Electrolyte Cell Component Engineer M/F

We are currently looking for our future Electrolyte Cell Component Engineer to join our Product Development department based in our Innovation Center in Grenoble, France. As such, you are responsible for the design, development, and optimization of electrolyte systems for advanced battery cells. This role focuses on tailoring electrolyte formulations to improve electrochemical performance, lifetime, cost, safety, and manufacturability for a range of electrode chemistries in Verkor’s innovation development roadmap. This role spans early research through to successful validation of cell performance and manufacturability at pilot plant scale (MWh).

Main responsibilities

Design and optimize electrolyte formulations, including solvents, lithium salts, and functional additives Develop electrolytes targeting improved electrochemical stability, lifetime, and safety with consideration of cost Tailor electrolytes for specific chemistries in Verkor’s roadmap by optimizing SEI and CEI formation through electrolyte composition and additive selection Test and evaluate electrolyte candidates against performance, safety, and manufacturability KPIs in coin and pouch cells. Define and execute electrochemical testing and analyses (cycle life, rate capability, EIS, calendar life, CV, dQ/dV). Perform diagnostic studies to understand degradation mechanisms related to electrolyte chemistry. Support post-mortem analysis to correlate electrolyte chemistry with failure modes as part of an iterative development improvement cycle. Participate in root-cause failure analyses to understand cell failures and suggest improvement actions. Interface with suppliers for materials qualification and specification definition. Provide technical input to project milestones, reviews, and cross-disciplinary decisions Contribute to patents, trade secrets, and internal know-how related to electrolyte technologies Suggest new strategies for Verkor’s cell technology roadmap, including adapting literature to real-world industrial conditions.
