The price is set by the market, not by the manufacturer.

This means that they won't really know the price until they find somebody willing to buy it. Before that it is just guesswork. If it costs more to produce then people are willing to spend then it won't last very long.

Which means "First commercially viable" part of the title is a bit of marketing propaganda wank. It might be or might not be commercially viable. This isn't something that gets to be decided by the manufacturer.

This is incorrect. The manufacturer can set a high price and target a high margin part of the market in exchange for lower demand.

It is not in the best interests of any business outside of a commodities producer to produce at absolute top volume and keep lowering price until demand absorbs it all.

Not necessarily. If they are confident they can build it in volume at a cost equal to or less than existing batteries, then by definition they are justified in calling it commercially viable.

The price is set by the market, and that process may happen to be too low to make the whole enterprise profitable. That's the question.
