一场电池革命可能即将发生：引起广泛质疑的EEStor超级电容电池现与洛克希德•马丁公司签定授权协议. 洛克希德—马丁公司目前是美国第一大国防承包商，创建于1913年，1932年改称洛克希德飞机股份有限公司，1938年改为现名。 这下还怀疑EEStor超级电容电池的人该减少了吧.看来他们声称的超级电容:充电5分钟,可储能52.22KWH,供14匹马力的电动汽车,以每小时96公里速度使用5小时,行驶480公里。可能不是吹牛.一场电池革命可能即将发生. EEStor超级电容电池的原理很简单,即传统的法拉第电容,两片电极夹电介质,高中的物理知识,但他们只不过把电极厚度做到1µm,电介质的介电常数做到19861,耐压做到557V/µm,厚度做到9.81µm,比能量密度达402WH/公斤(10 times the energy density of lead acid batteries at 1/10th the weight and volume)。根据E=1/2CV2和C=εKA/t不难验证他们这个结果的可信度. 他们被怀疑的地方主要是随着电压的升高, 介电常数剧减, 介电常数在他们声称的3500V下不可能还保持那么大,还有是电介质耐压不可能那么高,容易被击穿和容易漏电。多数的专家教授持否定态度，下面是有关讨论的链接： http://www.technologyreview.com/Biztech/18086/ http://tyler.blogware.com/blog/_archives/2007/11/1/3328442.html http://www.rexresearch.com/weir/weir.htm http://www.gm-volt.com/2008/01/1 ... eement-with-eestor/ 本人近半年来一直跟踪EEStor超级电容的发展，国内除了一些有关EEStor公司的消息报导外，在学术界还未引起关注，本人还未见到国内有关把传统的法拉第电容作为储能电池方面的研究报道。大部分都跟风搞燃料电池，电化学（双电层）超级电容和准法拉第超级电容。上海的超级电容公车示范线恐怕是电化学超级电容应用最牛的，但与EEStor公司的法拉第超级电容一比差远了，电化学超级电容的比能量密度要达到402WH/公斤几乎是不可能的。眼看这种只应用高中的物理原理的知识产权又要归美国人了，EEStor公司已公布2个专利，另外17个专利在申请中。信息革命的电脑芯片和软件我们已经落后了，能源革命的原创权我们有可能又丢了。我们的科研经费每年都在增加，而创新能力却在下降，科技界缺少主见，论文在国外发表才牛，知识流失严重。其实国内搞钛酸钡介电材料研究的很多，有人能把介电常数做到30万，可惜这篇文在国外发表，国内看不到。国内没有人能想到用这么大的介电常数搞法拉第超级电容，而被美国人了先想到了，据说发明人WEIR，RICHARD，D. 曾经在IBM搞硬盘出身。作为中国知识分子的一员，深感悲哀，现在有多少人还能在科研中追求真理而看淡名利作为自觉的世界观。 迅速开展法拉第超级电容作为储能电池方面的研究刻不容缓，否则有可能步电脑芯片和软件的后尘，我们将失去许多原创权。本人昨天已向福建省科学技术厅提交了2008年重点项目“超级电容电池研制”，本项目需无机、有机、高分子聚合物、物理化学、陶瓷材料和电子物理等不同学科和专业的广泛合作，有在福建省科技信息综合业务系统注册的专家并对本项目有兴趣的可发邮件到zw63@hotmail.com,讨论合作事宜。 下面是有关EEStor超级电容电池现与洛克希德•马丁公司签定授权协议的最新报导： Lockheed Martin Signs Agreement With EESTOR For Energy Storage Solutions Electrical Energy Storage Units (EESU) by Staff Writers Dallas TX (SPX) Jan 10, 2008 Lockheed Martin has signed an exclusive international rights agreement to integrate and market Electrical Energy Storage Units (EESU) from EEStor for military and homeland security applications. Specific terms of the agreement were not disclosed. EEStor, based in Cedar Park, TX, is developing a ceramic battery chemistry that could provide 10 times the energy density of lead acid batteries at 1/10th the weight and volume. As envisioned, EESUs will be a fully "green" technology that will be half the price per stored watt-hour than traditional battery technologies. "Lockheed Martin has a wide range of innovative energy solutions for federal, state and regional energy applications," said Glenn Miller, vice president of Technical Operations and Applied Research at Lockheed Martin Missiles and Fire Control. "The EEStor energy storage technology provides potential solutions for the demanding requirements for energy in military and homeland defense applications." EESUs are planned as nontoxic, non-hazardous and non-explosive. Since the EESU design is based on ultra-capacitor architecture, it will allow for flexible packaging and rapid charge/discharge capabilities. EESUs will be ideally suited for a wide range of power management initiatives that could lead to energy independence for the Warfighter. "Lockheed Martin continues to focus on providing our Warfighters with new and innovative technologies that will make their jobs easier," said Lionel Liebman, manager of Program Development - Applied Research at Lockheed Martin Missiles and Fire Control. "Our ruggedized BattPack energy storage unit generated considerable interest at the Association of the United States Army Annual Meeting in October 2007 for its potential for fuel savings in vehicular silent watch applications. The potential of an even safer, smaller and more powerful EESU in BattPack would significantly enhance the Warfighter's capabilities." EESU qualification testing and mass production at EEStor's facility in Cedar Park is planned for late 2008. EEStor, Inc., of Cedar Park, TX, originally developed its solid-state EESU technology as a longer lasting, lighter, more powerful environmentally friendly electronic storage unit for a wide variety of applications. EEStor's vision also includes EESU facilitating the conversion of wind energy and photovoltaics into primary electrical energy providers and increasing the role of renewables for increasing energy production. Its CEO and president, Richard Weir, is also the inventor named on its EESU principal technology patent. Lockheed Martin Signs Agreement with EEStor Posted by Lyle under Battery , Research , Competitors Rate the post: Mostly, we talk about the Volt here, but relevant and related topics are often worth discussing. We have previously