why Redflow is in trouble, page-8

There's nothing 'valid' or 'well researched' about that diatribe Brumbypat.
ZBMs are NOT 'gasseous' [sic], are about as 'noisy' as a hot water system, are a completely sealed system with efficient recombinators that do NOT require any different warning labels to a typical lead acid battery.
As a parent - a very safety focussed parent - and someone who does batteries of all types for a living, I would put in a Z-cell ANY day before ANY type of Lithium based system.

When will people understand that Lithium's propensity to explosively oxidize on contact with air or water has only been accepted as a trade-off because of it's very high energy density - it's light weight meaning that even though it's dangerous it is an excellent solution for mobile energy storage. For STATIONARY energy storage situations there is NO NEED AT ALL to take the risk of mounting lithium chemistry on your house or in your garage. The mass of the storage chemistry doesn't matter because it's STATIONARY (installation logistics aside of course)

Leaving aside the misinformation about container capacities, margins and projected sales, Ousia keeps trying to beat up pseudo-chemical scares about ZBMs and one really has to ask 'why?' This post is his second or third attempt to mislead and run specious scares on the same topic.

ALL energy storage chemistries have some degree of volatility. That's the point of them - the elements involved are chosen for their readiness to give up and receive electrons, reversibly. If you had milk and butter it would be very 'safe' but it WOULDN'T DO ANYTHING USEFUL in an electrochemical sense.

Let's also address this nonsense about Bromine. We put Bromine and it's mate Chlorine in our pools and spas. If you've ever drunk ANY carbonated soft drink with a citrus juice component (FANTA Sprite, SOLO eg.), guess what? You've drunk brominated compounds. You've ingested it. Are you dead? I wonder if Ousia has ever given Fanta to his kids?

In a previous post he talked about Bromine reacting with other elements in the environment to form 'ozone harming' gasses. That's correct (Well done Ousia! 1 fact correct out of twenty!) but if you've been to the beach and watched the waves roll in and the spray come off them...you've seen this natural process in action. The oceans are full of adsorbed, compounded and dissolved bromine and it undergoes this reaction Ousia mentions ALL THE TIME. Day and night. Forever. In kiloton quantities hourly.

Anyway, you get the gist. Perhaps he/she is genuine and ill-informed.
