Battery Modeling Engineer information

What is a battery modeling engineer?

Battery Modeling Engineers are professionals who design, develop, and optimize mathematical models that simulate the behavior and performance of batteries. They use these models to predict battery life, efficiency, safety, and performance under various conditions, helping to improve battery technology for applications like electric vehicles, consumer electronics, and renewable energy storage. Their work often involves collaborating with chemists, electrical engineers, and software developers to create accurate simulations and guide the development of new battery technologies.

How does a battery modeling engineer typically collaborate with cross-functional teams in the development process?

Battery Modeling Engineers frequently work alongside electrochemists, hardware engineers, and data scientists to develop and refine battery systems. They translate experimental data and design requirements into simulation models, ensuring alignment between theoretical predictions and real-world performance. Effective communication and regular meetings are essential, as Battery Modeling Engineers often provide critical insights that inform design decisions, troubleshooting, and optimization of battery performance. This collaborative environment fosters innovation and helps accelerate product development cycles.

What are the key skills and qualifications needed to thrive as a battery modeling engineer, and why are they important?

To thrive as a Battery Modeling Engineer, you need a strong background in electrochemistry, physics, and advanced mathematics, typically supported by a degree in engineering or a related field. Proficiency in simulation tools such as COMSOL Multiphysics, MATLAB, and Python, along with familiarity with battery management systems, is essential. Strong problem-solving skills, attention to detail, and effective communication help you collaborate and solve complex battery performance challenges. These skills are crucial for designing accurate models that drive innovation and efficiency in battery technology.

What is the difference between Battery Modeling Engineer vs Battery Test Engineer?

AspectBattery Modeling EngineerBattery Test Engineer
CredentialsDegree in Electrical, Mechanical, or Chemical Engineering; knowledge of modeling softwareDegree in Electrical, Mechanical, or Chemical Engineering; experience with testing equipment
Work EnvironmentDesign labs, simulation environments, R&D departmentsTesting labs, quality assurance, product validation
Industry UsageBattery development, simulation, and optimizationProduct testing, validation, and quality control
Search/Comparison IntentFocus on modeling and simulation skillsFocus on testing procedures and validation processes

The main difference between a Battery Modeling Engineer and a Battery Test Engineer lies in their focus areas. The Battery Modeling Engineer specializes in creating simulations and models to predict battery performance, while the Battery Test Engineer conducts physical tests to validate battery quality and safety. Both roles are essential in battery development but serve different stages of the product lifecycle.

Job description

We invite applications for a Postdoctoral Appointee position in the Chemical Sciences and Engineering Division (CSE) at Argonne National Laboratory. Working under the guidance of a supervisor, the successful candidate will conduct research focused on meso‑ and macroscale mathematical modeling of next‑generation batteries, while leveraging advanced artificial intelligence (AI) tools to accelerate scientific discovery. Research areas include solid‑state batteries with lithium and sodium metal anodes, as well as the morphology evolution of materials coupled with electrochemical and mechanical phenomena. The selected candidate will develop computational models at the mesoscale and/or macroscale based on the principles of mass, momentum, and energy conservation to describe processes such as morphological change, dendrite growth, side reactions, delamination, and related behavior in hard and soft materials. A strong emphasis will be placed on the integration of AI methods and agentic workflows into model development and scientific analysis. This position offers the opportunity to collaborate closely with experimental teams working in areas such as electrochemical characterization and synchrotron analysis, as well as with theoretical researchers specializing in atomistic simulation, density functional theory (DFT), and ab initio molecular dynamics (AIMD). The successful candidate will also engage with collaborators across Argonne, other national laboratories, universities, and international research institutions.

Key Responsibilities
  • Develop mesoscale and/or macroscale computational models for battery materials and processes
  • Implement models and perform numerical simulations
  • Analyze and interpret simulation and experimental data
  • Integrate AI tools and workflows to enhance modeling and accelerate learning
  • Collaborate with interdisciplinary experimental and theoretical research teams
  • Prepare manuscripts for submission to peer‑reviewed journals
  • Present research findings at scientific conferences and meetings
  • Prepare reports, presentations, and technical summaries for group meetings and sponsor reporting requirements
Position Requirements
  • Recent or soon‑to‑be‑completed PhD (within the last 0‑5 years) in Chemical Engineering, Mechanical Engineering, Materials Science, Chemistry, or a related field
  • Deep understanding of electrochemistry, electrochemical engineering, and battery science
  • Strong experience in developing computational models based on mass, momentum, and energy balance principles
  • Strong skills in applying AI tools and agentic workflows to scientific research
  • Some experience in proposing, planning, and designing experiments
  • Demonstrated ability to process, analyze, and interpret research results
  • Strong skill in formulating and solving scientific problems
  • Excellent written and oral communication skills
  • Ability to model Argonne’s core values of impact, safety, respect, integrity, and teamwork

As an equal employment opportunity employer, and in accordance with our core values of impact, safety, respect, integrity and teamwork, Argonne National Laboratory is committed to a safe and welcoming workplace that fosters collaborative scientific discovery and innovation. Argonne encourages everyone to apply for employment. Argonne is committed to nondiscrimination and considers all qualified applicants for employment without regard to any characteristic protected by law. All Argonne offers of employment are contingent upon a background check that includes an assessment of criminal conviction history conducted on an individualized and case‑by‑case basis. Individuals may be required to obtain a government access authorization that involves additional background check requirements; failure to obtain or maintain such authorization could result in the withdrawal of a job offer or future termination of employment.
