Volvo Car Group has announced their development of what they term, “A revolutionary concept for lightweight structural energy storage components that could improve the energy usage of future electrified vehicles.” Using carbon fiber and other composite materials to make batteries and supercapacitors within structural panels, Volvo hopes to offer “lighter energy storage that requires less space in the car, cost effective structure options and is eco-friendly.” This blog reported on earlier efforts by Dr. Emile Greenhalgh at Imperial College in London, working on creating energy storage with simple carbon-fiber/fiberglass/carbon-fiber sandwiches as an academic lead partner with Volvo. His work is directed toward creating structural supercapacitors, while efforts at Volvo in Sweden, led by Per-Ivar Sellergren and working with his nearly two-decade-old patents, are aimed toward crafting lightweight batteries to replace metal structures. Funded as part of a European Union research project, and concerned with improving energy storage, the effort has Volvo as its only car manufacturer. The car maker’s project …
Battery Prices and Lithium Futures
EV World has a weekly email update to which your editor subscribes. Because they provide a collection of articles and opinions from different sources, one often comes away questioning trends and even facts – or sometimes the meaning of it all. This week, an article referenced from Green Car Reports says that EV batteries may already have fallen to $250 per kilowatt hour. This would be a godsend for sales of battery-powered cars, because sticker prices would drop sharply. The article quotes Wolfgang Bernhart, a partner at Rolan Berger Strategy Consultants, that battery prices are already much lower than previous predictions would have indicated, possibly as low as $250 per kilowatt hour. His analysis credited economies of scale for this drop, which is based on 2015 demand. This paradoxical approach notes that battery manufacturers must begin planning production now for 2015 EVs, with prices quoted to those manufacturers based on that future demand. Such prices would be an optimistic five …
