About this position
The Department of Chemistry at Uppsala University’s Ångström campus offers a research-intensive environment with a strong international profile, external collaborations, and activity across multiple programs. This PhD project is embedded in that setting and focuses on the chemistry and electrochemistry of next-generation sodium-ion batteries.
The project addresses a key challenge in sodium-ion battery development: how to improve energy density and long-term stability by removing the conventional anode and moving toward anodeless cells. The research aims to support the commercial viability of these batteries by studying the stability of sodium metal anodes and by developing approaches that enable high-energy-density, sustainable batteries free of critical raw materials.
The doctoral work will combine fundamental battery science with device-oriented development. The student will work on electrolyte design and characterization, electrochemical testing of anodeless sodium-ion batteries, and the construction of single- and multi-layer pouch cells. The project also includes advanced operando methods, especially optical microscopy and electrochemical dilatometry, to study sodium deposition and stripping during cycling.
The position is based at Uppsala University and includes close collaboration with industrial partners Altris AB and Polestar. A six-month research placement at Humboldt University of Berlin is part of the project, providing training in electrochemical dilatometry within the first three years of the PhD. Research visits to Sweden and Germany are also included as part of the work.
The doctoral student will contribute to experimental development across liquid and gel electrolytes, charge/discharge protocol design, and near-commercial cell development, within a collaborative battery research environment at the Department of Chemistry - Ångström.

What's required
Applicants must have a second-cycle degree in Chemistry, Engineering, Materials Science or an equivalent field, or have completed at least 240 higher-education credits including at least 60 credits at master’s level and an independent project worth at least 15 credits, or have acquired essentially equivalent knowledge. The candidate must have very good oral and written English, good organisation and time management skills, experience working in a laboratory environment, and experience with battery materials. Merit is given for collaborative skills, drive, independence, and relevant experience with anodeless or metal-ion batteries, electrochemical plating/stripping, electrolyte development, multi-layer pouch cell assembly and characterisation, and operando characterisation techniques; sodium-, potassium- or lithium-ion experience is most relevant, with calcium- and magnesium-ion experience also considered meritous.
