Count Lux Research among the pessimists when it comes to the costs of lithium-ion battery packs.
Lithium-ion battery costs will fall to about $400 per kilowatt hour by the end of the decade, more than double the $150 per kilowatt hour the U.S. Advanced Battery Consortium says will be required for battery-electric vehicles to be affordable to most of the car-buying public. So says a new report from Lux Research.
Not enough EV batteries will be made to create the economies of scale required for a substantial cost reduction, while few technologies aside from the current lithium-ion process, such as Li-air and solid-state batteries, will be developed in time to make much of an impact by 2020, according to the report.
The report is the latest to weigh in on how far battery costs will fall as automakers hope to ramp up on EV production to meet progressively more stringent greenhouse-gas emissions requirements both in the U.S. and abroad. Green-technology firm Pike Research said last month that lithium-ion battery costs may fall by about a third to about $523 per kilowatt hour by 2017, while global revenue for transportation-oriented lithium-ion batteries will jump to $14.6 billion in 2017 from about $2 billion in 2011.
Estimates of battery costs have varied as automakers and tech analysts have looked into ways to make them cheaper. The Nissan Leaf EV's battery pack has been reported to be as cheap as $375 per kilowatt hour, while Tesla Motors CEO Elon Musk said last month that battery costs may fall to less than $200 per kilowatt hour "in the not-too-distant future."
