RS2E

What RS2E does

RS2E (Réseau sur le Stockage Électrochimique de l'Énergie) is a French public research network operating as a CNRS Laboratory of Excellence (LabEx STORE-EX, registered as CNRS FR3459) and headquartered at 15 Rue Baudelocque, Amiens. The network connects 17 CNRS-University laboratories across France to accelerate fundamental research and industrialization of new battery and supercapacitor technologies, spanning lithium-ion, solid-state, sodium-ion, zinc-based, and sulfur chemistries. It employs 140 full-time researchers and funds 110+ PhDs and postdocs, producing 160+ peer-reviewed publications annually and managing 32 active patent families. Core research assets include optical fiber Bragg grating (FBG) sensors for in-situ battery monitoring, anionic redox chemistry for high-energy-density cathodes, MXene pseudocapacitor materials, and Zn/MnO2 aqueous battery technology.

RS2E operates a community-led go-to-market model rather than a commercial sales motion. Its value proposition is delivered through research services (analytical platforms, a pre-prototyping unit, intellectual property management) and education programs (the i-MESC European Master's, ENSCBP specialization module, and Batteries Professional Bachelor). Industrial partners — including Renault, EDF, Saft (TotalEnergies), Arkema, Umicore, A2MAC1, and emerging startups such as Tiamat and Kemiwatt — gain access to cutting-edge research, talent recruitment, and technology transfer pathways. The network is led by Director Jean-Marie Tarascon (CNRS Gold Medal 2022, Balzan Prize 2020) and Deputy Director Patrice Simon (Académie des sciences member).

The business model is non-commercial: RS2E does not sell products or services and generates no commercial revenue. Operating budget is sourced from French government programs (Investissements d'avenir, France 2030), the Ministry of Higher Education, Research and Innovation, CNRS institutional funding, and European Horizon 2020/Europe research grants. Customer segments are therefore two-fold: an academic research community accessing advanced platforms and collaboration, and industrial members seeking research co-development and technology maturation. Customer pricing is structured via direct partnership agreements rather than published commercial pricing.
