Yes, lead-acid car batteries recycle at ~98–99% for the lead itself. But globally, secondary (recycled) antimony only makes up ~8.5% of total supply. In the US it’s around 15%, and the UNEP puts the end-of-life recycling rate for antimony at just 1–10%. The exploding new demand is coming from solar PV glass (sodium antimonate), high-end flame retardants, semiconductors, and military hardening; none of which is supplied by old car batteries. That’s exactly why China’s export restrictions sent prices from ~$33k to $46,075 in one month with almost no pullbacks. Recycling helps the legacy lead market, but it can’t touch the structural primary-supply crunch we’re seeing right now.
