Solving Spatial Mismatches in China's EV Battery Recycling Could Save Six Billion Tons of CO2

What Happened

A new study from Fudan University suggests that China is missing significant climate and economic opportunities due to where retired electric vehicle (EV) batteries are located versus where they are needed. Currently, most batteries are processed through low-value metallurgical recycling, which ignores their potential for energy storage or material regeneration.

Researchers found that a severe mismatch exists between provinces: batteries accumulate in developed eastern regions, while demand for storage and recycling is concentrated in the west and manufacturing hubs. This logistical gap locks up billions of tons in potential carbon emission reductions.

The study highlights that building efficient interprovincial transport networks could unlock up to four thousand billion yuan in savings. Researchers emphasize that transport costs are negligible compared to the massive gains in efficiency and environmental impact that could be realized through better planning.

The Core Points

Six billion tons of CO2 reduction potential is currently stranded due to geographic mismatches.
Shifting to direct recycling and energy storage offers 3 to 5 times more cost savings than traditional methods.
Transporting batteries across provinces adds only minimal costs compared to the massive climate benefits.
The study recommends phasing out basic metallurgical recycling after 2030 in favor of high-value pathways.
The findings provide a scalable model for other nations managing rapid EV fleet electrification.

Context in 60 Seconds

The global transition to electric mobility is creating a massive wave of end-of-life batteries that requires a shift from simple waste management to resource recovery. As EV fleets expand, the ability to repurpose batteries for grid storage or direct material reuse is becoming essential for both corporate sustainability and national energy security.

This research provides a template for other major markets like the U.S. and Europe, which face similar geographic imbalances. It underscores that the primary obstacle to a circular battery economy is not technology, but rather the logistical and regulatory framework required to move materials efficiently between regions.

Bottom Line

Coordinated national transport networks and a shift toward high-value battery reuse are essential to capturing billions in economic value and major carbon savings by 2050.
