“That new battery shown will likely be in production by 2021”
How much better is the new one than the current one?
I watched the presentation, while doing other things, but got the gist of it. The new battery, along with other improvements promises to be 50 percent cheaper while perhaps doubling the range. Key phrase is "along with other improvements". The battery itself, will allow an increase in power over the old battery, due to more efficient packing into less space, and creates much less heat while fast charging. The new battery is a really big improvement - more power, cheaper to produce, generates less heat, and the ingredients are more available. The cost per kWh will be halved in the next year or two only if the "other improvements" are done. I think this is what spooked investors; they're unsure how soon the "other improvements" can happen despite promises of it happening in the next two years.
Drops 11% weight from battery pack, as the new cells provide structural strength. Adds 15% more energy storage in same space. Cell electrical current path reduced by 80% for lower dissipation—internally generated heat. Will deliver a range rating in excess of 500 miles.
