Here's an idea to reduce the costs of lithium ion batteries: split it four ways. That was one proposal given by
Mitsubishi Heavy Industries senior executive vice president, Ichiro Fukue, at the 2010 Driving Sustainability conference in Reykjavík, Iceland this weekend. Here's how it might work.
When someone buys a new electric vehicle (EV), she would pay the battery manufacturer just 25 percent of the battery cost. After a few years, when the car is sold, the second buyer would pay the battery manufacturer the second 25 percent. Finally, when the EV is ready for the scrapyard, the power utility would buy the battery, paying the last 50 percent to the manufacturer. How this would all work in the real world was questioned by conference attendees, but it does give us a fresh new way to think about car ownership, doesn't it?
Most of Fukue's presentation, though, was about the lithium-ion battery market, which he said could reach $25 billion U.S. by 2020, and buses. The market will reach that high level even if (or maybe because of?) the price for li-ion batteries drops to $300-$400 per kWh in a few years, something Fukue predicted would happen.
