PhD: Functional interfaces in high-voltage sodium layered oxide cathode materials for SIBs

JOB DESCRIPTION:

CIC energiGUNE is recruiting a candidate to pursue a PhD within a MSCA Doctoral Network Grant - Agreement No. 101311389 with the European Commission.

The goal is to assess and mitigate degradation in high-voltage Na layered oxide cathodes (moisture instability, irreversible phase transitions, parasitic reactions with electrolyte) using interfacial strategies to enhance their electrochemical performance and enable their integration into high-voltage sodium ion batteries (SIBs).

The DC will engineer a stable, low-impedance cathode-electrolyte interphase (CEI) to suppress irreversible electrolyte consumption and enhance cycling and rate performance. Ex-situ interfacial solutions prior to battery assembly will be applied via different methods (chemical, mechanical, vapor deposition) and compared or complemented with in-situ CEI modifications (via tuned electrolyte formulations or sacrificial salts). CEI stability and Na⁺ transport will be thoroughly investigated.

Comprehensive S-L and S–S–L interface characterization (EIS, XPS and TEM, in cooperation with DC#2) is planned. In cooperation with DC#1 (anode materials) and DC#15 (electrolytes) full cells will be validated. Interfacial structure–function relationships will be further assessed using atomistic input from DC#7.

Main job functions:

• Performing high-quality research within the scope of the project.
• Reports/papers preparation for submission to peer reviewed journals.
• Presenting results in international conferences.
• Providing guidance to Master’s and visiting students when required.
