Revolutionizing energy storage: The future of sodium-ion batteries

As the demand for electric vehicles and large-scale energy storage continues to grow, the limitations of lithium-ion batteries are becoming increasingly apparent, particularly concerning resource shortages. This is where sodium-ion batteries emerge as a crucial alternative. Sodium-ion batteries utilize raw materials that are more abundant and less expensive than those used in lithium-ion batteries. This abundance not only helps to stabilize supply chains but also reduces costs, making sodium-ion technology an appealing option for various applications. The potential for sodium-ion batteries to alleviate the pressures of lithium resource scarcity is significant, especially as the global energy transition relies heavily on effective energy storage solutions.

Sodium-ion batteries are emerging as a cost-effective and sustainable alternative, poised to challenge the dominance of lithium batteries in the stationary energy storage sector. The goal of the SPRINT project is to optimize and demonstrate two types of sustainable, techno-economically viable, and safe quasi-solid-state sodium-ion batteries that better align with the needs of stationary energy storage applications.

To achieve this, SPRINT will utilize abundant, non-toxic, and safe materials sourced from competitive EU supply chains. Key innovations include:

• Optimized NFP cathode materials 
• Hard-carbon materials derived from a validated supply chain of forest residues in Northern Europe
• Quasi-solid-state polymer and polymer composite electrolytes that employ a solvent-free synthesis, marking a substantial advancement over traditional flammable liquid electrolytes
