> For several reasons, including their relative bulkiness, vanadium batteries are typically used for grid energy storage, i.e., attached to power plants/electrical grids.
VRFBs' main advantages over other types of battery:
no limit on energy capacity
can remain discharged indefinitely without damage
...
wide operating temperature range including passive cooling
long charge/discharge cycle lives: 15,000-20,000 cycles and 10–20 years.
low levelized cost: (a few tens of cents), approaching the 2016 $0.05 target stated by the United States Department of Energy and the European Commission Strategic Energy Technology Plan €0.05 target
We’re currently experiencing a Cambrian explosion in battery tech. As the technology matures, and we establish a closed loop ecosystem to build and then recycle these systems, longevity can improve over time. To get better at something, you must first suck at it, and 10-20 years is not an immaterial service life for an asset that just sits and hums with no moving parts.
I agree if we were talking about a motor or a pump, but it seems like batteries basically devastate the environment every time we make one, and doing that millions of times every ten years is probably not great. (But I don't know anything about that specific battery technology.. perhaps it's just saltwater and two dissimilar metals.)

(and yes, there are disadvantages too)See also NPR's story: The U.S. made a breakthrough battery discovery — then gave the technology to China https://www.npr.org/2022/08/03/1114964240/new-battery-techno...
