A California teen has attracted the attention of tech giants Google for her potentially revolutionary invention which charges a phone in 20 seconds flat.
      美國加州的一個少女由於她革命性的潛在發明而吸引了科技巨頭google的關注,這項發明有可能會讓手機在20秒內充滿電。

The super-fast charging device has been dubbed a supercapacitor by 18-year-old Esha Khare, of Saratoga - as she took home $50,000 from the Intel International Science and Engineering Fair, which took place in Phoenix this week.
      發明這種快速手機充電器的是來自美國薩拉托加的18歲少女 Esha Khare ,她將其稱為超級電容器。本周,她因為此項發明在費城獲得了由英特爾國際科學工程大獎賽授予的5萬美金獎勵。

The device will make waiting hours for a phone to charge a thing of the past and the gizmo packs more energy into a smaller space than traditional phone batteries and holds the charge for longer.
      該設備有可能讓數小時的手機充電成為過去,並且這項發明比傳統手機電池能夠在更小空間儲存更多的電量,並使被充電的設備能使用更長時間。

So far, Khare has only used her supercapacitor to power a light-emitting diode or LED - but she sees a bright future that one day will see her invention powering cellphones, cars and any gadget that requires a rechargeable battery.
      到目前為止,Khare 只有嘗試過用超級電容器給發光二極體充電—但她的這項發明前景非常光明:有一天這一發明將可以用於手機、汽車或任何使用充電式電池的設備。

Heading to Harvard, Khare told CBS San Francisco that this is only the start and that she will 'be setting the world on fire' from here. 'My cellphone battery always dies,' she told NBC News when asked what inspired her to work on the energy-storage technology.
      即將前往哈佛大學就讀的 Khare 告訴哥倫比亞廣播公司,這只是開始,而且她將從此“令全世界瘋狂”。  “我的手機電源總是用光,” 當被問及什麼激發了她從事儲能科技研究時,她這樣告訴全美廣播公司。

Specializing in nanochemistry allowed Khare to reduve the size of her invention. ' Really working at the nanoscale to make significant advances in many different fields.' The supercapacitor is flexible and tiny, and is able to handle 10,000 recharge cycles, more than normal batteries by a factor of 10.
      納米化學系出身的 Khare 在這一發明上充分運用了納米技術。“使用納米技術可以在許多領域做出巨大成就。” 這種超級電容器非常靈活,體型迷你,且能夠處理1萬個充電回數,比普通電池多了10倍。

How an 18-year-old girl has managed to figure out something that multi-national corporations have not has led to her being flooded with offers for her amazing leap forward. Google have been in contact with Khare to explore how she plans to change the makeup of cell phone battery life.
      一個18歲的女孩如何能想出這麼多跨國公司都沒想到的東西,她的神奇發明已經吸引了很多公司找上門。目前google已與卡瑞取得聯繫,試圖探索她對於新發明改變手機電池壽命的計畫。

supercapacitor 超級電容器
      又叫雙電層電容器(Electrical Doule-Layer Capacitor)、黃金電容、法拉電容。它與普通電容的最大區別是它是一種電化學的物理部件,但本身並不進行化學反應,超級電容的儲電量特別大,達到法拉級的電容量。
      怎麼樣增加兩極板的面積呢?超級電容通過注入電解質來儲能,電解質在電極的作用下,電極表面電荷將吸引周圍電解質溶液中的異性離子,使這些離子附於電極表面上形成雙電荷層, 構成雙電層電容。由於兩電荷層的距離非常小(一般 0.5mm 以下),再加之採用特殊電極結構,使電極表面積成萬倍的增加,從而產生極大的電容量。
Supercapacitor (SC), formerly called electric double-layer capacitor (EDLC), is the generic term for a family of electrochemical capacitors. Supercapacitors, sometimes also called ultracapacitors, don't have a conventional solid dielectric.
