I agree with you on the lithium - it is far too abundant. It seems that most of the value in a catalytic converter is in the palladium and rhodium, though the platinum is worth something too. Catalytic converter chemistries vary a lot too, with some omitting platinum and some omitting palladium. Globally, the catalytic converter industry uses about 112 tons or platinum, 170 tons of palladium, and 21 tons of rhodium per year. And an individual catalytic converter uses 1-2g for a small car up to 12-15g in a big truck. (Elsewhere I've seen 3-7g as an average for a US catalytic converter.) https://www.thermofisher.com/content/dam/tfs/ATG/CAD/CAD%20Documents/Application%20&%20Technical%20Notes/Portable%20Analyzers%20for%20Material%20ID/Handheld%20XRF/AutoCatalyticConverter-AppNote.pdf https://www.thermofisher.com/content/dam/tfs/ATG/CAD/CAD%20D... So from what I can tell, an average catalytic converter contains about 5g of PGM's which works out at: 1.85g of platinum at $40/g = $74 2.80g of palladium at $95/g = $361 0.35g of rhodium at $900/g = $315 The Washington post reports that catalytic converter thefts are largely driven by the rhodium they contain (the price of which has gone up enormously because it is a byproduct of platinum mining and platinum itself is not currently worth mining.) https://www.washingtonpost.com/world/africa/catalytic-converter-theft-south-africa-rhodium/2021/03/03/dc288192-777d-11eb-9489-8f7dacd51e75_story.html https://www.washingtonpost.com/world/africa/catalytic-conver...
