Tesla 4680s have had slower ramping because of problems with the Cathode needing a wet process and cathodes made by other companies. Auto experts Munro Associates have taken apart a cybertruck and they think a dry process was used for both the cathode and the anode. This may not be for all 4680 batteries and Tesla has deals with LG and some Chinese battery makers for 4680 cathodes. However, this could mean the scaling and ramping of 4680 will accelerate as a complete solution to the Tesla 4680s could be unfolding.
There is silicon in the anode and this will increase the energy density.
There is no manganese in these new 4680s. Munro thinks eliminating the manganese was needed to make the dry electrode process work for the cathode.
*breaking* @Tesla‘s new patent on 4680 cells (Dry energy storage device electrode and methods of making the same) is published today Jan 16th, 2024.
the patent shows how Tesla is using dry cathodes and/or anodes for the 4680 Cyber cells!!
