this work does nothing to address this, and they also include yttrium, because they focus on solid electrolytes for some reason (probably because chemical space is smaller)
Comment on AI comes up with battery design that uses 70 per cent less lithium

LFP batteries are both nickel and cobalt free, and are being used in production cars right now (e.g. Tesla model 3/Y standard range options). That technology has long arrived.

Yes, also Lithium Manganese Spinel cells which have been around since 1996 and also don’t contain any nickel and cobalt. This is good but many vehicles and devices still use NMC and NCA due to the better specific energy density which is where LFP is limited (but can output more power and is much safer). Tesla compromises on the battery, where if they could reduce the need for expensive metals while maintaining specific energy it would be pretty newsworthy.
