新一代离子电池容量可达锂电池11倍？ - 电源技术 - 电子工

刚刚看到了一篇报道，说新一代离子电池容量可达锂电池11倍。后来查了一下英文资料，发现根本不是那么回事，只是说一些研究人员争取到了美国能源部的项目资金用于进一步的研究工作，并没有研制出真正的电池（the company still apparently doesn't have an actual battery to back up its claims just yet）。

以下是CNBeta中文报道和Engadget英文报道。

新一代离子电池容量可达锂电池11倍
来源:cnbeta

　　Fluidic Energy研究人员今天宣布已经研究出一种新的金属空气离子液体电池，利用相对高效率的储能锌通过盐离子液体进行能量存储，让电池效率更长且更稳定。

　　研究人员估计他们可以在1公斤重量下提高电池效率900〜1600瓦小时，这是普通笔记本电脑锂离子电池容量的11倍，是目前17英寸的MacBook Pro内置的1.25磅电池的5倍。

　　他们的研发工作拥有来自政府的资金，因为汽车是一种特殊的重点和政府拨款的理由，他们可以延长电动汽车行走400-500英里。

　　不过挑战依然存在，主要问题是预期的性能能否完全达到以及材料的廉价程度。

Fluidic Energy promises better, cheaper metal-air batteries, wins DoE grant

It's not the only company working on metal-air batteries, but Scottsdale, Arizona-based Fluidic Energy may be in a better position to deliver on its promises than most, as it's just managed to snag a $5.13 million research grant from the US Department of Energy to further develop the "breakthrough" technology. While that word's thrown around quite a bit these, in the case, it may actually live up to the hype, considering that breakthrough in question would be a battery that's able to deliver eleven times the energy density of the best lithium-ion batteries for less than one-third of the cost. The key to that, it seems, is the battery's use of an ionic liquid as its electrolyte, which is described as a "wonder fluid" since it's able to last significantly longer than other fluids because drying out isn't a problem, and because it brings with it a significant boost in energy density. Of course, the company still apparently doesn't have an actual battery to back up its claims just yet, and it's not making any promises about when it might deliver one either.
