Principal / Lead Scientist – Cathode Development (Lithium-Sulfur Batteries)

We are partnering with a pioneering battery technology company developing next-generation

lithium-sulfur battery systems , with a strong focus on high-performance cathode architectures and pouch cell development. The organization is focused on translating advanced chemistry into scalable, industrially relevant battery solutions.

This is a unique opportunity for a

Principal/Lead Scientist

to play a central technical role in shaping cathode development strategy, influencing key cell architecture decisions, and advancing lithium-sulfur technology from experimental validation through industrial scale-up.

In this role, you will contribute hands-on to

cathode materials development and pouch cell fabrication , electrochemical performance evaluation, and materials characterization, while working closely with

cross-functional technical and engineering teams. Your work will directly support the experimental validation, scale-up readiness, and long-term reliability of the company’s core lithium-sulfur battery technology.

Why Join? High Technical Impact:

Contribute directly to the advancement of next-generation lithium-sulfur battery technology. Scientific Ownership:

Take ownership of cathode concepts and their translation into full pouch cell performance. Scale-Up Focus:

Work closely with cross-functional teams to address real-world challenges in cell assembly, durability, and consistency.

Key Responsibilities: Design, develop, and optimize cathode materials and architectures for lithium-sulfur battery systems. Lead and support pouch cell fabrication, assembly, and performance evaluation activities. Conduct and interpret advanced electrochemical testing, including EIS, CV, rate capability, and cycling performance. Investigate degradation mechanisms and failure modes using SEM, XPS, and post-mortem analysis. Collaborate with internal teams on electrode processing steps such as coating, drying, calendering, and cell assembly. Support continuous improvement of cathode formulation, sulfur utilization, and overall cell performance. Contribute to technical documentation, patent filings, and scientific publications.

What We’re Looking For: PhD in Materials Science, Chemistry, Electrochemistry, Chemical Engineering, or a closely related field. Minimum 5 years of hands-on experience specifically in lithium-sulfur battery R&D, with clear depth in cathode development and pouch cell systems. Strong background in electrochemical characterization and materials analysis (e.g., EIS, CV, SEM, XPS). Ability to work independently on complex experimental challenges while collaborating effectively in multidisciplinary technical teams. Proven contributions to patents, publications, or proprietary technology development within battery-related research.

What’s on Offer: Compensation aligned with senior technical expertise. Opportunity to work on core lithium-sulfur battery technology with direct industrial relevance. Collaborative, science-driven environment with a strong focus on innovation and technical excellence. Long-term growth opportunities within a highly specialized battery technology organization.

Next Steps: To explore this opportunity confidentially, please contact Impel Talent or apply directly. Let’s work together to advance next-generation lithium-sulfur battery technology toward scalable, industrial deployment.
