"short circuiting and failure caused by mechanical stress creating and expanding cracks in ceramic electrolyte... Solutions: Use same mechanical forces to toughen material during manufacturing, much like a blacksmith anneals a blade during production... also, coat the electrolyte surface to prevent cracks or repair them if they emerge"
