Flow-Batterie

Here you can get 3D printed parts for making your Flow Battery prototype . The model is great for your experimental flow battery concepts like vanadium redox flow battery, all iron flow battery, zinc bromine or zinc iodine flow battery and so on.

The design is designed so that can hold two electrolyte tanks which holds two glass tubes in size of 140 x 25 mm You can get it from ebay ot amazon). Two peristaltic pumps (https://www.ebay.com/itm/352994950390) and a cell or a cell stack. But in case that you experiment with a semi flow battery concept where only one electrolyte tank and one pump is used, then you can connect the cell to only one tank and pump.

For making the cell I recommend that the cell parts are printed with resin printer. In case that you use positive and negative electrolyte then one cell is made from two pieces of reactor plate and two pieces of end plates. Between each cell piece you need to place a gasket which is made from neoprene or silicone gasket in the thickness between 0.5 to 1 mm.

PLEASE NOTE:
I recommend to print the files with the name: tank and pump holder, tank holder and tank holder part 2 with PLA or PETG.
And the files with the name: reactor plate, end plate and reactor plate 2 is better to print with some resin printer (with ABS like resin) because it has better chemical resistance.
The PLA or PETG are not resistant to acid or alkaline based electrolytes and will be dissolved in a short time. But in case that you will use some neutral salt electrolyte in the battery then the cell parts can be printed also with FDM printer
