Basquevolt has secured new investment from Axon Partners Group as it advances the industrialisation of its solid-state battery technology.
The investment, made through Axon’s ClimateTech strategy and supported by Ventures EPM, is complemented by public funding from CDTI (Spain’s national innovation agency) under its Innvierte co-investment programme. Financial terms were not disclosed.
Basquevolt is developing solid-state electrolytes designed to improve energy density, charging performance and safety compared with conventional lithium-ion batteries. The company said its technology is intended to be compatible with existing battery manufacturing infrastructure, enabling integration into current gigafactory production lines without significant additional capital investment.
Basquevolt’s transition towards industrial scale-up
The new funding will support Basquevolt’s transition towards industrial scale-up, including expansion of electrolyte production capacity and further development of manufacturing and validation capabilities. The company is targeting progression towards technology readiness level 6 (TRL6), a key milestone for pre-industrial deployment.
Basquevolt is also continuing to work with automotive manufacturers and other OEMs on validation of its technology, building on existing collaborations with multiple partners.
Solid-state batteries are widely viewed as a potential next step in battery development, offering higher energy density and improved safety through the use of solid electrolytes rather than liquid systems. Basquevolt said its technology could enable around 50% higher energy density, which could translate into increased vehicle range without increasing battery size or weight.
The company has previously secured a mix of public and private funding, including support from European and national programmes such as the European Innovation Council. These funds have been used to advance materials development and scale laboratory concepts towards industrial readiness.
“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.
Axon Partners said the investment aligns with its focus on energy transition and deep technology sectors, including energy storage and grid flexibility.
“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.