discussed a secretive Texas company called EEStor, who are reported to be working on a new type of ultracapacitor that can hold 10x the energy in 1/10th the weight of typical batteries, at a fraction of the cost. They have an agreement to produce caps for Zenn electric cars but to date have not shown any prototypes. This has led some to suspect EEStor as not having the technology they report. Today, however, Lockheed Martin, the major U.S. military equipment manufacturer has announced a partnership agreement with EEStor to develop energy applications. If these ultracaps can really deliver what they are projected to, they could offer a dramatic advantage for electric vehicles. To that end, I interviewed Lionel Liebman, manager of Program Development – Applied Research at Lockheed Martin Missiles and Fire Control. The entire interview can be seen by clicking below. Can you tell me what your announcement was today? Lockheed Martin and EEStor are working together to find areas for integrating their technology to a variety of power management platforms we’re working on. Is it a financial contract? We’re not taking any sort of ownership of EEStor. It is an exclusive rights agreement to allow us to market these technologies to a very limited number of potential customers including homeland security and the defense markets. Lockheed Martin builds fighter jets and military equipment? And missiles, rockets, ground equipment, vehicles, and systems sensors. Obviously everything that requires power to operate. Power is becoming a sticking point or burden to the warfighter and that’s one of the things were focused on is coming up with solutions that make the warfighter’s job easier and more efficient. Are you looking to develop portable energy storage for the battlefield? Yes there are opportunities not only to help in the area of relieving some of the dependence on fuel as energy. Also to increase the value of some of the renewable energy initiatives that are going on right now. Energy storage increase the value of these types of power generation technologies. EEStor’s technology can help in that area. What have you seen from EEStor in terms of their technology? We’ve visited their facility. We were very impressed. They are taking an approach that lends itself to a very quick ramp-up in production. We’ve seen a lot of their testing and efforts to measure the purity of the powders that they use, and the chemistry. Well be working with them very closely this year to develop prototypes in certain pursuits. Have you been able to evaluate any of their current prototypes? That’s an effort that’s ongoing. We’re really just getting started to integrate their technology into some of the efforts that we have going on here. That’s going to be something that we’re doing this year. So its a collaborative effort to build the prototypes then? That’s right. Do they have something that they’ve tested that you’ve seen which makes you want to work with them? We haven’t personally tested their prototypes yet. Its something that we’ll work on together this year. How does Lockheed marting feel about ultracaps and storage versus li-ion or NiMh batteries? Lockheed Martin doesn’t have a bias. One way or another its really just a function of what does the customer want. For certain applications being able to provide pulse power is really really important, in another its not so much really pulse power but continuous power. If you talk to the Army they are really interested in hybridized solutions. Suffice it to say that EEStor’s technology is a piece of some of these systems solutions that we come up with. We are a system integrator so we look at the EEStor technology as a building block or a tool in a toolbox to provide the best solutions for the soldier. Do you see the ultracap as a power solution or an energy solution? The EEStor chemistry and architecture lends itself to both types of applications. Its a scalable technology. In the situation where you are trying to store energy, transport it without discharge obviously thats very attractive in the utility grid load leveling (situation). If your talking about powering for example a high energy weapon that requires a short burst of energy a capacitor is a great approach to do that. Capacitors are in hybridized systems today for that reason. The chemistry is great purely form the view of battery technology but its also very attractive for some of these extremely high pulse power