PhD in Long-duration instrumented operando cell XAFS studies of modified Co-free Cathodes : LNO and LNMO
The development of next-generation batteries for electric vehicle applications requires developing cobalt-free (Co-free) metal oxides that can provide higher energy capacities at high voltages. Reducing the reliance on cobalt addresses both the material costs and ethical concerns regarding the supply chain. Promising Co-free candidates are being developed within the Faraday Institution’s FutureCAT project. For example, layered nickel layered oxides (LNO) and high-voltage spinel (LMNO) are industry-aligned next-generation chemistries for Co-free high-performance i.e. high voltage and energy dense applications in the automotive industry. Increasing capacity retention and cycling performance is a critical issue for these classes of materials. Key to optimizing their performance for integration into commercial cells is understanding how morphology, dopants and surface coatings can improve capacity retention at high voltages i.e. > 4.2V. Advanced characterization techniques, such as operando x-ray studies in real-format battery cells, are required to distinguish the true redox electrochemistry from side reactions that can occur under realistic operating conditions.
This PhD project is aligned with the Faraday Institution’s FutureCAT collaborative project to characterize new cobalt-free Li-ion battery cathodes for next generation methods at Warwick University. The Energy Innovation Centre at WMG, Warwick University is a leading National facility for battery research across the R&D process from materials and electrochemistry through to application integration and recycling / second life. This project will perform cutting-edge fundamental electrochemistry & materials science of state-of-art batteries manufactured at WMG to develop instrumented pouch cell format cells with reference electrodes. These activities will include the application of a newly acquired state-of-art in house x-ray absorption fine structure spectrometer (XAFS) for in-situ battery studies on instrumented cells to complement the suite of analysis tools at WMG and Synchrotron studies at Diamond Light Source.
This 4-year fully funded PhD is supported by Faraday Institution Training Grant is funded from an Engineering and Physical Sciences Research Council (EPSRC) Training Grant awarded to the Faraday Institution as part of Industrial Strategy Challenge Fund (ISCF) Faraday Battery Challenge Funding. The project will be based in the Electrochemical Materials division at WMG, Warwick University and be supervised by Professor Louis Piper. Students will collaborate with the FutureCat consortium and are expected to be involved in cell manufacturing, testing and characterization. Applicants should have a top-level degree in Chemistry, Physics, Materials Science Engineering, or related subject. Experience with lithium-ion battery characterization and testing is desirable but not essential. To discuss the project informally, please contact Professor Piper email: email@example.com
