The Kokam battery in question is a large format primatic lithium ion polymer affair with a notable energy density of about 180 Wh/kg. A robust cycle life, it can be completely charged and discharged over 1,500 times before dipping below 80 percent of original energy capacity. Of course, when it comes to batteries, price is one of the most important factors and Kokam America is truly competitive here. Their CEO, Don Nissanka, says their cells are currently in the $750/kWh range and they expect to significantly improve on that point, he says, "Going into the auto industry, we have to keep below $0.50/Wh [$500/kWh] and we believe we can get there." We expect that if they do, they should have no shortage of customers in the future.
