While Tesla doesn't need more Chinese batteries that will prevent it from getting federal subsidies, it is still being tempted by the M3P invention that offers 20% higher energy density.https://www.notebookcheck.net/Tesla-to-use-CATL-s-breakthrough-M3P-battery-as-Elon-Musk-thought-manganese-has-potential.808561.0.html
The energy density increase is respectable. I wonder, does M3P also offer the same charging flexibility as LFP? One of the biggest advantages of LFP batteries is that they're not overly picky about state of charge vs. longevity.
