Global demand for advanced battery technologies is surging due to the energy transition, fueled by the rise of data centers and artificial intelligence. Lithium-ion batteries, which are crucial for energy security, saw their market reach over $150 billion in 2025 with a year-on-year growth of over 20%. However, concerns are rising about global dependence on a few lithium suppliers, predominantly China, which controls 72% of the global lithium-ion market and produces over 80% of battery cells.
China’s steady expansion in lithium supplies and manufacturing capabilities has positioned companies like CATL, BYD, and Gotion High-Tech as leaders in the field. This has made it challenging for other nations to compete, as Chinese production remains significantly cheaper. Meeting global energy security goals while mitigating China’s market dominance poses political challenges.
Efforts are underway to innovate beyond lithium, with sodium-ion batteries emerging as a promising alternative due to their abundance and lower environmental impact. Yet, China is a dominant player in this market as well. Addressing these supply chain imbalances will require significant international cooperation and investment. Despite these hurdles, the quest for diverse and sustainable battery technologies continues in the face of increasing global demands.
