Car appreciation... the aesthetics, the engineering, etc

No.

I would call it marginal gains from several different things (ie something achievable and not a lab tech that'll take decades to deliver).

First a new battery cell design, tab-less which reduces cost and also increase power / range, larger physically but without the heat issues that usually comes with.

Second, anode / cathode material changes that remove cobalt and improve electrode travel, increasing efficiency and decreasing cost.

Third, a change in the process from wet to dry rolling battery material which reduces the factory footprint, manufacturing process (and therefore cost) by an order of magnitude.

Finally, integration of cells into the vehicle architecture. Basically a single process for casting each half of a car, that allows you to integrate the cell into the physical floor of the car and glueing them in. Making the car lighter, with tighter packaging and higher rigidity whilst reducing cost and increasing potential capacity per car size (more cells for the same footprint).

Pretty exciting stuff that allows for scaling of battery production and massive capacity / footprint gains whilst improving cost and carbon efficiency.
