您是否不祝愿您的笔记本，音乐球员，并且数字照相机所有能数秒被充电而不是严厉小时？ 未来为呼喊“呀!”的那些您看起来伟大。
M.I.T研究员显露他们在可能使快速充电和持久可再充电电池成为可能的突破电池技术工作。 但而不是开发新的事，他们转向了改进技术从过去! 并且它结果是 电容器被发明大约300年前。
问题与电容器是他们的大小。 存储容量是相对电容器的电极的表面，比相似地大小的当前电池使当前电容器25次较不可胜任。
300年后，今天的M.I.T研究员通过雇用最后解决了这个问题 nanotechnology. 通过盖电极与 nanotubes 那比人发，电容器可能现在存放许多时间更多能量是30,000次稀释剂。
或许“可能充电它许多，许多次 成千上万的次和…它可能是充电非常迅速，数秒而不是几小时事情”，成员说Joel Schindall， M.I.T研究小组的。
这是好消息为环境保护者，因为这意味将显著减少被配置的电池的数量。
Schindall在市场上盼望一个原型在几个月被完成和希望看电池在少于五年。
我确定地盼望此，是？
[…] M.I.T researchers have revealed that they have been working on a breakthrough battery technology that could make fast-charging and long-lasting rechargeable batteries possible. But instead of developing something new, they turned to improving a technology from the past! And it turns out to be the capacitor, which was invented some 300 years ago. […]
[…] Fortunately, researchers have found a solution to this problem from a 300-year-old invention, the capacitor. The amount of charge or power that a capacitor can keep is limited to its surface area, and it would require a really really large capacitor to hold enough charge to power a device. You’d probably need a capacitor as large as a car to power your laptop for a couple of hours. The problem with capacitors is their size. The storage capacity is relative to the surface area of the capacitor’s electrodes, which makes current capacitors 25 times less capable than similarly sized current batteries. […]

Imagine how easy it would be to steal and sell energy with one of these. You could load up a car and head by all the open outlets you can find, then suck your battery full then make the meter turn backwards at your house.

LMAO, i love it how the first comment is about how you could steal electricity, good idea though.
can’t wait to see these batteries in action should be revolutionary =)

This kind of technology would absolutely revolutionize everything overnight. Imagine electric cars that would not need gasoline and could charge up in an hour vs 8 to 24 hours. I sincerely hope this comes to fruition because it could really have the potential to change the world. The global community absolutely NEEDS this.

But capacitors dont release charge at a slow and steady rate like a battery which is why they are not used in the same way, its not the amount of energy thats ever been the problem, so i cant see how this helps.

You know, I think those “morons” at MIT have probably thought about that quick release problem (hence the announcement of the technology touting these capacitors as batteries). Using just a simple resistor will slow the discharge of a capacitor…. I’m stoked for this, I just don’t think certain oily goons are gonna let this get out any time soon.
