acid batteries via a rapid screening three-electrode method

A methodology to screen additives in lead-acid batteries is critical. We developed a three-electrode system that can rapidly check the dynamic charge acceptance (DCA) and hydrogen evolution of electrodes. The electrode with 2% MXene and 0.2% carbon black shows a better DCA, which indicates its great...

Zusammenfassung:A methodology to screen additives in lead-acid batteries is critical. We developed a three-electrode system that can rapidly check the dynamic charge acceptance (DCA) and hydrogen evolution of electrodes. The electrode with 2% MXene and 0.2% carbon black shows a better DCA, which indicates its great potential in the start-stop technology.
