Tesla’s 4680 battery, once questioned as a “PPT technology”, has now witnessed a surge in mass production. The latest data shows that the cumulative production of this battery has exceeded 100 million units by September 2024. The weekly production capacity of the Texas factory is sufficient to equip 5,000 Model Y vehicles, and the yield rate has increased from 60% in the early stage to 92%, indicating that this technology has officially moved from the laboratory to large-scale application. More subversively, through breakthroughs in core technologies such as dry electrodes, the production cost has decreased by 40% compared with traditional batteries, and the floor space of the production line has been reduced by 70%.

The technological advantages of the 4680 battery are being converted into market competitiveness. Its tabless design reduces internal resistance by 70% and increases peak discharge capacity by 6 times. Combined with the CTC (Cell to Chassis) technology, it can reduce the vehicle weight by 10%, decrease the number of chassis components by 370, and further lower the cost by 15%. Industry giants have followed suit one after another. BMW announced that its new platform will fully adopt 46-series large cylindrical batteries in 2025. CATL’s Kirin Battery is compatible with this design, and LG Energy Solution has invested 5 billion US dollars in building an exclusive production line. Ping An Securities predicts that the global market size of 46-series large cylindrical batteries will exceed 100 billion yuan in 2025. This battery revolution led by Tesla is reshaping the global electric vehicle industry landscape.
