| Yibin / Yichun | Sichuan / Jiangxi | Material hubs | Inland cathode/lithium material |
The clusters roll up into a clear provincial picture: Guangdong holds roughly 25% of China's battery factories, Jiangsu about 18%, and Zhejiang about 15% — together a majority of the country's battery production. These are approximate shares that vary by source and definition, but the concentration in the eastern coastal provinces is consistent.
Lead-acid has its own geography. Changxing (Zhejiang) is the lead-acid heartland — home to Tianneng and Chaowei, two of China's largest lead-acid makers — alongside the automotive lead-acid base in Baoding (Hebei, Fengfan) and Xiangyang (Hubei, Camel). The lead-acid map is more dispersed than lithium, reflecting a mature, regionalised industry.
Clusters exist because battery-making pulls in a dense supply chain — cathode and anode materials, electrolytes, separators, equipment and labour — and those suppliers cluster around the anchor maker. The result is an agglomeration advantage: a new cell plant in Ningde or Changzhou plugs into an existing chain, which is a large part of why China's ~80% global capacity share is structurally hard to replicate elsewhere.
Where I stand: The most useful map of China's battery industry is not a list of companies but a list of clusters — because the cluster, not the company, is what makes the ~80% capacity share self-reinforcing and hard to relocate.
The reasoning: Batteries are made where the supply chain already is. The Ningde–Shenzhen–Changzhou triangle concentrates the materials, equipment and talent, so each new plant strengthens the cluster. Anyone analysing China's battery supply chain should start with the geography, because the geography is the moat.
