Advent calendar - December 8th - Dr. Peter Bramwell

08 December 2021

In the Zernike Institute Advent Calendar, we are presenting 24 short spotlights in December. In these specials, we highlight PhD students, postdocs, and technicians of our research groups - providing a glimpse into their typical day at work. In Episode 8 meet Dr. Peter Bramwell.

I am working as a postdoctoral researcher in the Materials Chemistry group at Rijksuniversiteit Groningen. My research focuses on electrochemical processes in batteries. My days usually start with checking on the batteries I already have running their charge/discharge cycles, followed by planning out and preparing my next measurements. Once I have all of my batteries running I can then dive into the resulting data. Based on what I have learned from my data I can design or adjust my next experiments.

My work concerns nickel-iron batteries containing an iron sulphide additive, a more cost-effective alternative to Li-ion batteries as they are comprised of abundant and inexpensive materials. This makes them very promising for establishing a sustainable society, as long as we can solve some of the sulfur-induced self-discharge issues. I aim to achieve this by understanding the various mechanisms involved in the charge-discharge processes of the battery. I use a wide variety of techniques to achieve this such as electrochemical testing, X-ray diffraction, X-ray spectroscopy and microscopy. The most interesting of these are operando techniques which allow me to see what is happening in the battery in (almost) real-time.
