Sodium-ion batteries are increasingly being adopted as a promising alternative to lithium-ion technology. Made from abundant materials like common salt, they offer a cheaper and safer solution for energy storage. Major players such as CATL and BYD are leading the charge, with CATL having introduced the first generation of such batteries back in 2021 and BYD constructing a large-scale production facility in China. These batteries are already being tested in various applications, including compact vehicles and grid storage, which could help stabilize renewable energy systems. The widespread adoption of sodium-ion batteries could reduce dependence on lithium, whose supply is more limited and subject to price volatility.
