JOB DESCRIPTION


Division: Arkema Inc.

Department/Business Group: Corporate Research

Job title:

Postdoctoral Scientist - Battery Technology and Material

Situation in organization

Individual formally reports to the Scientific Director and is part of a team led by a Principal Scientist at the King of Prussia Research Center; they will work closely with Arkema's global team.

Job dimensions

The scientist will support new lithium-ion battery electrode and separator developments, cell building, and electrochemical testing at Arkema reach center. The scientist will be responsible for establishing structure-property and performance relationships between the individual constituent of the electrode and solvent-free-processes (either aqueous or dry) and actual cells performance. The scientist will work closely with other R&D teams in Arkema. Responsibilities of this position included:



  1. Physical/chemical characterization of key constituent (i.e. binder, conductive carbon, high nickel active materials, nano-scale metal oxides, separate, electrolyte), identifying of main attributes, and their compatibilities with solvent-free processes

  2. Design and development of solvent-free formulation /optimization (either for aqueous or dry processes) and fabrication of electrodes, or electrodes/separator composite to achieve energy density and calendar-life targets performance

  3. Design, assembly, and the testing of different cell formats, and interpretation of results to guide and support battery development

  4. Conduct electrochemical diagnostics and post-mortem cell analyses to identify failure mechanisms and suggest corrective actions.



Activities


  1. Contribute effectively to product development efforts that are focused on testing and optimizing new binders, separators, electrolytes, and conductive carbons in solvent-free processes (either aqueous of dry) suitable for high-energy lithium ion batteries.20%

  2. Develop and carry out characterizationtechniques, which can identify the key features needed for solvent-free processes to manufacture high-energy lithium ion batteries. 20%

  3. Develop, implement, and conduct formulation optimization, electrode fabrication, cell manufacturing, and testing methods that can predict how new components will perform in high energy battery systems. 20%

  4. Provide broad technical knowledge, serve as a technical, and cell expert that can apply fundamental knowledge to advance Arkema's project in development of new materials and solvent-free processes (either aqueous or dry) for high-energy batteries. 25%

  5. Work in multi-disciplinary team, interpret analytical data and prepare reports using materials characterization techniques including rheological techniques, SEM, ICP, FTIR, DSC, TGA, XPS, titration, chromatography, porosity, surface characterization, electrochemical techniques such as IES, cyclic voltammetry, conductivity, and impedance measurements at different SOC. 15%



Context and environment


The position is part of a team working on developing new materials and solvent-free processes (either aqueous or dry) for high-energy batteries. The candidate will work collaboratively with other scientists and technical staff at all levels in a hands-on laboratory research environment.
