Article contradicts itself and reality to make lithium ion seem more expensive. First it says that batteries typically cost $500 / kWh, so that a battery for a "small electric car can cost around $10,000". (As an aside, Nissan will sell me a replacement battery for my LEAF for $5499. [1]) This is $229.13 / kWh, because my LEAF has a 24 kWh battery. Then it says Tesla is selling the 10kWh PowerWall for $3500, which of course is $350 / kWh. Sloppy reporting. I expect better from the Economist. 1 - http://www.greencarreports.com/news/1092983_nissan-leaf-battery-cost-5500-for-replacement-with-heat-resistant-chemistry http://www.greencarreports.com/news/1092983_nissan-leaf-batt...
