Offer Description:

CIC energiGUNE is recruiting PhD candidates to pursue a doctoral thesis focused on the study of buried electrode/electrolyte interphases in next-generation sodium-ion batteries.

Main job functions:

- Design and execution of electrochemical experiments in sodium-based battery systems (coin cells, electrolyte formulations, cycling protocols)
- Development and application of solid-state NMR methodologies (static and MAS) for the study of SEI and CEI formation and evolution
- Implementation of in situ and operando NMR experiments under realistic electrochemical conditions
- Analysis of electrolyte degradation products using liquid-state NMR
- Correlation of spectroscopic results with electrochemical performance and degradation mechanisms
- Collaboration with multidisciplinary teams and use of complementary techniques (XPS, TEM, SEM, etc.)
- Preparation of scientific publications and participation in international conferences

Area:Electrochemical Enery Storage and Conversion (EESC) and Characterization Platforms

- Experience in electrochemical techniques and battery testing (e.g., coin cells, cycling)
- Previous experience in solid-state or liquid-state NMR
- Familiarity with air-sensitive sample handling (e.g., glovebox work)
- Knowledge of advanced characterization techniques (XPS, SEM, TEM,



etc.)
- Interest in method development and data interpretation

Specific RequirementsCANDIDATE PROFILE:

- Master’s degree (or equivalent) in Chemistry, Physics, Materials Science, or a closely related field
