About This Role
This research scientist role focuses on qualifying anode graphite material within battery cells. It involves collaborating with technical teams across regions to investigate material mechanisms and create technical solutions for applications such as electrical car batteries and energy storage systems. The position supports the iteration and optimization of anode graphite material performance at the cell and electrode level, and works with business teams to commercialize products.
Responsibilities
- Lead labs in conducting coin cells, pouch cells, and full cells using artificial graphite, silicon-carbon, hard carbon, and other anode materials
- Conduct systematic evaluation of anode graphite performance, including first-cycle coulombic efficiency, capacity, compact density, swelling, charging rate, high/low temperature performance, and cycle life
- Conduct cell performance tests and failure analysis, including root cause identification through advanced characterization and electrochemical testing, and lead DOE (Design of Experiments) design and performance validations
- Conduct qualification of anode materials in different cathode systems (LFP, NCM, etc.), and assist in the optimization of N/P ratio, electrode structure, electrolyte system, and interface stability
- Validate anode materials with various electrolyte systems, analyze correlations of solvents, lithium salts, and functional additives on anode materials, resistance, cycle stability, lithium precipitation, and side reaction behaviors
- Understand the structure-properties relationship between anode material and the dispersion of electrode slurries, electrode coating, and calendaring processes
- Identify processing risks and provide optimization solutions
- Based on testing results, identify material-level, interface-level, and cell level technical issues, and collaborate with internal technology teams to upgrade coating, modification, and size control on particles
Requirements
- Master's degree, PhD or above in Materials Science, Electrochemistry, Chemical Engineering, New Energy Materials, or related fields
- At least 3 years of hands-on experience in lithium-ion battery anode material application development and cell qualification related technologies
- Experienced with the electrochemical characteristics of various anode materials
- Proficient in cell preparation, electrochemical testing, data analysis, and key performance analysis methods
- Strong cross-regional team collaboration skills
- Fluent in English (listening, speaking, reading, and writing) for smooth cross-regional technical communication, meetings, and technical documentation output
- Prior work experience in an anode factory or battery cell maker, with participation in cell development, anode material selection and electrochemical system qualification is preferred
