Technically, no. Not "battery grade".

It needs to go through a converter to be "upgraded" to Cabonate or Hydroxide, which is why our offtake partner is building a conversion facility.

However, the quality of the Spod coming from A40 is apparently world class, making the converters lives easier.

So no, it is not "battery grade" in itself - but it is easier to use A40 product to upgrade to battery grade, than to use some others.
Meaning the profit in the process is potentially higher, which can be shared with us.
