The demand for lithium-ion automobile batteries is projected to increase from 2.4 gigawatt hours (GWh) this year to 18 GWh by 2013 - a seven fold increase. The rapid increase in lithium-ion battery production -- 20 new plants are under construction -- is expected to drive the cost of these batteries down from $800-1000/kWh today to the vicinity of $350 by the end of the decade.
