2023 Global Lithium Battery Supply Chain Capacity Distribution: A Multi-Polar Landscape Under China's Dominance

Overview of Global Lithium Battery Supply Chain Landscape

The lithium battery supply chain covers multiple segments from upstream materials to cell manufacturing. In 2023, global capacity is highly concentrated in East Asia, while Europe and the US are accelerating localization. This infographic compares capacity share across five segments (cathode, anode, electrolyte, separator, cell) for five major economies, based on public data and industry estimates.

Key Findings

• China: Dominates all five segments, especially in anode (85%) and separator (80%). High but contested positions in cathode and cell.
• South Korea: Strong presence in cathode and electrolyte (~10-15%), driven by LG Chem, Samsung SDI.
• Japan: Traditional chemical power, retains technical edge in separator (~8%) and anode (~5%).
• Europe: Catching up in cathode and cell, supported by local projects like Northvolt and ACC (combined ~10%).
• US: Expanding rapidly in cathode (~5%) and cell (~8%) via IRA, but upstream materials remain import-dependent.

Data Interpretation

Stacked areas represent relative shares of countries/regions within each segment. Note that capacity does not equal production, and is influenced by technology pathways and resource endowments. Over the next five years, diversification and overseas capacity deployment will be key strategies for Chinese enterprises.
