I've read dozens of papers on Li-S over the years because of how much incredible potential the technology seems to have. The "dirty little secret" seems to be not the charge cycles (which are less than, but similar to, other batteries), but the large amount of electrolyte required, which reduces the effective energy density of the battery. There are all sorts of papers reporting high-capacity and durable cathodes but fewer that address the electrolyte problem, so I'm curious to see what their plan for that is.

A few papers about the electrolyte problem are e.g.:

For utilities I don't imagine that electrolyte is a big issue as there is plenty of space and you aren't lugging them around like you are in an EV. Maybe their plan is to use it mostly for grid power?
