Recently, sources revealed that Tesla is pushing forward its largest battery project in 21 years since its establishment, planning to launch four new 4680 battery models by 2026. It is reported that Tesla is designing these four new proprietary batteries to power the electric truck Cybertruck, the autonomous Robotaxi, and other electric vehicles.
This marks the largest number of battery projects the company has undertaken at the same time to date. Tesla introduced the 4680 battery model in September 2020, aiming to create a battery that improves energy density while reducing costs. Tesla’s CEO Elon Musk first outlined at that time plans for Tesla’s next-generation battery production line, named 4680 because each cylindrical battery cell has a diameter of 46 millimeters and a length of 80 millimeters. And Musk stated that this battery would enable Tesla to produce affordable electric vehicles priced at just $25,000, with increased production of the 4680 battery considered key to lowering costs across the company’s entire product line.
Despite facing challenges with low production yield, Tesla is still advancing the production of the 4680D battery and has set a goal to increase the yield to 90% by the end of this year. The company plans to achieve mass production by Q2 of 2025 and launch four subsequent versions of the dry cathode 4680D battery in 2026.
Among these, the battery codenamed NC05 will be used in the Robotaxi. Additionally, the NC20 battery will be utilized in SUVs and the Cybertruck, while the NC30 and NC50 will be Tesla’s first batteries to incorporate silicon-carbon materials in the anode. These batteries will be assigned to different vehicle models to meet the diverse needs of various types of cars.
