Talk:Vanadium redox battery

message: I added a link to vrbpower.com a manufacturer of these types of batteries. It was removed as spam. I disagree with that. This is not exactly a well known topic and a link to one of the few big names in the field would help give some context. —The preceding unsigned comment was added by 149.99.63.218 (talk) 23:26, 8 March 2007 (UTC)
replies: text: Wikipedia is NOT a business directory. The article is not about that company. A link to their website does not add to the encyclopedic[sic] content and is not appropriate per the external links guidelines. VRB Power Systems Inc. spammed before, and their links were removed, not only by me. Interesting that only 6 days after, a corporate performance training company, also Canadian, inserts the same links again. Femto 13:03, 9 March 2007 (UTC)

thread_title: why vanadium?

message: The various figures quoted for energy density or specific energy do not agree with each other. Which are correct?
In the info box in the top section, 10-20Wh/kg is quoted (which seems low in comparison to other figures that I have seen.
In the Energy Density section, 25Wh/kg is stated as the figure for current in-production units with research suggesting 35 or higher.
On a more pedantic note, the 'Energy Density' section exclusively quotes specific energy ratings.  — Preceding unsigned comment added by Andy Maybury (talk • contribs) 11:45, 19 February 2016 (UTC)

message: I'm curious what the masses of the compounds are in these batteries, especially how much elemental vanadium there is per liter. I can't seem to find this answer. 
https://www.google.com/search?q=vanadium+grams+per+liter+battery
UPDATE: somewhat answered my question: 
"By comparison, to make the electrolyte solution for a VRFB about 145 grams of vanadium pentoxide per litre is needed. For a 1.6MWh flow battery that’s equivalent to 15 tonnes."

thread_title:  mass of vanadium in these batteries 

message: In the Applications section of this article the following sentence has no meaning: "Economically neither the UPS or frequency regulation applications of the battery are currently sustainable alone, but rather the battery is able to layer these applications with other uses to capitalize on various sources of revenue."   
'Sustainable' in what way?   Does any battery 'capitalize' on revenue?  It appears to be muddling between batteries and the battery production industry.   The sentence should be reworded (possibly as two or more sentences) or removed.  FreeFlow99 (talk) 13:05, 9 June 2020 (UTC)

message: "...the levelized cost of energy ... is typically in the order of a few tens of $ cents or € cents..."   But LCOE needs to be expressed in terms of cost per unit energy (e.g., dollars per kWh, euros/megajoule, etc.). Do we have a source for LCOE in meaningful units?
