With Tesla’s $5.5 billion “gigafactory” already producing cells for its line of cars and its “Powerwall” home energy storage systems, it now seems like a tenuous, toe-dipping approach with Volkswagen announcing its own battery plans. VW may invest up to $15.5 billion according to Tech News, the outlet projecting the highest number. Others with less money but promising technologies are also betting on better batteries. Tesla Gigafactory Grand Opening – More to Come With only 14 percent of its total area completed, the Tesla Gigafactory on Electric Avenue (what else?) near Sparks, Nevada, is already up and running, producing Tesla’s Powerwall and Powerpack battery systems. According to Teslarati.com, “Elon Musk told investors at the 4th quarter earnings call earlier this month… those products are already profitable and are expected to become more so as volume increases.” Other projections anticipate that the Gigafactory will “be net zero and have no carbon emissions,” “net zero meaning that it will create more electricity …
First Seeo, Now Sakti3
Bosch’s acquisition of Seeo Inc. is followed within seven weeks by news that an innovator in another area has acquired a battery developer. Electric-vehiclenews.com announced that “Dyson, the U.K. company famous for its bagless vacuum cleaners, has acquired Michigan-based solid-state battery startup Sakti3 for $90 million and announced plans to build an important $1 billion battery factory to mass produce the next generation battery technology.” The report noted this was the second recent purchase of a promising start-up company by a larger, richer firm. Bosch acquired Seeo Inc. to benefit from its solid-state technology, which like most solid-state batteries would, among other benefits, reduce or eliminate fire hazards – something brought to the fore by recent FAA rulings on shipping of lithium batteries. Sakti3 has announced a solid-state cell with 400 Watt-hours per kilogram energy density, roughly twice that of most competitors, including Tesla’s – reputed to be around 230 Wh/kg. Although Sakti3 founder and CEO Ann Marie Sastry joins Dyson as …
Bosch Doubles Down on Solid-State Batteries
Bosch, the German electronics giant, is making a strong showing at the Frankfurt Motor Show (IAA), and showing off its solid-state Li-ion battery technology. It recently acquired Seeo, Inc., an American startup that has been developing such a battery for several years, and will add Seeo’s research to its own expertise and exclusive patents. Encouragingly, the company says it will be able to double the energy density of Li-ion batteries while cutting prices by half. Perhaps discouragingly, Bosch says this will take until 2020 to bring to production. Green Car Congress quotes Dr. Volkmar Denner, chairman of the board of management for Robert Bosch GmbH, claiming a breakthrough. “Bosch is using its knowledge and considerable financial resources to achieve a breakthrough for electromobility. Solid-state cells could be a breakthrough technology. Disruptive start-up technology is meeting the broad systems knowledge and financial resources of a multinational company.” Coupling the acquisition with its 30 production projects “related to electromobility,” Bosch has been …
Lithium Sulfur Batteries – Energy Storage at New Heights
Last year, Oak Ridge National Laboratory (ORNL) announced that researchers had “successfully demonstrated that lithium-sulfur battery technology can indeed outdo lithium-ion on several fronts.” Theoretically, lithium-sulfur batteries could be four times as energy dense as today’s lithium-ion batteries, but that promise had yet to be demonstrated. ORNL took initial steps toward that goal, and within the last few months researchers at Vanderbilt University have shown a strong lead in forming lithium-sulfur batteries with commercial potential. Echoing work done at Sakti3, ORNL researchers demonstrated an all-solid-state lithium-sulfur cell, addressing flammability issues shared by batteries with solid electrolytes. Using lithium polysulfidophosphates (LPSPs) in the cathode, and which have ionic conductivities eight times higher than that of lithium sulfide (Li2S) the team coupled that with a lithium anode to create “an energy-dense, all solid battery.” Energy density was a noteworthy 1,200 mili-Amp-hours per gram, about 7 to 8.5 times that of conventional lithium batteries. A number of blogs repeated the slightly overheated lines …
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 …
