Right. The point is mass produced consumer devices we're familiar with have different constraints than a power grid so most people's existing familiarity with low cost retail batteries isn't all that relevant. For instance Lithium–air batteries have about the energy density of oil but comes with loads of problems that make them currently impractical for consumer devices. There's fewer hurdles however in making it power station ready. Same thing with liquid electrodes research. There could be large reservoirs that are on multiday flow cycles for capacity smoothing. It's like comparing a drainage pipe to a hydropower river dam, it's fundamentally a different problem space
