||1: Speedy discharge is not the only advantage supercapacitors bring. They can be recharged more quickly, too. That makes them particularly useful in regenerative-braking systems, since they are able to absorb more of the electricity that is produced as a vehicle slows down. ||2: They can, though, store only a fraction of the amount of energy which a battery stuffs away. They therefore soon run out of puff. ||3: Because of this, engineers have been trying for a while to hybridise the best bits of a supercapacitor with the most useful features of a battery, to make a storage device with both speed and endurance. They are now having some success. ||4: Indeed, NAWATechnologies, near Aix-en-Provence, France, claims its supercapacitor-like battery could more than double the range of an electric car, allowing it to be driven for 1,000km on a single charge. This new device could also, NAWA says, be recharged to 80% of its capacity in as little as five minutes.

||1:快速放电并不是超级电容器的唯一特长，它还能够快速充电，这一点使得它们在生制动系统中尤其出色，因为它们能够吸收汽车减速时产生的更多电力。||2:不过，它们能够储存的能量只有电池的一小部分，过不了多久便会气喘吁吁。||3:于是乎，工程师们一段时间以来一直在尝试将超级电容器的最佳性能和电池最有用的特性相结合，制造一种兼具速度和持久性的存储设备。他们目前取得了一些成功。||4:其实，位于法国艾克斯-普罗旺斯附近的NAWATechnologies公司声称，其类似于超级电容的电池可以使电动汽车的续航里程增加一倍以上，充电一次可行驶1000公里，另外这种新设备还可以在五分钟内充80%的电量。
