What is lithium ion battery cell design?

Lithium ion battery cell design refers to the process of engineering the structure, components, and materials used to make lithium-ion batteries, which are widely used in electronics, electric vehicles, and energy storage systems. This involves selecting electrode materials, electrolytes, separators, and designing the cell's shape and size for optimal performance, safety, and longevity. Engineers in this field work to improve energy density, charging speed, thermal stability, and cost efficiency through innovative cell design. The process also includes considerations for manufacturability and recycling at the end of the battery's life. Effective cell design is crucial for meeting the varying demands of different applications and advancing battery technology.

What are the main teamwork and cross-functional collaboration aspects in a lithium ion battery cell design role?

Professionals in Lithium Ion Battery Cell Design often work closely with multidisciplinary teams, including materials scientists, mechanical engineers, and manufacturing specialists. Effective collaboration is essential, as design decisions must align with production capabilities, safety protocols, and performance requirements. Regular meetings and joint problem-solving sessions ensure that designs meet both technical and practical standards, while also allowing for continuous innovation. This environment enables designers to learn from various experts, broadening their skill set and fostering career growth.

What are the key skills and qualifications needed to thrive as a lithium ion battery cell design engineer, and why are they important?

To thrive as a Lithium Ion Battery Cell Design Engineer, you need a solid background in electrochemistry, materials science, and mechanical engineering, often supported by a relevant engineering degree or advanced studies. Experience with CAD software, battery modeling tools, and familiarity with industry standards (such as ISO and UL certifications) are typically required. Strong problem-solving, project management, and collaboration skills set candidates apart in this field. These competencies are essential to create safe, efficient, and innovative battery solutions that meet demanding performance and regulatory requirements.

What is the difference between Lithium Ion Battery Cell Design vs Battery Manufacturing Engineer?

AspectLithium Ion Battery Cell DesignBattery Manufacturing Engineer
Primary FocusDesigning battery cells, chemistry, and architectureOverseeing manufacturing processes and quality control
Required SkillsElectrochemistry, CAD, materials scienceProcess engineering, production management, quality assurance
Work EnvironmentResearch labs, design studiosManufacturing plants, production lines
Common CertificationsElectrochemistry, battery technology certificationsProcess engineering, Six Sigma, quality management

While Lithium Ion Battery Cell Design focuses on creating and optimizing battery cell architecture and chemistry, Battery Manufacturing Engineers implement and manage the production processes to ensure quality and efficiency. Both roles are essential in the battery industry but differ in their core responsibilities and work environments.

Job description

Battery R&D Internship
Enovix is seeking an R&D Intern to support the design, fabrication, testing, and analysis of lithium-ion batteries with silicon-based anodes. This role is well suited for a PhD student or graduate researcher with strong experience in electrochemistry, battery materials, cell testing, and failure analysis.
The ideal candidate will bring deep technical expertise in battery materials and electrochemistry, a hands-on approach to experimentation, and enthusiasm for addressing complex challenges in silicon anode commercialization.
The intern should be comfortable working across fundamental science, experimental execution, and product-focused battery development. The intern will collaborate closely with scientists, engineers, and technical leadership to support the development of high-performance lithium-ion cells.
Key Responsibilities
The intern will contribute to one or more of the following areas:
  • Design and evaluate silicon-based anode materials, composites, binders, conductive additives, and electrode formulations.
  • Fabricate electrodes and coin, pouch, or other test cells for electrochemical evaluation.
  • Perform battery testing, including formation, cycling, rate capability, fast-charge testing, impedance measurements, and diagnostics.
  • Analyze capacity retention, coulombic efficiency, impedance growth, swelling, and other key performance metrics.
  • Investigate silicon anode degradation mechanisms, including volume expansion, SEI evolution, particle fracture, lithium inventory loss, and electrode-level failure modes.
  • Use materials characterization techniques such as SEM, TEM, XRD, XPS, Raman, FTIR, BET, TGA, or related methods, as applicable.
  • Develop clear, data-driven recommendations to guide silicon anode material and cell design.
  • Document experimental procedures, results, and conclusions in technical reports and presentations.
  • Work cross-functionally with materials, cell engineering, process development, and product teams.

Required Qualifications
  • Currently enrolled in a PhD program at a leading university, national laboratory, or research institute with a strong focus on batteries, electrochemistry, materials science, chemical engineering, mechanical engineering, or a related field.
  • Research experience in lithium-ion batteries, preferably silicon-carbon or other advanced anode systems.
  • Strong understanding of lithium-ion battery fundamentals, including electrode design, interfacial chemistry, SEI formation, transport limitations, and cell degradation.
  • Hands-on experience with battery cell assembly and electrochemical testing.
  • Ability to analyze complex experimental data and translate results into actionable technical insights.

Preferred Qualifications
  • Direct experience with silicon anode materials, silicon-carbon composites, pre
  • lithiation, binder systems, electrolyte additives, or high-loading electrode design.
  • Familiarity with advanced diagnostic methods such as EIS, GITT, dQ/dV analysis, post-mortem analysis, gas analysis, or mechanical swelling measurements.
  • Experience using Python, MATLAB, JMP, Origin, or similar tools for data analysis.
  • Publications, patents, or conference presentations related to lithium-ion batteries or advanced anode materials.
  • Experience working in industry, a national laboratory, or a collaborative applied research environment.

What You Will Gain
  • Hands-on experience developing next-generation silicon anode lithium-ion battery technology.
  • Exposure to startup-style R&D, rapid experimentation, and practical cell development.
  • Opportunity to work closely with experienced battery scientists and engineers.
  • Experience translating academic research into commercially relevant battery technology.

This is a paid internship that will be onsite at our Fremont, CA office, with an expected duration of 3-6 months. The hourly pay range is $40-$45, depending on experience, qualifications, and other job-related factors.
