Tesla builds first Cybercab with in-house cathode material
Tesla's Robotaxi account unveiled the first gold Cybercab built using cathode material from its own plant -- the first cathode production facility in the Americas -- a vertical-integration move that cuts costs on one of a battery cell's priciest components while tightening supply control.
Tesla's official Robotaxi account on X unveiled, on September 23, the first Cybercab built using in-house cathode material -- a gold-colored unit -- sourced from what the company described as the first cathode production facility in the Americas, located at Gigafactory Texas.
Cathode material is among the most expensive components in a battery cell. Producing it in-house rather than relying on external suppliers can lower costs and improve supply security -- a factor directly tied to the profitability of Cybercab, Tesla's purpose-built two-seat robotaxi.
Tesla had previously brought a cathode production line for its 4680 cells online at Gigafactory Texas; this announcement confirms that material has now made it into an actual production vehicle for the first time. Cutting battery costs through vertical integration has long been a core pillar of Tesla's strategy.
Cybercab is aimed at mass production next year as Tesla's dedicated robotaxi vehicle. For shareholders, improving the battery cost structure is one of the key variables in the unit economics of the robotaxi business, and this milestone is a signal of progress in that direction.
