The Limiting Factor reports that Tesla will use Polycrystal cathodes with new coatings and dopants to enable cobalt-free batteries with greater energy density and more charge cycles. This will be about a 4% improvement in material cost and energy density. The main improvement will be about a 7% gain from factory process improvement.
Single Crystal cathodes would have greater energy density but would have higher costs.
