The main impediment to mass electric-car adoption is price, and the driving force behind that is the cost of lithium-ion battery cells. The performance of those cells improves at about 7 percent a year, give or take: Either the same cell costs 7 percent less after a year, or a carmaker gets 7 percent more energy capacity for the same price. Those... Silicon anodes to boost lithium-ion battery capacity within a few years
