Purity requirements.This news seems to indicate that they are meeting the purity requirement that the tier 1 supplier was requiring. That is probably the only way Larry would go forward this way. The news also indicates something else. AMY will sell the intellectual property rights and also a construction design for using the process. This design may be usable by more than one battery maker. When the government agencies demand a through level of recycling for all Critical minerals, they will not have a choice. Amy does not want to be a plant operater, there is better profits in selling the rights.We will also see the returns quicker that way.
