Hi Guys,
My name is Daniel, I am a chemist with a passion for battery technology and currently trying to build a highly efficient Zinc-Bromine battery at home using readily available materials. I have a blog where you can follow my progress (https://chemisting.com/). I am using a DIY USB potentiostat/galvanostat (read about how to build it herehttps://www.sciencedirect.com/science/article/pii/S2468067217300317)in order to properly characterize the batteries I build and in this way systematically modify/improve my builds.
I am using Swagelok cells for the construction of the batteries (0.5 inch diameter).This is the current configuration I have tested:
So far I have achieved a 96% Coulombic efficiency, although my specific capacity sucks, at around 1.0mAh/g of cathode material. I am going to change to a Zn anode and to carbon paper cathodes (see my latest blog post), which should help increase the specific capacity by a factor of 10-100x.
Any suggestions/comments/questions are welcome!
