Tesla to Launch Four New Battery Types by 2026 for EV Models

Tesla aims to enhance battery performance and production efficiency with new in-house designs, despite current manufacturing challenges.

Tesla plans to introduce four new versions of its 4680 battery cells by 2026, targeting models like the Cybertruck and the upcoming Robotaxi.
The company is working to overcome production issues, notably a high cathode defect rate in the new 4680 cells, compared to traditional methods.
A new dry cathode manufacturing process is being developed to improve efficiency and reduce environmental impact.
Tesla intends to start using the dry cathodes in Cybertruck batteries by mid-2025, with a production goal of 2,000 to 3,000 units per week.
The Robotaxi, set to be unveiled next week, will feature one of the new battery designs, reflecting Tesla's shift towards AI and autonomous technology.
