BASQUEVOLT, a European technology company specialised in next-generation solid-state battery technology, today announced the entry of Axon Partners Group, through its ClimateTech investment strategy supported by Ventures EPM, into its shareholding structure as a investor, together with complementary public funding through a CDTI (Centre for the Development of Technology and Innovation) with its SICC Innvierte match‑funding scheme.

This transaction will enable BASQUEVOLT to further advance its path toward industrialisation, strengthening its position within the European advanced battery ecosystem and supporting the development of a competitive and resilient battery value chain in Europe.

BASQUEVOLT’s technology focuses on the development of advanced electrolytes for next‑generation batteries, designed to significantly enhance energy density, fast charging, safety and overall battery performance. The company’s approach is based on solutions that can be integrated into existing industrial manufacturing processes, facilitating scalability, reducing costs and accelerating adoption by industrial cell makers while lowering barriers to large‑scale deployment.

The resources secured through the entry of Axon Partners Group and the support of CDTI-Innvierte will enable BASQUEVOLT to advance its industrial roadmap, including the scale-up of electrolyte production and the reinforcement of its manufacturing and validation capabilities. Axon brings strategic value through its experience investing in technology-driven companies, particularly in deep tech energy transition technologies, as well as its strong track record in supporting the industrial scaling of innovative ventures.

Axon´s participation further reinforces BASQUEVOLT’s strong institutional, technological and industrial ecosystem, supporting the company´s long‑term growth strategy as it advances towards the expansion of its cell manufacturing capacity and the scale-up of electrolyte production required to reach TRL6.

In parallel, BASQUEVOLT will continue to work closely with European Automotive manufacturers and advanced applications OEMs on the development and validation of the solid-state battery technology - building on existing collaborations with three automotive OEMs – to ensure strong alignment with market and industrial requirements as it moves towards large‑scale industrialisation.

 “Basquevolt represents the type of deep-technology innovation Europe needs to accelerate the energy transition. Their solid-state electrolyte technology combines breakthrough performance with industrial scalability, addressing some of the most critical challenges in next-generation energy storage. At Axon, we are excited to support the team in advancing from technological validation towards large-scale industrial deployment.” said Alvaro Pascual, senior associate at Axon.

“The entry of Axon Partners and the continuous support from CDTI represent a key milestone for BASQUEVOLT at this stage of our development. This operation allows us to accelerate our industrial roadmap and move forward with greater confidence towards the pre-industrialisation of our technology, supported by partners who share our long‑term vision and strategic ambition,” said Pablo Fernández Santos, BASQUEVOLT Managing Director.

Breakthrough electrolyte unlocks 50% higher driving range

BASQUEVOLT’s solid-state electrolyte delivers roughly 50% higher energy density than today’s Li-ion batteries, enabling electric vehicles to achieve similar gains in driving range without increasing battery size or weight. The technology also addresses critical safety challenges and is fully compatible with existing cell Gigafactories, requiring no major additional investment in the manufacturing process. Together, these advances position BASQUEVOLT’s solid-state battery technology as a high-performance, safer and industrially scalable solution for next‑generation energy storage applications across the automotive, aviation and other advanced applications industrial sectors.

Strategic public and private funding, together with OEM customers, driving BASQUEVOLT’s progress

BASQUEVOLT has secured significant support over the years through a combination of competitive public and private funding. This includes grants from regional, national and European programmes - such as the EIC (European Innovation Council) Accelerator - as well as sector‑specific projects spanning aviation, stationary energy storage and other advanced applications.

Together, this mix of public funding, private investment and industrial partnerships has been instrumental in advancing BASQUEVOLT’s R&D activities, scaling laboratory breakthroughs toward industrial readiness, and accelerating the development of key materials such as its proprietary solid‑state electrolyte.
