China handles this problem by moving batteries from EV use to storage use. Many batteries can still function well at low rates of charge and discharge which is common in solar and grid storage. See Yinlong LTO cells, they are apparently re-wrapped EV bus cells. LiFePO4 cells are also great for storage, although they may not be quite as good used.
