At present the grid/stationary storage battery market is essentially a sideline for vehicle battery makers.[1] Vehicle batteries have to balance between energy density, power performance, tolerance for temperature extremes, structural factors (vibration), safety, cycle life, and cost.
As stationary batteries become a market of their own, some of these requirements can be relaxed; engineers can focus on capital cost and cycle life. (This is already happening with early-stage technologies like carbon polymer, redox flow, and molten salt, which are already competitive with lithium chemistries.)
This allows, and will almost certainly result in, speeding up the rate at which battery costs fall.
1. Similar to the situation for PV cells up to about 2004 - 2005: they were a sideline business for wafer makers focused on logic semiconductors. After crossing over to having their own silicon production (by 2009) the fall in PV cell costs accelerated.
