Method of manufacturing a lithium battery

A method of manufacturing a battery with a substrate current collector, wherein the method comprises:

• forming an elongate and aligned electrically conductive structures on a substrate face with the electrically conductive structures having upstanding walls in relation to the substrate face;
• wherein the upstanding walls are formed with a first electrode layer covering said upstanding walls, a solid state electrolyte layer is provided on the first electrode layer;
• and wherein a second electrode is formed by covering the solid state electrolyte layer;
• and
• forming a top current collector layer in electrical contact with the second electrode,
• wherein the second electrode is shielded from the electrically conductive structures by an insulator covering a part of the electrically conductive structures adjacent an end side the electrically conductive structures to prevent an ion transport path between the first electrode layer and the second electrode, thereby mitigating stress build up near the end side of the electrically conductive structures.
