Spain has heard that some slavery is used by Subcontractor A at Mine B in Zimbabwe, which sells to Distributor C which also works with Mines D, E and F and sells bulk lithium on the international lithium markets where distributors G and H also sell, and where Battery Factory I buys some of their lithium but they also buy from J and K, and they manufacture cells under contract for battery brand L which sells them to home solar battery assembler M who also buy cells from brands N and O and actually only sell things ex-works in China, and Reseller P imports them into the EU.

Subcontractor A says the reports of slavery were wrong, that was actually perfectly legal prison labour. Mine B says actually they no longer work with Subcontractor A, and a local government inspector has certified them as slavery-free. Between C and O all the bulk materials get commingled, records occasionally get a bit mixed up, and precise sourcing details are commercially confidential. The battery reaches the shores of the EU with no known links to slavery.
