I thought about this too and came to the conclusion that home and EV batteries probably have different requirements. For instance, a home battery might have to be more durable (so withstand more charging cycles) but on the flip side can be heavier. That said there might be synergies by repurposing worn out EV batteries as home or grid storage batteries.
