Job Description

Job Title: R&D Research Scientist - Advanced Electrolyte Synthesis

Location:

Saint-Germain-de-Grantham, Quebec, Canada

Company: Annexair Energy Division

Job Summary

We are seeking a motivated R&D scientist with expertise in non-aqueous electrolyte synthesis, purification, and advanced characterization under strict inert-atmosphere conditions to join our growing research team. This position offers the opportunity to work on an innovative project focused on designing high-performance electrolyte systems for aluminum battery chemistry. This role requires hands-on laboratory expertise in glovebox synthesis, rigorous moisture/oxygen control, and specialized purification methods such as liquid-liquid extraction to remove reactive contaminants. The position involves close collaboration with multidisciplinary teams to integrate electrolyte innovations with other cell components.

Key Responsabilities

Design, synthesize, and optimize non-aqueous battery electrolytes, including tailored additives to enhance stability and performance. Develop and optimize laboratory-scale synthesis methods and protocols to produce high-purity liquid and solid precursors, with rigorous control over air/moisture sensitivity, as well as Karl Fischer titration. Develop and execute drying and purification workflows, including vacuum drying, activated molecular sieves for water removal, solid-phase purification using basic ion-exchange or adsorption media, and acid scavenging strategies. Liquid-liquid extraction methods for selectively removing chloride or acidic contaminants. o Perform speciation and compositional analyses via NMR, FTIR, Raman, XPS, UV-Vis, and other advanced spectroscopy. Interpret analytical and characterization data, correlate findings with electrochemical performance, and communicate results clearly through reports and presentations. Facilitate knowledge transfer, including fundamental process insights and recommendations for equipment modifications. Ensure compliance with laboratory safety procedures and best practices for handling corrosive, hygroscopic, air-sensitive, and hazardous chemicals.

Required Profile

Ph.D. in Chemistry, Chemical Engineering, Materials Science, or related discipline, with a strong focus on non-aqueous chemistry.

Other Qualifications & Skills

Proven experience with air-sensitive synthesis and glovebox techniques. Strong expertise in purification methods, particularly liquid-liquid extraction and advanced drying procedures. Experience in advanced analytical and characterization techniques, including NMR, XPS, XRD, Raman, FTIR, etc. Experience with Karl Fischer titration and rigorous oxygen/moisture monitoring protocols. Familiarity with Lewis acid systems is an asset. Strong problem-solving skills and an innovative mindset for designing robust synthesis and purification strategies. Ability to work independently with minimal supervision while collaborating effectively in a multidisciplinary R&D environment. Excellent documentation, communication, and teamwork skills. Prior experience in battery electrolyte development or electrochemical systems (asset). * Experience with electrochemical testing methods and correlating chemical properties with cell performance (asset).
