.JOB DESCRIPTION: CIC energiGUNE is recruiting a highly motivated PhD candidate to investigate and model degradation mechanisms in commercial sodium-ion batteries. The research will focus on identifying and quantifying ageing pathways in anodes, cathodes, and electrolytes and developing predictive models to simulate aging mechanisms and propose mitigation strategies to enhance battery performance and longevity. The successful candidate will conduct experiments, analyze data, and develop computational models to simulate these processes. The student will develop exceptional skills and expertise in the areas of electrochemical engineering and materials science during his/her studies. Main job functions: Design and conduct experiments to study the ageing mechanisms in commercial sodium-ion batteries. Analyze experimental data to identify key degradation pathways in anodes, cathodes, and electrolytes. Develop and implement computational models to simulate ageing processes. Collaborate with team members and external partners to validate findings. Present research findings at conferences and publish results in high-impact scientific journals. Contribute to the overall research activities of the department and participate in group meetings. Area: Electrochemical energy storage (EES) Group: Degradation mechanism, aging and safety group WHAT WE OFFER: We are offering a 3-year predoctoral contract and advantageous professional development opportunities with the possibility of a 1-year extension based upon satisfactory job performance, continuing availability of funds, and ongoing operational needs. Flexible working hours promoting work-life balance and self-organization. On-site work model with the option to telework. Full access to cutting-edge laboratory facilities and characterization platforms. The incorporation to a top research center in Europe that makes high-quality research and impactful contributions to the energy and sustainability fields. Professional and personal development: opportunity to attend seminars, international conferences, training courses, etc. Integrated, enthusiastic, international, and multidisciplinary environment. A welcome program that offers help with finding accommodation and addresses other aspects to help you integrate into the local environment (such as free language courses, assistance with the administrative procedures, help with schools for children…). TO APPLY: All applicants are invited to submit their application, a detailed curriculum vitae along with a motivation letter at this website: The selection process ends once the candidate is selected. CIC energiGUNE is committed to affirmative action, equal opportunity, and the diversity of its workforce. DESCRIPTION OF THE INSTITUTION: WHO ARE WE? WHERE ARE WE?
