San Leandro, CA, USA
USD 22-32 / hour
Posted on Oct 9, 2025
Position: R&D Intern
Reports To: Research Engineer III

Coreshell's metallurgical Silicon anode technology delivers high capacity, fast-charging, and superior safety. Our low-cost liquid-phase nano-coating addresses critical electrode-surface degradation issues and enables batteries with a Silicon-dominant anode that have higher energy density, superior intrinsic thermal safety, and significantly lower cost/kWh compared to current LIBs. Our Si anode material is 50% the cost of graphite and 100% domestically sourced. We strive to transform the global automotive market by enabling low-cost and long-range EVs as a first step towards net-zero sustainability in the near future.

The Position: Coreshell is investigating novel methods of maximizing the performance of metallurgical grade silicon as an anode material for lithium-ion battery applications. The project will focus on advancing battery electrode materials by optimizing their composition processing techniques, and testing in electrochemical cells.

Project Goal: The project aims to study how cathode material properties and processing affect battery performance through materials characterization and cell testing.

Responsibilities:
  • Formulating, preparing electrode slurries, and applying coatings to current collectors.
  • Assembling coin cells using optimized cathode materials.
  • Characterizing materials using techniques such as SEM-EDX, TGA, and particle size analysis.
  • Assisting with setup, testing, and debugging of new processing operations.
  • Analyzing data and presenting it to the team members.
  • Maintaining detailed experiment records.
  • Collaborating with cross-functional teams to meet project goals.
  • Adhering to lab safety rules and regulations and maintaining a safe work environment

Requirements:
  • In process or obtained a Bachelor’s or Master’s degree in chemistry, chemical engineering, or a related field.
  • Hands-on experience working in research laboratories, glovebox handling.
  • Creative, self-driven, “out-of-the-box” thinker with a long history of problem-solving and an ability to wear many hats.
  • Strong interpersonal and communication skills.

Desired experience:
  • Experience with coin cell building and electrochemical analysis.
