Abstract: A three-dimensional microbattery is disclosed, in which a depression, in which two chambers lying adjacent to one another in the substrate plane are implemented, is provided in a substrate. The active mass, which is impregnated with an electrolyte, of negative and positive electrodes is received in each of the chambers.
