en.Wedoany.com Reported - CIC energiGUNE is accelerating the development, validation, and scaling of sodium-ion battery technology in the Basque Country. As an alternative to lithium, sodium-ion batteries are gaining increasing international attention due to their potential to reduce dependence on critical raw materials and build a more sustainable supply chain.

Jon Ajuria leads CIC energiGUNE's research on sodium-ion batteries as a lithium alternative.

The Basque center collaborates with startups, manufacturers, and industrial companies to mature sodium-ion battery technology, facilitating its transition from laboratory environments to real-world applications.

As global battery demand continues to grow and pressure on resources like lithium intensifies, the industry is turning its attention to new chemical systems such as sodium-ion. This technology relies on materials that are more abundant and widely distributed globally, making it a strategic choice for diversifying energy supply.

The center states that lithium will remain a key material in several sectors, but sodium-ion batteries offer clear advantages in areas where cost, safety, sustainability, and scalability are decisive, such as stationary energy storage or specific industrial applications.

The main challenge today is not only to improve battery performance but also to demonstrate its feasibility in industrial-scale manufacturing. Many technologies that show promise in the lab often encounter difficulties under real-world production conditions.

CIC energiGUNE reduces technical risks through activities such as validation, degradation analysis, prototyping, and techno-economic assessment, aiming to accelerate its commercialization. The center also develops comprehensive capabilities ranging from material modeling and discovery to electrochemical validation and industrial scalability, enabling it to collaborate with various players in the ecosystem, including startups, battery manufacturers, and technology integrators.

The goal is to shorten the distance between scientific research and industrial application, making sodium-ion technology competitive and manufacturable. Advancing such technologies is a necessary step toward building a more resilient and sustainable energy system. In this context, sodium-ion stands out as one of the most promising alternatives in the next generation of energy storage.
