In case anyone is wondering what Prussian White is:
“Prussian white (PW) also referred to as Berlin White (BW) or Everett’s Salt (ES), is the totally reduced and sodiated form of the pigment known as Prussian Blue. The basic building blocks of Prussian White are sodium, iron, carbon, and nitrogen. It is the hexacyanoferrate based sodium rich iron analogue (Na2Fe[Fe(CN)6]) used as a positive electrode material in sodium-ion batteries.”

Bob Ross approves!
I’d be curious how upfront capital to set up LiFePO4 plant compares to the new sodium-ion offerings.
Sodium-ion definitely has some very appealing advantages over LiFePO4 from a transport/logistics (having the cells get moved around at 0 V is huge in terms of mitigating the liability headache of existing chemistries) and fixed installation perspective (know someone that’s already considering supplementing their solar storage LTO bank with sodium cells) but I’m struggling somewhat to see the advantages it offer for BEVs and if manufacturers will find it worth mass producing over other conflict mineral free chemistries.
It’ll be interesting to see of BYD details lifecycle cost for the different chemistries given they seem to be dumping capital into testing every proposed chemistry under the sun.
Excellent.
The rEVolution rolls on! 👍
Any timeline on production? If it’s just lab result, I’m not impressed, as a lot of companies can achieve that in small quantity lab samples already.
