Despite decades of evidence on the toxic effects of lead battery recycling, companies opted not to act and blocked efforts to clean up the industry.

Misleading headline making it sounds like all battery recycling poisons people. Half assed battery recycling is half assed.

Also sodium ion or some other lead-free formulation will likely replace lead acid 12v batteries over the next few years.

The advantage lead acid has for ICE is that it can dump a lot of current all at once. The C output rate on sodium ion isn't that high, IIRC.

There have been lithium batteries used for the purpose. The original Miata used one because standard lead acid cells caused corrosion issues in the chassis. But lithium has its own supply chain issues.

Ultimately, this goes away because ICE cars go away.

That's where capacitor-based jump-starters come in.

Well, there is still the temperature constraints of Lipo and LiFePo batteries (the latter being much better at cold and hot charging).

But the point is that lithium batteries operate under a pretty big compromise of needing heating and cooling when temps are too cold and too hot, respectively. That is where lead acid has a pretty significant advantage.

Edit: I had a 1991 miata, and I don't recall having a lithium battery. It was rear-mounted, though.

Me wondering how ICE is tracking people through their car batteries when I first read this 🤔
