Sodium-ion: The Three Big Promises of Sodium-Ion Batteries
Sodium-ion batteries offer a promising alternative to lithium-ion, with advantages in mineral abundance, system compatibility, and safety. They provide a cost-effective, scalable solution with lower material costs and reduced supply chain risks. Despite lower energy density, sodium-ion cells benefit from existing manufacturing infrastructure. Safety benefits include reduced fire risks and enhanced thermal stability. Key strategies for success include improving energy densities, competing on total cost of ownership, and targeting niche performance areas such as low temperature and high-power applications.
