Did Tesla Acquihire A Colorado Battery Startup?

Louisville Colorado (just 20 minutes north of Denver), has become a hotbed for next generation EV batteries. Now Tesla is hiring for a 'Cell Technician' in the area to "assist anode development and optimization R&D." Additionally, the candidate is required to understand "electrode fabrication, delicate assembly of coin cells, cell dissection, running cell tests and data analysis & lab-scale electrode slurry mixing and electrode coating" .... Interesting! Could Tesla be partnering with one of these startups, Solid Power, Forge Nano or SilLion?
