Abstract: A storage medium and an inert material, either integrated into the storage medium or existing as a separate phase in the storage medium, form a storage structure. The inert material at least partially contains or is formed by a polymorphous inert material. The polymorphous inert material has at least one polymorphous phase transition in the range between ambient temperature and maximum operating temperature of the solid electrolyte battery. The polymorphous phase transition induces a distortion of the lattice structure of the inert material, thus causing a change in the specific volume and acting on the surrounding grains of the storage medium. A mechanical coupling of the stresses triggered by the phase transition of the inert material causes the neighboring grains of the storage medium to break apart, such that new reactive zones become available in the storage medium, thereby regenerating the solid electrolyte battery.
