摘要： A self-healing ceramic ion-selective membrane assembly including a ceramic ion-selective membrane, and at least one additive layer. The at least one additive layer includes an ionic ceramic material which is porous or ion-selective. The at least one additive layer having a metal cation diffusivity higher than the metal cation diffusivity of the ceramic ion-selective membrane. When a defect occurs through the ceramic ion-selective membrane, metal cation transport will be enhanced by orders of magnitude towards and into the defect, driven by the chemical or electrical potential difference between the two sides of the membrane.
