Hello Anna! Could you tell us about yourself and your background?
– Sure! My name is Anna and I am a twenty-six-year-old student. I grew up in Hudiksvall, but I have spent the past three years in Stockholm studying Chemical Engineering at KTH Royal Institute of Technology. This semester I am doing my bachelor thesis at 2D fab, which so far has been both challenging and fun!
Please elaborate, what is your bachelor thesis about?
– I’m researching a production process for silicon-nanographite based anodes in lithium ion batteries. Today, graphite is the primary material used in anodes for lithium ion batteries, but lately researchers have been looking at exchanging the energy carrier from graphite to silicon, since it can store much more energy. Unfortunately, a method that allows a large-scale production has been hard to come up with. But during fall 2019 researchers from Mid Sweden University published an article on a scalable process for nanomaterial-based anodes, where silicon nanoparticles were grown on graphene flakes. What I do is to investigate the production process that they used. The questions I seek answers to are “can this process be recreated?” and if so, “what parameters can be regulated to improve results and/or simplify the process?”
As we transition from fossil energy to greener alternatives, the need for large-scale energy storage systems increases
In your opinion, what is the best-case scenario for graphene enhanced batteries?
– One of the best-case scenarios is that they will contribute to a more sustainable society. As we transition from fossil energy to greener alternatives, the need for large-scale energy storage systems increases. Most of the electricity we get from solar cells and wind power can only be used right away. Since we cannot control the weather, we need equipment that can store the energy so that we can use it as we please. In the best of worlds, graphene will play the key part in future energy storage systems, that will let us do just that.
