Top Sodium Ion Battery Manufacturers

What are sodium-ion batteries, and why are they important in energy storage?

Sodium-ion batteries are rechargeable batteries that use sodium ions (Na+) instead of lithium ions to store and release energy. As the demand for sustainable and cost-effective energy solutions grows, sodium-ion technology is gaining traction due to its affordability, safety, and environmental benefits.

Unlike lithium, sodium is abundant and widely distributed, reducing geopolitical risks and supply chain bottlenecks. Sodium-ion batteries also offer excellent thermal stability, making them ideal for grid storage, electric vehicles (EVs), and industrial applications. With advancements in energy density and cycle life, sodium-ion batteries are emerging as a viable alternative to lithium-ion batteries.
