Thanks for this. 10$/kWh would be insane as an aspirational number but are these manufacturer costs or grid scale buyer costs or retail costs for end user in EVs/homes? To make it more specific, what % drop in per-kwh costs for grid scale storage should energy developers expect to see over the next 2-3 years due to sodium ion? Trying to nail down a best-guess percentage drop to get a feel for how big this is going to be.
