PG, the fact that Tesla in the past has used NCA and this new development is in NMC is exactly why we are waiting for battery day. The excitement is that the Chinese Tesla models will use NMC batteries first, which then may expand into the US vehicles.

"CATL also has developed a simpler and less expensive way of packaging battery cells, called cell-to-pack, that eliminates the middle step of bundling cells. Tesla is expected to use the technology to help reduce battery weight and cost.

The sources said CATL also plans to supply Tesla in China next year with an improved long-life nickel-manganese-cobalt (NMC) battery whose cathode is 50% nickel and only 20% cobalt.

Tesla now jointly produces nickel-cobalt-aluminum (NCA) batteries with Panasonic (6752.T) at a “gigafactory” in Nevada, and buys NMC batteries from LG Chem (051910.KS) in China. Panasonic declined to comment.

Taken together, the advances in battery technology, the strategy of expanding the ways in which EV batteries can be used and the manufacturing automation on a huge scale all aim at the same target: Reworking the financial math that until now has made buying an electric car more expensive for most consumers than sticking with carbon-emitting internal combustion vehicles."
