Internship | Development of hard carbons for Na-ion batteries

About this position

The contribution of renewable energy sources to the total energy generation is steadily rising. One of the issues of renewable energy sources, such as solar and wind, is intermittency and therefore electricity price variation. At TNO, we work on several aspects of the energy transition from energy generation to storage. The project described here is concerned with energy storage for next-generation beyond-Li batteries, specifically Na-ion batteries. Na-ion batteries have been gaining attention, with recent examples of battery cells developed by several companies. However, there is still a lot of research to do if we want to keep pace with demands for energy density, power density, durability, safety, and sustainability. Within this project, the aim is to create hard carbon anodes with high durability.

What will be your role?

In this internship, you will synthesize hard carbon and evaluate its electrochemical performance in Na-ion battery cells. You will relate the electrochemical properties of the material to the synthesis protocol, materials properties, and electrode preparation methods.

As for the experimental part, you will first develop a synthesis method for hard carbon materials. Afterwards, you will prepare the full electrodes and test the battery performance in coin cells under industrially relevant conditions. Under guidance of TNO, you will propose solutions to optimize the electrodes and their production process.
You will learn characterization and analytical techniques such as Scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM-EDX), X-Ray diffraction analysis (XRD), as well as electrochemical techniques such as cyclic voltammetry (CV) and battery testing
Minimum project duration is 6 months, starting as soon as possible. A more detailed plan will be drafted together with your academic supervisor. At TNO, you will work in Holst Center and in the Materials Solutions Department in Eindhoven.

What we expect from you

  • Practical experience in lab environment and hands-on skills are preferable, particularly with chemical synthesis and/or electrochemistry.
  • Interest in the energy transition.
  • High motivation, with a curious nature and a taste for problem-solving.
  • Good communication skills (in English).
  • The duration of this internship is at least 6 months.
