I think we'll see the 'ownership' issue disappear over time.
In the aircraft market, airlines no-longer own their engines, they buy 'thrust' through programmes such as Rolls-Royce's 'power by the hour'. I see this type of model moving into the consumer area increasingly. Why own a battery when you can pay a small monthly fee for provision of energy?
I'm not sure about US, but in UK we're already seeing people essentially give up ownership of their cars and move to a constant finance model with Personal Contract Purchase (PCP) payments. They pretty much never own the car, instead they have it for 3 years and hand it back in return for a new car and new PCP. This is changing the way that many people think about car ownership, it's only a small leap to move to a system where you pay for your car through usage and the service company ensures that you have a vehicle with a charged battery when you need it.
We're already seeing it in the music market, people are happy to pay for a music service rather than own CDs.
