> LFP is reported at ~$80/kwh for large Chinese buyers. Are those figures accurate?

Yes, automotive buyers were having it for less than $100 per kWh for at least 5 years now. Still not sure for which density range these prices are. 190wh/kg LFP cells are now available in retail, and 200wh/kg been around for at least 2 years for automotive, and been used in EV busses from a few manufacturers.

It wouldn't be a stretch to say that biggest, and longest term contracts can get it to $60 per kWh.

Lowest end, storage class LFPs must also be quite cheap in lower volumes, and haven't looked at them for a long time.
