Three-dimensional microbattery and method for the production thereof |
摘要 |
<p>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. A porous partition wall, which is impregnated with the electrolyte and prevents a passage of active electrode mass, is located between the two chambers. The free surfaces of the active mass of both electrodes and the partition wall lie in a plane with the surface of the substrate. The electrodes and the partition wall are hermetically sealed by a cover layer, which projects beyond the edge of the depression.</p> |
