Argonne National Lab Breakthrough Cathode Innovation for Sodium-Ion Batteries

Argonne National labs has a new cathode material for sodium-ion batteries. Johnson’s team invented a layered oxide cathode tailored for sodium-ion batteries. This variation on the NMC cathode is a sodium nickel-manganese-iron (NMF) oxide with a layered structure for efficient insertion and extraction of sodium. The absence of cobalt in the cathode formula mitigates cost, …

Tesla 4680 Battery Chemistry Upgrade for 20% Energy Improvement in First Half of 2024

Joe Tegtmeyer described the Telsla 4680 battery chemistry upgrade. At the end of 2023, the 4680 battery chemical composition ratios in Cathode material was NMC 811 (80% Nickel, 10% Lithium, 10% Cobalt). However, Tesla is finishing the process of transitioning over to NMC 955 now that we are in 2024. They are also trialing asymmetric …

Tesla Multiple 4680 Production Lines Ramp in 2024

The Tesla 4680 production ramp has taken about two years longer than Tesla first planned. Most of the analysis has been based upon monthly or quarterly percentage increases in production. This has been while the technical problems were being solved. The 4680 technical problems should be completely solved by mid-2024. The second Texas line was …

Billions for Everyone From Self-Replicating Factories

Humanity needs to simplify the technology and products for our civilization but make them fully scalable and self-replicating. The technologies that we pick to scale need to be ones that we can increase to a thousand times our current levels with manageable pollution and side-effects at those scales. We will soon have billions or trillions …
