Further to the NMC cells now under development at Dr. Jeff Dahn's laboratory in Halifax, the latest published test results show no degradation of the cells over the last several thousand cycles: That's right: the cells appear effectively to have stopped aging, and are cycling 4x daily with well over 90% of their Day-0 capacity.
Further, due to additonal research done by a grad student at this lab, these cells may have a shelf-life of 100 years: (no parasitic side-reactions are occurring)
In fact, newly-hired scientists at Dr. Dahn lab have recently added new test equipment at the cell-test facility to monitor 'out-gassing' of cells, which seems to be a directly-measurable by-product of the side-reactions associated with cell degradation. Significantly, the NMC 5-3-2 cells now under test don't show this off-gassing:
Fast-forward to the end-game: what if Tesla announced a 20-year warranty on it's new Cybertruck battery packs? What if it announced a hundred?! (well, seriously...) Or how about a 4-million mile warranty on Semi batteries? The economic implications for the logistics industry are mind-bogglingly good. Perhaps half the cost of a diesel semi? Or is it 1/4?
Cheers to the Scientists!
