ELON MUSK UNVEILS TESLA NEW 4680 BATTERY GEN 3 WITH BIG UPGRADE

EV Channels Review

This video details Tesla's advancements with the 4680 battery, focusing on the upcoming Gen 3. The primary innovation discussed is the successful implementation of a dry electrode coating process for both anode and cathode, a significant upgrade from the previous wet coating method. This new process promises substantial cost reductions (potentially hundreds of dollars per Cybertruck), a 10x decrease in factory footprint and energy consumption, and improved energy density. The review highlights that while Gen 2 4680 cells are currently used in the Cybertruck, Gen 3 aims for even higher energy density, potentially reaching 300-500 Wh/kg compared to the current 232-244 Wh/kg. The video also touches on the potential use of manganese-rich cathodes to further boost energy density and longevity, though acknowledges challenges with degradation. Real-world testing of a Gen 3 battery in a Cybertruck has begun, with mass production of these batteries for the Cybertruck slated for Q4 of this year. Production of 4680 cells is ramping up, with Tesla aiming for cost parity with LFP batteries by year-end and a breakthrough year in 2025.
