Mixed ionic-electronic conductivity of high-nickel, single-crystal cathodes influencing the cycling stability of all-solid-state lithium-ion batteries

Abstract
Removing cobalt lowers the electronic conductivity of high-nickel cathodes. A mismatch between electronic and ionic conductivities in the cathode composite leads to reaction inhomogeneity and peculiar cycling behavior in all-solid-state batteries.
