About the role#
Enovix Corporation is seeking an R&D Intern to support the design, fabrication, testing, and analysis of lithium-ion batteries featuring silicon-based anodes. This role requires a hands-on approach to experimentation and the ability to work across fundamental science and product-focused development. You will collaborate with scientists and engineers to support the development of high-performance lithium-ion cells.
What you'll do#
- 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, and lithium inventory loss.
- Use materials characterization techniques such as SEM, TEM, XRD, XPS, Raman, FTIR, BET, or TGA.
- Develop data-driven recommendations to guide silicon anode material and cell design.
- Document experimental procedures, results, and conclusions in technical reports and presentations.
What you'll need#
- Current enrollment in a PhD program at a leading university, national laboratory, or research institute with a focus on batteries, electrochemistry, materials science, chemical engineering, mechanical engineering, or a related field.
- Research experience in lithium-ion batteries, preferably with 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.
Location & details#
- Location: Fremont, California.
- Work Modality: On-site.
- Employment Type: Full-time, paid internship.
- Duration: 3-6 months.
- Pay Range: $40-$45 per hour, depending on experience and qualifications.
