CATL Bets Big on Sodium Batteries as Lithium Volatility Persists

CATL, the world's largest battery manufacturer, is doubling down on sodium-ion technology as lithium price swings continue to challenge the energy storage industry. The Chinese giant, officially known as Contemporary Amperex Technology Co. Ltd., has been building its energy storage portfolio for years, but the shift has accelerated sharply with the artificial intelligence boom driving demand for grid-scale batteries. Five years ago, only 2% of CATL's sales came from battery storage; today, that figure has jumped to a quarter of the company's revenue.

For energy commodity traders, CATL's pivot carries significant implications. Sodium-ion batteries use abundant and geographically widespread raw materials—sodium, iron, and manganese—compared to lithium, which is concentrated in a handful of countries and subject to geopolitical and supply-chain risks. A successful scale-up of sodium-ion technology could dampen long-term lithium demand growth, potentially easing price pressures on lithium carbonate and related commodities. Traders tracking battery metals can monitor real-time price moves on NowPrice's live fuel dashboard, which covers lithium, cobalt, and other critical minerals alongside traditional energy benchmarks.

The near-term outlook for sodium-ion remains uncertain. While CATL and other manufacturers have announced production targets, commercial deployment at scale is still years away. Key milestones to watch include CATL's next earnings report for updates on storage revenue share, as well as any new sodium-ion supply agreements with utility and data-center operators. The pace of AI-related energy demand growth will also be a critical driver, as hyperscale data centers increasingly turn to battery storage for backup and peak-shaving.
