Maybe not for current chemistry lithium batteries but for batteries in general prices will probably keep dropping as they find different ways to save cost like using sodium instead of lithium. As solar and wind electricity production keeps getting cheaper and more home installations keep happening I think the demand for cheap home stationary batteries will start growing exponentially.

Hopefully we are not far from the tipping point cheap batteries are needed for it to happen though where world yearly electricity consumption growth can be met by renewables alone and we can start closing more and more coal power plants.
