I am going to study vanadium because of this video 🤗🤗

good video-- thank you

Wow........a short store long ......long storie short......i love what u all are doing n ........voltage..?.......?......that cell look like a heart.......i heard if u change temperature. .....u get more power........? Is that a polypropylene membrane??? Cheers

Error at 1:00. it should read - e (minus) instead of +e.

could u please tell me, where did u buy this special flow half cell for ur stack?! cant find any online...

Hello, I'm working about designing vanadium reflow batteries . How can I get this solidworks drawning or this drawing dimensions

Where did u buy the half cells and the carbon foam?

@vyassinghal1949 8 years ago (edited)

Hello ESA ..can you please tell me more about the half cell which you have used in the project. As i am not able to get that component

Do you use the same volume in each reservoir, or is one double the other?

Hello there, congratulation for the project.
The membrane that separate the different electrolites what it is???

What was the CAS of the Vanadium Oxide?

What alternative proton exchange membranes are there?

What does "mass transport limit" mean?

If I want to build one for myself what info/direction can you give me to build one?

Hi, may you give one of your e-mails,please? I would like to ask some questions that's why i study v-rfbs,too. I am a MSc student and am going to make v-rfb cells and test. Please :)

@MaxAigner 10 years ago

how much are the material costs of the battery and how much kWh does it storage?
I am not sure if I skipped this information in the video but it would be quite interesting probably for a lot of people, I guess. (?) :)

Hey guys. I am a student in Chemical Engineering at the University of Pretoria in South Africa. I happen to be working on a project which deals with a vanadium redox flow battery. I am having trouble with my electrolyte solution. I would like to know if it is possible for you to shed some light on the electrolyte with regards to the methods you used and the concentrations of the compounds. My problem so far has been the low solubility of Vanadium pentoxide. I tried to dissolve it in 3M sulfuric acid but I'm getting a suspension, rather than a solution. Any tips would be highly appreciated. Regards. :-)
