The challenge

Sodium batteries are a promising alternative to lithium-ion batteries in some niche markets such as the stationary market. On the other hand, battery safety has become one of the great challenges of the future. In this respect, solid-state batteries will substantially increase safety performance. The objective of this project is to generate a family of solid state sodium batteries that have technical performance very close to current lithium-ion batteries so that they can be a possible substitute for this technology in some market niches.

The solution

A configuration of cathode materials, solid electrolyte and metal anode has been developed that provides similar performance to Lithium-iron-phosphate (LiFePO4). Likewise, the improvements with respect to the safety of this new technology have been studied. The manufacturing process of this pouch cell configuration has been developed and complemented with a technical-economic feasibility analysis.


This new solid-state sodium battery configuration will enable the industrialization of cells that could cost 20% less than lithium-ion cells of similar performance and be safer. Since it is based on sodium, this price will not be subject to market fluctuations. As a result of this research a new patent has been generated.
