Changzhou Jintan Battery Hub
常州金坛动力电池产业
Jintan represents China's most remarkable county-level industrial transformation — from Changzhou's "pot bottom pond" (锅底塘) to a global power battery hub in under a decade. The unique "twin star" structure — CALB (#3 China, #4 world) and SVOLT (Top 10 globally), both headquartered in Jintan — creates competitive dynamics that drive innovation. The 97% industry chain completeness within a 30km radius (cathode/anode materials, separator, electrolyte, cell, module, BMS, pack, recycling) is unmatched globally. The "Jintan Model" of government-led restructuring (CALB's 2018 turnaround from AVIC Lithium, with Jintan state assets participating) is a case study in government-industry collaboration. CALB's OS battery technology and SVOLT's cobalt-free and all-solid-state prototypes demonstrate innovation. However, Jintan lacks a strong vehicle OEM ("strong battery, weak vehicle"), creating structural imbalance. The 2024-2025 battery industry overcapacity and price competition affect margins, and geographic competition with neighboring Liyang (CATL) is intense.
