- Characterize and analyze electrochemical performance of new materials and formulations using testing techniques.
- Assess and improve safety, stability, and cycle life of electrolyte systems.
- Manage and communicate project progress independently and support product development for prototypes.
- Implement streamlined testing methods, such as Design of Experiments (DoE), to accelerate research and development.
- Mentor junior staff and provide technical leadership within the team.
- Integrate existing knowledge with new discoveries to facilitate development and problem-solving.
- Contribute to intellectual property development through invention disclosures and patent applications.
Requirements
- A MS or better level of understanding in Electrochemistry, Materials Science, Chemical Engineering, or a related physical science field.
- Minimum of 3 years of industrial or advanced academic experience post-MS focused on electrolyte or battery materials development.
- Strong knowledge of common lithium-ion electrolyte systems, including common lithium salts, solvents, and additives, and their specific roles.
- Experience applying physical-chemical methods to tackle formulation problems and understanding properties like density, viscosity, and ionic conductivity.
- Hands-on expertise in advanced electrochemical characterization, including Electrochemical Impedance Spectroscopy (EIS) and galvanostatic cycling.
- Proven experience working with moisture sensitive materials in a glovebox or dry room environment, and expertise in handling high purity chemicals.
- Proficiency in battery cell tests including coin and pouch cells, and scientific data analysis using statistical or scientific software.
- Ability to independently plan, execute, manage, and communicate progress on projects.
- Ability to support product development as required for the prototype-manufacturing team.
- Ability to design and develop electrolyte formulations compatible with high energy density lithium-ion anodes and high nickel content NMC cathode cell chemistries to achieve a long cycle life safely.
- Ability to design electrolyte systems to demonstrate improvements in safety performance, including dimensional stability during battery cycling and storage.
- Ability to provide technical assessment on existing electrolyte systems, additives, and lithium salts in high energy, high-capacity rechargeable lithium-ion cells.
- Ability to fully characterize coin and pouch cell performance using new materials and formulations.
- Ability to utilize electrochemical testing and analytical techniques to understand reaction mechanisms, failure modes, and potential benefits of new formulations.
- Ability to demonstrate the use of fundamental physical chemistry concepts and experimental techniques to provide promising electrolyte formulation strategies.
- Excellent organizational and communication skills to effectively communicate new concepts, findings, and project updates to the team, drawing actionable insights from discussions.
- Proven ability to serve as a technical mentor and leader to junior staff, guiding experimental design and professional development.
- Proven ability to actively integrate and synthesize existing in-house knowledge with new discoveries to accelerate development and problem-solving.
- Proactively contribute to the company’s intellectual property portfolio through invention disclosures and patent applications.
