Materials Engineer - Cell Wet Electrode

Job Description

Job Responsibilities

• Fabricate laboratory and pilot-scale wet anode electrodes in support of research builds
• Develop binders for electrode slurries, and formulate and mix those slurries for each build
• Operate a roll-to-roll coater, set line conditions, and correct coating defects
• Handle electrode webs and rolls, including loading, unwinding, and slitting or punching as required, and store finished electrode under a traceable identifier
• Record formulation, process parameters, material identifiers, and deviations on cell travelers and build sheets
• Operate, clean, and perform routine maintenance on laboratory and pilot mixing and coating equipment
• Perform in-process checks of slurry quality, electrode loading, thickness, and visual quality, and submit samples for electrochemical and mechanical evaluation
• Prepare and revise operating procedures for the slurry process and the roll-to-roll coater
• Maintain a clean work area and comply with solvent-handling and personal protective equipment requirements, including use of a respirator or powered air-purifying respirator when required by the process