applications. Are you looking to use this technology in any vehicular type of application? We have a number of platforms that were working on. Our applied research group is primarily focused on land forces power management which involves several area including vehicular power. The needs of a consumer for a hybrid fuel-efficient car versus the need for a soldier in the battlefield are a bit different. The common theme there is what ca we do to make them more efficient ad battery technology is important for that. Are you confident that their technology will offer a greater amount of energy and power density than batteries? Yes, and at a fraction of the cost. Do their caps hold 10x the energy at 1/10th the weight of a lead acid battery? Yes. How does the the price of EEStor’s capacitors compare with Li-ion or NiMh batteries? It really depends on the chemistry, the volume, the packaging, the application. It is really application-specific. It’s going to be lower price. Were not just concerned about hardware cost. Really what were focused on is logistics. Especially the logistics footprint in theatre. That’s probably more important than material cost. And that one of the things that we think this technology can bring. Because it can be used for a variety of applications with a common architecture and chemistry. Its compact, its scalable and can be applied to a variety of applications. That obviously very attractive to a logistics community, to have more common components and that type of thing. Is there a production plan for 2008? Yes for EEStor. Their approach is when they start manufacturing these batteries, not just the cells, but also the package assembly, they will be in production. If you can get a visit to EEStor they’ll show you their process and everything they’ve got in place to support that. Assuming that everything comes together in terms of tests and qualifications and that sort of thing, they will be ready to ramp up very quickly, because of the nature if the architecture and scalability of what they are doing. Can you say anything about the use of EEStor’s technology in commercial vehicles? We are basically working with them exclusively and in the homeland security and defense department’s markets. The commercial vehicle market, that’s what EEStor will pursue. If their is a military application then we’re going to help them integrate their technology into those applications, but when it comes to commercial vehicles that’s EEStor’s responsibili [search]超级电容电池[/search] |

曾投资EEStor公司的加拿大ZENN公司 当日股票上涨22%

曾投资EEStor公司的加拿大ZENN公司 当日股票上涨22% ZENN stock leaps on Eestor's deal Lockheed Martin to use firm's battery products in several applications Jan 10, 2008 04:30 AM Tyler Hamilton Energy Reporter Local electric-vehicle maker ZENN Motor Co. got proof yesterday that its investment in advanced energy-storage company Eestor Inc. isn't a reckless gamble. Shares in Toronto-based ZENN rocketed more than 22 per cent yesterday after defence contractor Lockheed Martin Co. revealed an agreement to use Eestor's product for military and homeland security applications, including sensors, weapons systems, and vehicles that require power. Terms of the deal were not disclosed. Shares of ZENN, an early investor in Eestor, rose 82 cents to $4.48 on the TSX Venture Exchange. "We're focused primarily on battlefield applications," Lionel Liebman, manager of program development for Lockheed's missile and fire control division, told the Star. "We fully intend to work with Eestor this year to prototype and demonstrate this technology for soldiers in the field." Eestor, based in Cedar Park, Tex., is developing a ceramic battery or "ultracapacitor" that is expected to provide 10 times the energy punch as lead acid batteries at one-tenth the weight and for less than half the price. If the product is proven to work and is reliable, it could lead to the development of low-cost electric vehicles and large-scale systems for affordably storing solar and wind energy. Through its investments in the Texas start-up, ZENN – which stands for zero emissions, no noise – has the exclusive rights to use Eestor's storage system in small vehicles. Currently, ZENN's main business is manufacturing and selling low-speed electric vehicles that run on lead-acid batteries. Eestor has attracted as much skepticism as excitement. The Internet is filled with commentary from engineers and scientists who say the company's technology will never work as claimed. |
