Re: Why Li-ion?
A depleted pack still has lots of utility in a home situation. Consider a Tesla S 60 pack, when it's down to 80% of capacity it can still store enough power to run the average home for nearly 5 days (48kWh with the average domestic power usage being 3500kWh/year). The original owner gets a nice big trade-in value on the cost of a new pack. The domestic owner gets a cheap pack, that is comparatively small and light (so it doesn't take up too much space or require reinforced floors). It's not hard to see the value in the proposition.
