Basquevolt has secured investment from Axon Partners Group and public funding from Spain’s CDTI to scale up production of its solid-state battery electrolyte. The technology claims roughly 50% higher energy density than conventional lithium-ion batteries and is designed to integrate into existing gigafactory manufacturing processes without major additional capital expenditure.
Basquevolt, a Spain-based solid-state battery technology company, has secured investment from Axon Partners Group alongside public funding from the Centre for the Development of Technology and Innovation (CDTI) through its Innvierte match funding scheme.
Axon Partners Group entered Basquevolt’s shareholding through its ClimateTech investment strategy, supported by Ventures EPM. The financial terms of the transaction were not disclosed.
The funding will support the scale-up of Basquevolt’s proprietary solid-state electrolyte production and the reinforcement of its manufacturing and validation capabilities as the company works toward reaching Technology Readiness Level 6 (TRL6).
“The entry of Axon Partners and the continuous support from CDTI represent a key milestone for Basquevolt at this stage of our development,” says Pablo Fernández Santos, managing director at Basquevolt. “This operation allows us to accelerate our industrial roadmap and move forward with greater confidence towards the pre-industrialization of our technology, supported by partners who share our long-term vision and strategic ambition.”
Basquevolt’s technology centers on advanced electrolytes designed to be integrated into existing cell gigafactory manufacturing processes, which the company says removes the need for additional capital investment in production infrastructure. The electrolyte is claimed to deliver roughly 50% higher energy density than current lithium-ion (Li-ion) batteries, which the company says would translate to equivalent gains in electric vehicle (EV) driving range without increasing battery size or weight.
The company is currently collaborating with three automotive original equipment manufacturers (OEMs) on the development and validation of its solid-state battery technology and says it will continue working with European automakers and advanced applications OEMs to align with market and industrial requirements.
“Basquevolt represents the type of deep-technology innovation Europe needs to accelerate the energy transition,” says Alvaro Pascual, senior associate at Axon Partners Group. “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.”
Basquevolt has previously received funding from regional, national, and European programs, including the European Innovation Council (EIC) Accelerator, as well as sector-specific projects in aviation, stationary energy storage, and other advanced applications.
