Abstract
An electrochemical device can include a cathode layer including an ionic conductor material and an electronic conductor material. The cathode layer can include a ratio of (Vi/Ve) of a volume of the ionic conductor material (Vi) to a volume of the electronic conductor material (Ve) of at least 1.3. In an embodiment, the cathode layer can include a median surface diffusion length (Ls) greater than 0.33 microns. In an embodiment, the cathode layer can include a cathode functional layer.
