Designing better batteries for electric vehicles

Note, the mass of an anode is at most 15% of mass of the modern battery cell.

All "metallic" lithium cells still need some mechanical structure to hold lithium. So, at most you will get a half of the mass of graphite, given that graphite is already a quite lightweight material.

For the cost, the second most expensive part in the cell after the cathode is the separator. Close to a third of cell's cost can be the separator. Japanese currently have a near monopoly on high-end separators, with Chinese having the rest of the market.

From where do the Korean battery manufacturers source their separators?

I have no idea honestly. One may think they may be trying to avoid Japanese suppliers, but who knows. The entirety of Korean semi-industry sits on Japanese consumables for example. Times change.
