Zusammenfassung

The Helmholtz-Zentrum Berlin (HZB) invites applications for a Postdoc (m/f/d) in battery electrochemistry at our Berlin site. You will work on Li-S pouch cells from materials characterization to cell assembly within an interdisciplinary consortium of industry and academia.

Applicants should hold a PhD in electrochemistry or closely related fields with strong battery research background, and have hands-on experience with 2/3-electrode cells, operando testing, SAXS/WAXS, and pouch cell testing.

Qualifikationen

• PhD in electrochemistry or closely related field with strong electrochemistry and battery research background
• Experience with advanced characterization and structure–property–performance relationships at multiple operation levels
• Hands-on experience with 2/3-electrode battery systems, pouch cell research and data evaluation
• Development of new cell formats for testing electrode materials and electrolytes; familiarity with pouch test cell testing
• Structural characterization methods like SAXS/WAXS during battery cycling
• Proficiency with Origin, Windows and Office tools
• Excellent written and spoken German and English; strong publication record

Aufgaben

• Advanced structural characterization of cathode materials from powders to electrodes for Li-S pouch cells using various scattering techniques
• Preparation and assembly of single- and multi-layer Li-S pouch cells
• In-situ/operando electrochemical performance tests of Li-S pouch cells (galvanostatic charging/discharging, potentiostatic and impedance spectroscopy)
• Development of operando cell formats for testing novel electrode materials
• Summarize, present and publish results in German and English

Jobbeschreibung

Achieving climate-neutrality within the next 20 years necessitates an innovation boost for the development of highly efficient, scalable, low-cost, and sustainably produced energy technologies. Polymer materials play a central role in this process.Energy storage and conversion materials, particularly sustainable batteries, play a central role in this context.

We are looking for aPostdoc (m/f/d) in battery electrochemistryfor our site in Berlin, Germany. The Postdoc position offers a unique opportunity to address critical challenges by integrating cutting-edge materials research with the practical development of cells for Li-S batteries within an interdisciplinary consortium of industry and academic partners, all the way to the working principles of full Li-S pouch cell assemblies at Technology Readiness Level 5.

• Advanced structural characterization of cathode materials from powders to electrodes for Li-S pouch cells with different scattering techniques
• Preparation and assembly of single and multi-layer Li-S pouch cells
• in-situ/operandoelectrochemical performance of Li-S pouch cells (Galvanostatic charging and discharging, potentiostatic and galvanostatic impedance spectroscopy)
• Development of anoperandocell format for testing novel electrode materials
• Summary, presentation and publication of results in German and in English

Your Profile

• PhD degree (or in finalizing stage) in electrochemistry, physical chemistry, chemistry, materials science and engineering or a closely related field, with strong electrochemistry and battery research background
• Strong motivation in advanced characterization, structure-property-performance relationship at different levels of operation, fromex-sutotooperando
• Profound hands‑on experience in the operation and evaluation of 2 and 3 electrode battery systems assembly, single‑layer and multi‑layer pouch cell research and data evaluation
• Demonstrated experience in the development of a new cell format for testing novel electrode materials and electrolytes. Testing and standard characterization techniques of pouch test cells
• Implementation of a structural characterization analysis methods like small- and wide-angle scattering to investigate during battery cycling
• Computer skills, including Origin, Windows and Office
• Very good knowledge of written and spoken German and English
• Very good publication record and ideally experience in battery company as research and development intern
• Experience in presenting scientific content in English

You demonstrate a high level of commitment, initiative, problem‑solving skills, and a willingness to familiarize yourself with diverse areas of responsibility. You are characterized by your teamwork skills, reliability, independence, and communication abilities (including proficiency in English).
You enjoy working in an interdisciplinary, international team within a diverse and dynamic work environment.

Your Benefits at HZB

• International/diversity-sensitive working environment at a Helmholtz Institute
• Opportunity to contribute to the development of novel materials and technological solutions for a climate-neutral future together with top international researchers
• Career‑enhancing networking opportunities and individual support and assistance programmes
• Good work‑life balance through counselling services on family and career and flexible working time models: Flexitime, part‑time, hybrid working
• 30 days paid leave
• Health management, company pension scheme (VBL), subsidy for the Deutschlandticket/Jobticket
• Payment in accordance with the collective agreement for the public sector (TVöD‑Bund)

Fixed term contract for 12 months. The salary is based on the Collective Agreement for the German Public Service (TVöD‑Bund).
