Oxide ion conductors are an exciting class of materials with applications in various domains. Here, the authors show that Dion–Jacobson Phases are a structure supporting high O2− mobility. The bulk conductivity of CsBi2Ti2NbO10−δ even exceeds that of YSZ, offering new possibilities in electrolyte discovery.
