Job description

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 lower than 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.

Position: We are looking for a Battery Technician - Electrode Production with large-scale battery electrode manufacturing and/or electrode process development experience and program language skills to carry out electrode fabrication, data visualization, and process development work. Ideal candidate is self-driven, detail-oriented, proactive in problem solving and able to wear many hats.

• Perform routine quality control tests on fabricated electrodes.
• Characterize electrode features and defects using materials analytical techniques such as SEM/EDX, adhesion testing, resistance measurements, etc.
• Design and perform experiments to define optimal process parameters for cell performance and processing capabilities.
• Clean equipment and tools after electrode production runs in a timely manner.
• Record parameters used and observed in electrode fabrication processes in runsheets.
• Manage inventory of manufacturing consumables.
• Follow and maintain standard operating procedures (SOPs).
• Perform short, manual tasks moving electrode rolls and consumables between machines and storage.
