EVTV..Jack Ricard..has posted a rambling Youtube with an explanation why Battery Day has been repeatedly delayed.
He suggests Tesla cannot anounce a new improved, capacity, mileage, cost, etc... battery until they are in full production and installing them in cars, or it would kill sales of current stock and production.
Personally, i do not see the improved “million mile” battery as a huge benefit to the EVs..(.unless it is dramatically cheaper ?)...who wants a car battery to last 10-15+ years ?
However, extended life would be a huge boost for Teslas Storage products where life expectancy is a major factor in cost justification and ROI for utilities.
Musk has said he believes the Storage business could become bigger than the EVs , so being able to make one sale of 100MWh or a GWh of Power Packs with double the life potential, has to be a easier game than selling 10,000 cars.
And at the $750/kWh going rate for PowerPack storage, it likely more profitable.
So maybe he will launch the “new battery technology” as a storage product only initially ?
