    Maybe raw battery cost has reduced but installed storage is 30% more expensive than it was a couple of years ago, and it was too expensive then…

      probably when using carbon cathodes instead of cobalt, the energy density drops from 300wh/kg to just 150wh/kg, so u would need extra anode/electrolyte mass to store the same amount of energy.i bet that those prices hikes are a result of diversion from rare earth metal mining…but just a guess
