They would spend the money to scale up to production of a new machine that makes a cell every two to ten seconds. This machine, to be available for sale in two years, would be for stationary electric batteries—used to power businesses, neighborhoods and utilities, rather than cars. The machine would have a capacity of 79 megawatt-hours a year and produce any kind of lithium-ion battery for a cost of about $160 per kilowatt-hour. By 2020, Chiang says, that will be down to about $85, 30% below where conventional lithium-ion batteries—whose cost is also dropping—may be by then. But most importantly, the machine would be priced at about $11 million. Hence, the startup cost of getting into lithium-ion battery manufacturing would plummet. “It’s so far out of the paradigm, you just don’t believe it,” said Wilder.
