Ann: Altech - CERENERGY 50% Greenhouse Gases of Lithium Battery, page-4

In the EU Parliament research paper on sodium nickel chloride batteries I posted the link to several weeks ago:
An advantage of this technology is that iron impurities in the nickel, which are inevitable with the more abundant metal
coming from laterite ores, do not affect the viability of the battery. Laterite nickel mines are more
widespread and less strategic than sulphide-based mines.

Agree it would be nice to use greener nickel, but if becomes too expensive and/or more difficult to obtain in the future, it's good to know our battery can happily use the laterite based nickel.
