It Happened! Elon Musk LEAKED Tesla’s Dry Cathode 4680 Battery to Make EVs Cheaper & Better! Imagine a battery that slashes production costs by 50% and shrinks the number of cells needed from 4,400 to just 960. By eliminating traditional tabs and optimizing electron flow. This isn't just an upgrade—it's a game-changer that could redefine the future of electric cars. What makes Tesla's 4680 dry cathode battery a breakthrough in EV technology?

Tesla is currently using 4680 cells to produce structural battery packs for the Model Y. However, these vehicles have encountered issues with poor charging performance and low energy density, leading to their swift removal from the sales catalog. The large size of the 4680 cells makes cooling difficult, limiting the battery's performance. These problems have become apparent, and Tesla recognizes the need for immediate improvements.
A key factor in this improvement is the dry process. The dry process (Dry Battery Electrode, DBE) is fundamentally different from the wet process (Wet Battery Electrode, WBE) currently in use. The dry process eliminates hazardous solvents and the oven firing process, saving time and space, and is more environmentally friendly.
It Happened! Elon Musk LEAKED Tesla’s Dry Cathode 4680 Battery to Make EVs Cheaper & Better! Specifically, the dry process is used to produce the anodes of the battery—the conductive electrodes at the edges of the cell—rather than the wet process used previously. Tesla's 4680 cell suppliers, including LG and Panasonic, are working to reduce costs and increase the production of 4680 cells. If Tesla can effectively scale the dry anode method, the production of 4680 cells and battery packs will become cheaper and more efficient.
