What Basquevolt does

Basquevolt S.A.U. is a Spanish deep-technology company developing solid-state lithium-metal batteries for electric vehicles, heavy transport, renewable energy storage, and electronic devices, headquartered at the Parque Tecnológico de Álava in Vitoria-Gasteiz. The company was founded in June 2022 by a consortium of industrial and public-sector backers (Iberdrola, CIE Automotive, Enagás, EIT InnoEnergy, CIC energiGUNE, and the Basque Government) around a proprietary composite solid-state polymer electrolyte technology that originated from more than 10 years of research at CIC energiGUNE. Its first standardized commercial cell, the BQV400L, delivers 402 Wh/kg gravimetric energy density, 27 Ah capacity, NMC lithium-metal chemistry, 8.9C pulse power capability, HL3 safety certification, and is manufactured in Spain with 75% of components sourced in Europe. Basquevolt claims the polymer electrolyte is a drop-in technology compatible with existing gigafactory infrastructure, delivering approximately 30% lower capex per GWh and 30% less energy per kWh versus conventional lithium-ion production.

Basquevolt operates a B2B enterprise model with three revenue streams: sale of standardized cells and modules (the BQV400L launched May 2026, with sample deliveries to partners beginning in October 2024 and A-Sample manufacturing launched in June 2024), licensing of its proprietary electrolyte technology to cell manufacturers and gigafactories, and collaborative R&D funded by regional, national, and European grants (EIC Accelerator, PERTE VEC, Clean Aviation, ERDF). Pricing is not publicly disclosed and is negotiated per-project or per-volume with enterprise customers. The customer base is concentrated in a handful of large counterparties, notably Ampere (Renault Group) under a Joint Development Agreement, EDF and an unnamed automotive OEM conducting independent testing, BCARE for stationary applications, and consortium partners in aviation (Airbus, ATR, Daher via the LIME project) and maritime (LASAI Marine, Murueta Astilleros via the E-MAR project).

As of early 2026 the company is in pre-commercial industrialization, progressing from sample manufacturing toward TRL6 maturity and ultimately a 10 GWh target by 2027. Leadership was recently refreshed with Managing Director Pablo Fernández Santos and Chief Program Officer Nicolò Campagnol (ex-McKinsey Battery Insights) to lead commercialization. Cumulative funding includes a €10M seed round (June 2022), ~€10M from Ekarpen/Stellum/CDTI Innvierte (March 2025), ~€14.5M of EIC Accelerator blended funding (June 2025), and a 2026 round from Axon Partners Group with CDTI SICC Innvierte match-funding.

Revenue model

1. Electrolyte Materials & Technology Licensing: Basquevolt positions itself as a reference electrolyte supplier in Europe with strategic agreements with car and cell manufacturers. The company develops and produces its proprietary solid-state electrolyte which is sold or licensed to cell manufacturers and gigafactories. The technology is designed to be integrated into existing industrial manufacturing processes, facilitating scalability and reducing adoption barriers.
2. Battery Cells and Modules: Sale of standardized battery cells (e.g., BQV400L at 402 Wh/kg) and solid-state battery modules for stationary applications. The company manufactures sample cells (A-Sample plant operational since June 2024) and delivers cells to strategic partners for validation. First standardized cell product launched and available to customers in May 2026.
3. Collaborative R&D and Government Grants: Basquevolt participates in collaborative R&D projects funded by regional, national, and European programs (EIC Accelerator, PERTE VEC, Clean Aviation, ERDF-funded projects). While grants themselves are non-dilutive funding, they support R&D activities that contribute to product development and commercialization pathways.
