The main advantage of Lithium Ion is the high energy density which is good for reducing the weight of laptops and electric cars but doesn't seem that useful in a house, especially when you compare it with cheaper and longer lasting battery technologies.
This feels more like them trying to find a new business line for their existing technology than coming up with the perfect technology for the home market.

If you could sum up both SpaceX and Tesla in one phrase, it would probably be "perfect is the enemy of the good." You're much better off taking something that's good enough that you can get right now than you are trying to invent the perfect technology.
