Silicon Anode Battery R&D Intern

Enovix Corporation; Fremont (CA); On-site; USD 55,000 - 62,000; Full time

Benefits offered by this job

Paid internship

Job summary

Enovix Corporation seeks an R&D Intern to support design, fabrication, testing, and analysis of silicon-based lithium‑ion batteries. The role suits a PhD student or graduate researcher with hands-on electrochemistry and battery materials experience.

You will work across fundamental science and product-oriented development, collaborating with scientists, engineers, and leadership to advance silicon anode technology, with hands-on lab work and data-driven reporting.

Qualifications

• Enrollment in a PhD program focused on batteries or related field.
• Experience with lithium-ion batteries, especially silicon-carbon or advanced anode systems.
• Hands-on experience with battery cell assembly and electrochemical testing.
• Ability to analyze complex data and translate results into actionable technical insights.

Responsibilities

• Design and evaluate silicon-based anode materials, composites, binders, conductive additives, and electrode formulations.
• Fabricate electrodes and test cells (coin, pouch, etc.) for electrochemical evaluation.
• Perform battery testing including formation, cycling, rate capability, fast-charge, impedance, and diagnostics.
• Analyze capacity retention, coulombic efficiency, impedance growth, swelling, and other metrics.
• Investigate silicon anode degradation mechanisms (volume expansion, SEI, fracture, lithium inventory).
• Use characterization techniques (SEM, TEM, XRD, XPS, Raman, FTIR, BET, TGA).
• Develop data-driven recommendations to guide silicon anode material and cell design.
• Document procedures, results, and conclusions in technical reports and presentations.
• Collaborate cross-functionally with materials, cell engineering, process development and product teams.
