AbstractWith a global transition towards electrification, there is considerable interest in the development of high energy density battery technologies. The current world leading battery chemistries, that are enabling the mass market electrification of transport, are high-nickel positive electrodes. However, as positive electrode nickel-content increases, so too does the reactivity of the positive electrode surface with the electrolyte species, limiting the long-term performance of these cell chemistries. The purpose of the first half of this thesis is to identify failure mechanisms and understand the feasibility of vinylene carbonate formation in cells containing a NMC811 electrode, with the objective of proposing actionable solutions to overcome current inefficiencies hindering research progress.
