About the Role

  

Coreshell's metallurgical Silicon anode technology delivers high capacity, fast-charging, and superior safety. Our low-cost Silicon-dominant batteries have higher energy density, superior intrinsic thermal safety, and significantly lower cost/kWh compared to current LIBs. Coreshell's Si anode material is lower than the cost of graphite and utilizes the largest abundant critical mineral supply in the US and Europe. We strive to transform the global energy and transportation market by enabling cost effective and secure domestic battery supply.

 

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 electrode 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
