Abundant. Scalable. Sodium-Ion.
Sodium-ion technology uses widely available sodium compounds to store energy safely and efficiently. By reducing reliance on lithium and other constrained materials, it offers a promising pathway for cleaner, more resilient energy storage.
The Eco-Friendly Advantage of Sodium-Ion
Sodium-ion batteries use widely available materials. By reducing dependence on constrained minerals such as lithium, cobalt, nickel and copper, they help create a cleaner, more flexible, and more resilient battery supply chain.
- Built from abundant sodium resources (seawater)
- Potential to reduce critical mineral reliance
- Supports a more resilient battery supply chain
Why Lithium Alternatives Matter
Rising demand for lithium-ion batteries is increasing pressure on mining regions, water resources, and global supply chains. Sodium-ion technology offers a practical way to diversify the future of energy storage.
- Lithium extraction affect water-stressed regions
- Threat to biodiversity and local communities
- Supply chains are geographically concentrated
