Michael Kanellos of GreenTechMedia.com reports on the price of batteries in the Nissan Leaf electric vehicle.
Right now, lithium ion batteries for cars cost around $900 per kilowatt hour. The Leaf has a 24 kilowatt hour battery. Under that math, a Leaf battery--if it were more like a regular electric car battery--should cost around $21,000. A battery is a third of the price of an electric car. Thus, the Leaf, if it had an ordinary battery, should cost closer to $60,000.
However, if Nissan has dropped the price to $500 a kilowatt hour, and rumors say the company is already close to that, the battery pack only costs about $12,000.
Regular readers will recall that in January Boston Consulting Group estimated current battery costs at $1100 to $1200 per kwh. BCG didn't sound optimistic about getting the costs down to $250 per kwh by 2020. But Nissan and NEC, with a lithium manganese chemistry, might be making fastes progress in cutting costs.
The Nissan Leaf has a US price before tax credits of $32,780. Will Nissan initially take a loss on the Leaf? Do Nissan and NEC have a battery cost advantage over GM, Ford, and other car makers who are bringing out PHEV and EV cars in 2010, 2011, and 2012?
Our ability to cut our reliance on oil depends very heavily on the development of technologies for powering cars that do not rely on oil. So far biomass energy approaches aren't viable substitutes. Corn ethanol has too low an Energy Return On Energy Invested (EROEI), it doesn't scale due to lack of farm land, and serves mainly to enrich corn farmers. Hydrogen has far too many serious problems. Advances in battery technology look to have the best prospects for cutting dependence on oil.
