The development of battery electric vehicles is critical in efforts to decarbonise transport and lithium-ion (Li-ion) batteries have become synonymous with this effort. As a result, much research has focused on developing high rate and capacity cathode materials for Li-ion batteries . The high nickel content in NMC811 (Li x Ni 0.8 Mn 0.1 Co 0.1 O 2 ) cathodes provides good performance by these metrics and the reduction in cobalt compared to other NMC family materials offers important supply chain benefits . However, these materials suffer from a wide range of degradation mechanisms that lead to capacity fade after many charge/discharge cycles. For example, undesirable phase transitions , increased transition metal dissolution , gas release , and the formation of cracks , have all been shown to lead to capacity fade, especially in nickel rich chemistries. Cracking in particular has been shown to be one of the primary considerations in capacity fade .
