Tesla plans to expand battery cell production at its Berlin-Brandenburg Gigafactory to an annual capacity of 18 GWh. Backed by $350 million in recent investments, the site in Grünheide is positioned to become one of the largest cell manufacturing facilities in Europe. To accelerate innovation, Tesla and the startup platform JUNI are launching the Battery Cell Giga Challenge, beginning in August 2026.
This program invites early-stage companies to showcase technologies that enhance industrial battery cell manufacturing in areas such as materials, production equipment, operations, automation and artificial intelligence. Selected applicants will present their solutions to Tesla’s cell production experts, advance to in-depth technical discussions and compete for paid pilot projects on the factory floor. Key evaluation criteria include real-world applicability, measurable improvements in quality, speed, cost, safety or scalability and validated proof of concept (for example, prototypes, test data or initial customer pilots).
The selection process comprises five phases: an initial online application outlining the manufacturing challenge addressed, the solution’s relevance and demonstrated results; a screening against Tesla’s production requirements; a technical interview to explore implementation scenarios; a pitch day before Tesla stakeholders; and final pilot negotiations. Startups are encouraged to keep proposals concise, fact-based and focused on three questions: What specific manufacturing problem do you solve? Why is your solution relevant? What proof points do you already have?
Applications are due by July 24, 2026. This challenge offers startups a unique opportunity to test and scale innovative cell production technologies within one of Europe’s most advanced gigafactories. Teams that secure paid pilots will collaborate directly with the Tesla cell-production team in Grünheide, working under real-world conditions to refine and deploy their solutions.
