This implies a bulk cost of about $57/kWh which is slightly cheaper than present day LFP (the primary competitor for grid-scale battery storage). IMO, it needs to be no more expensive than LFP, because LFP cells can be spec'd for ~8 years and it's hard to get people to invest on timescales longer than ~10 years.
