Sodium-ion manufacturing in Spain is gaining momentum. A new partnership between Bihar Batteries and NX Technologies marks an important step for local battery production. Moreover, the agreement connects cell development with power electronics expertise for electric mobility. As a result, Spain strengthens its position in Europe’s growing Sodium-ion Battery market.
The announcement builds on wider industry progress. Sodium-ion battery technology has become more relevant as demand for energy storage keeps rising. At the same time, major companies are moving quickly. For example, CATL and Envision have launched dedicated energy storage products based on sodium-ion technology. In addition, CATL recently secured what many describe as the world’s largest sodium-ion battery order. That deal, signed with Chinese system integrator HyperStrong, totals 60 GWh. These figures show that sodium-ion batteries are moving from research to larger-scale commercial use.
Sodium-ion manufacturing in Spain gains support from a new partnership
Bihar Batteries stands out among Europe’s sodium-ion start-ups. The Spanish company has already produced sodium-ion cell prototypes. According to the company, those early cells delivered very promising results. Now, Bihar Batteries has taken another practical step. It has partnered with San Sebastián-based NX Technologies, a company that specializes in power electronics for electric mobility.
This partnership matters because successful battery manufacturing needs more than strong cell chemistry. It also needs integration, system design, and power management. Therefore, Bihar Batteries can pair its battery development work with NX Technologies’ expertise in electronics. Together, the companies can support applications in mobility and energy storage. In turn, that could help speed up commercial activity in Spain.
Why sodium-ion manufacturing in Spain is attracting attention
Several market factors support this shift. First, lithium iron phosphate, or LFP, cell prices have risen. Consequently, battery makers and buyers are exploring additional chemistries for energy storage and mobility. Sodium-ion technology has become an attractive option because it uses widely available sodium. This creates strong interest in regional manufacturing and supply chains.
Europe also sees a clear nearshoring opportunity. Instead of relying only on imported materials and products, companies can develop local production. Bihar Batteries has aligned itself with that goal. The company wants to build a local industry around sodium batteries. That strategy fits well with Europe’s broader focus on industrial resilience, energy security, and domestic clean technology manufacturing.
Another reason for interest is Bihar Batteries’ approach to raw materials. The company plans to source sodium from salt. In addition, it aims to use local raw materials such as wood to produce hard carbon. Hard carbon is widely recognized as one of the most promising anode materials for sodium-ion batteries. Because of this, Bihar’s model supports both local sourcing and battery innovation.
Sodium-ion manufacturing in Spain builds on research and prototype progress
Bihar Batteries did not reach this stage overnight. The company announced its first prototype late last year. It developed that prototype in collaboration with CIC energiGUNE, a well-known energy storage research center. CIC energiGUNE brings more than 13 years of experience in sodium-ion research. Thanks to that technical background, Bihar Batteries gained support from one of the field’s most established research institutions.
This research partnership gave Bihar a strong base for product development. Now, the collaboration with NX Technologies adds an industrial and commercial layer. In other words, Bihar is moving from prototype validation toward real-world integration. That progression is important for any battery company aiming to enter the market.
Sodium-ion manufacturing in Spain and Europe’s wider market trend
The Spanish partnership also reflects a much larger market trend. Across Europe, more sodium-ion battery companies are emerging. Investors, researchers, and manufacturers increasingly see value in building a regional sodium-ion ecosystem. Meanwhile, global leaders continue to validate the market. CATL’s 60 GWh order with HyperStrong stands out as a major sign of confidence. Large orders like that help show that sodium-ion batteries can support utility-scale and commercial projects.
For Spain, this momentum creates a timely opportunity. The country already has strong industrial capabilities, renewable energy growth, and active research centers. Therefore, sodium-ion manufacturing in Spain could become an important part of the wider European battery supply chain. Partnerships like the one between Bihar Batteries and NX Technologies help turn that potential into practical progress.
What the new partnership means for sodium-ion manufacturing in Spain
The collaboration sends a clear message. Spain’s sodium-ion sector is moving forward with a stronger local network. Bihar Batteries contributes cell innovation, local raw material ambition, and prototype progress. NX Technologies adds power electronics knowledge for electric mobility. Together, they create a more complete foundation for future products and commercial development.
Most importantly, the partnership supports the creation of a local sodium battery industry in Spain. It links research, manufacturing, and application expertise in one market. As sodium-ion adoption expands worldwide, Spain now has another example of how regional players can build capability early. For that reason, this new partnership represents a meaningful advance for sodium-ion manufacturing in Spain.
