If the NY battery factory gets up and running. At 1 GWH prod and at a generous 10% profit it will still only make $10,000,000 per year. After paying the people who provided the capital etc. MNS shareholders would see stuff all. There is no way any of this makes commercial sense IMO.
The holy grail for ev battery makers is manufacturing costs $100 kWh. At the moment it is about $145. Attached article indicates profit on that is in the single digits. Lets be kind and say 10%. That is $10 profit for 1 kWh production.
Though some articles indicate the profit can be as low as 1.3% A 1GWh factory makes 1,000,000 kWh units. 1,000,000 x $10 = $10,000,000 at 10% profit. 1,000,000 x $1.30 = $1,300,000 at 1.3% profit.
