Abstract
A method and apparatus comprising a manufacturing process, equipment and a product. The manufacturing process and equipment configured to produce very high precision parts using a laser beam. Embodiments of the manufacturing process and equipment provide an improved method for the production of supercapacitors with critical dimensions on the order of one to fifty microns that can store electricity at very high energy densities using a modified laser beam. Using the manufacturing process and equipment, the proposed improvements allow the production of key parts thousands of times faster than what can be achieved using the usual process, resulting in a manufacturing time suitable for mass production.
Claims18
A filtering device for the collimation of a laser beam suitable for the production of high-density supercapacitors having high energy capacity comprising:
- a sealant layer;
- a substrate;
- a plurality of filtering patterns, each filtering pattern comprising a pattern formed by a plurality of gaps formed within the sealant layer, the gaps designed to allow the laser beam to pass through the sealant layer and produce cuts on the substrate;
- wherein the plurality of filtering patterns are placed at variable distances to each other in perfect alignment so that when seen from the point of view of the incident laser beam all filtering patterns are seen as a single filtering pattern and correspondent gaps in the filtering patterns are seen as a single gap;
- wherein the filtering device is configured to reflect or absorb portions of a laser beam that enter the plurality of filtering patterns at diversion angles non-perpendicular to the plurality of filtering patterns and at angles greater than the angle allowed by the edges of correspondent gaps in the first and last filtering pattern and smaller than a maximum diversion angle of the laser source.
A method for the production of a supercapacitor using a filtering device and laser, comprising:
- forming a plurality of filtering patterns with gaps in the intended pattern to be created;
- aligning the plurality of filtering patterns with a laser source;
- aligning a substrate to the plurality of filtering patterns;
- emitting a laser beam from the laser source;
- reflecting or absorbing portions of the laser beam that encounter a reflective or absorptive structure in any of the plurality of filtering patterns;
- cutting the substrate with the portion of the laser beam entering the gaps to produce the pattern contained in the filtering patterns, resulting in a structure with a first terminal and a second terminal of a supercapacitor.
