AFAIK Tesla produces the biggest number of batteries, and so their batteries should take most benefit from the production scale. Yet a powerwall, which I believe is made from disapproved car batteries, cost $7000 for 13.5kWh. An I-miev has a 16kWh battery, and so should cost $8300 when it was made from disapproved Tesla batteries. OK, that's less than $10k, but not much.
On the other hand, Sono motors doesn't build their own batteries, but buys them from a specialized manufacturer. They expect a 35kWh battery for their Sono Sion will cost €9500 ($10700) in 2022. So at this rate a new I-miev battery would cost $5000. That's better. But it's not 2022 yet.
