China's aggressive expansion of lead-acid battery recycling is structurally capping lead price upside, with secondary lead now accounting for more than 50% of the country's supply. Government policies promoting circular economy and tighter environmental standards for primary smelting have increased collection rates and processing capacity.
The rise in secondary supply is a key reason the global market remains in surplus despite steady demand growth. IMARC projects global refined lead demand reaching 5.7Mt by 2034 from 4.7Mt in 2025. Lead-acid remains dominant in automotive SLI, UPS backup, and stationary storage where lithium-ion has made limited inroads.
Recycling dynamics create a self-balancing price mechanism: higher LME prices accelerate scrap collection and recycling margins, increasing supply. ChAI's 1-year horizon is bearish. Conversely, prices below $1,800 would push marginal recycling capacity offline, providing a floor. This mechanism keeps lead range-bound.
