CATL: Mining, Not Smelting, Is the Real Bottleneck in the Battery Supply Chain
Alina Collins
CATL VP Jiang Li declared mining is the real bottleneck in the battery supply chain — directly contradicting Ford and other customers who see refining as the bigger constraint — as the company sets up a new mining division and positions sodium-ion batteries as a lithium-price hedge.
Why does CATL say "processing isn't the bottleneck — mining is"?
VP Jiang Li's logic is straightforward: China already dominates smelting and refining, but raw ore still depends heavily on imports. That is where the chain actually gets stuck.
This means → CATL is shifting its strategic center of gravity upward — from "who processes the metal" to "who controls the mine" — the opposite direction from Ford's diagnosis.
Jiang acknowledged that technology can ease metal shortages over time, but the market sometimes moves faster than innovation allows — so mining comes first.
What is CATL actually doing about it?
The company plans to establish a new mining division and has hired Chen Jinghe, founder of China's largest metal mining group, as an adviser.
Its mining portfolio already spans lithium, phosphate, and cobalt projects both inside and outside China.
But real-world challenges are already visible: CATL's large lithium mine in Jiangxi province has suffered ongoing production disruptions since August — one of the factors behind recent lithium-price volatility.
What role do sodium-ion batteries play in this strategy?
Jiang positions sodium-ion batteries as a hedging tool against lithium prices: if lithium gets expensive, CATL ramps up sodium-ion production instead.
In plain terms = sodium is one of the most abundant elements on Earth. Building batteries from it removes the dependence on lithium supply — effectively an insurance policy on raw materials.
This reflects CATL's risk-management logic — not betting that any single material stays cheap, but ensuring it has viable options under different price scenarios.
What will determine whether this strategy works?
The validation point is singular: can mining supply keep pace with demand expansion?
China controls refining, but ore still comes from abroad. This means → geopolitical and operational risks at the mining stage will transmit directly through the entire battery chain.
The Jiangxi lithium-mine disruptions already offer a real-world signal: owning a mine and running it reliably are two different things — the latter is the real test.
