Postdoctoral Research Associate - Redox Flow Batteries and Membranes

Requisition Id13737

Overview:

We are seeking a skilled postdoctoral candidate to focus on developing new redox flow batteries concepts. In this role, you will concentrate on materials and chemistries suited for long-duration energy storage (LDES), specifically: Assembly, testing, and structural design of redox flow batteries; Membrane processing and electrochemical evaluation within the flow battery setup, including characterizations of ion transport and thermal and mechanical properties; Development of electrochemical methods to evaluate failure modes in these systems.

This position is available within the Energy Storage and Conversion Group (ESCG) in the Chemical Sciences Division (X060) at the Physical Sciences Directorate (PSD) of Oak Ridge National Laboratory (ORNL). The selected candidate will engage in daily collaborations across the laboratory, contributing to novel scientific directions in partnership with the team and sponsoring organizations. This role supports ORNL's mission to lead globally in energy storage science, addressing critical energy storage challenges vital for the economic and security interests of the United States.

You will work in CSD's state-of-the-art laboratories, which are equipped with facilities for solid-state and wet chemistry synthesis, physical vapor deposition systems, electrochemical testing modules, X-ray scattering equipment, and various spectroscopy and microscopy tools. This position also offers extensive opportunities to access world-class facilities and collaborate with staff scientists at the Center for Nanophase Materials Sciences (CNMS), the Spallation Neutron Source (SNS), and the Battery Manufacturing Facility (BMF). Applicants are expected to actively participate in writing reports, lead peer-reviewed publications in a timely manner, and maintain a strong commitment to upholding and promoting the values and ethics of our research community. Your research will be enhanced by interactions with other battery scientists, polymer chemists, computational chemists, and neutron scattering experts.
