Poor battery life is the number one complaint when it comes to smartphones and laptops. As a wireless society, having to tether ourselves down to power up our gadgets seems more and more a nuisance. And while researchers are looking into wireless charging, if batteries were better we would have to worry less.
續航器蓄電池年限短是智妙手機和條記本PC電腦的首要麻煩。在無限數字的市場里,給配置續航器時用繩子束厄狹小住客觀事物恍若越發反感。不言而喻研究討論部門經理時未尋找無限數字續航器的方式方法,但若是有效果更好的續航器蓄電池科學研究的耽憂也是可以夠耽誤了。
Now, a new technology promises just that. Researchers from the University of California, Irvine, have invented a nanowire-based battery that can be recharged hundreds of thousands of times, a significant leap towards a battery that doesn’t require replacing.
這時候一家新的技術的就也能保持。存在加利福尼亞社會歐文分校的研究普通員工發了然本身納米技術線動力動力電板,該動力動力電板也能充電樁幾十塊萬次而不改換,這時動力動力電板成材的一家較著崩騰。
Nanowires possess several ideal characteristics for electric storage and transmission. They are highly conductive and thousands of times thinner than a human hair, which means they can be arranged to provide a large surface area for electron transfer. Unfortunately, nanowires are usually very fragile and don’t do well after repeated charging and discharging.
微米線必備電隨意調節和無線傳輸的多少錢人生理想顯著特點。同旁內角必備高導電性以及比全人類的頭發長細好幾千倍,這意喻著同旁內角是可以供求平衡個長久集團長相東北部供電設備子轉讓。可伶的是,微米線本身多少常儒弱的,以及會在頻煩充充放后的降低機器。
The researchers, whose findings are published in the American Chemical Society’s Energy Letters, have coated gold nanowires in manganese dioxide and cocooned them in a Plexiglas-like gel. This combination keeps all the properties of the nanowires’ intact and makes them resistant to fractures.
專題會者給金質奈米級線包一個多層殼,并齊樹酯安全玻璃這種的凝露薄層進行快遞,這一專題會成效下發在《美國的催化學會·沖力微波通信》上。廣泛性聯系使奈米級線的任何卡能堅持什么增強,并使其耐折損。
Mya Le Thai, the lead study author, has charged and discharged the battery up to 200,000 times without breaking the nanowires and without loss of capacity.
這種研討會的表率人妙萊泰給手機充電關閉程序了200000次手機充電和蓄電池放電的操作,而奈米線并不損傷,存儲容量就要缺失。
“Mya was playing around, and she coated this whole thing with a very thin gel layer and started to cycle it,” said senior author Reginald Penner, chair of UCI’s chemistry department, in a statement. “She discovered that just by using this gel, she could cycle it hundreds of thousands of times without losing any capacity.”
“妙萊泰不住在玩,她給金質微米線包一個多層殼并起頭給微米線充尖端擊穿,” 加利福尼亞上大學歐文分校化工系室主任,專家型專家雷金納德在第二份聲明函上說。“她發明的故事,只需用這一類膠,她就也可以充尖端擊穿成千盈百次而不落下某些數量。”
“That was crazy,” he added, “because these things typically die in dramatic fashion after 5,000 or 6,000 or 7,000 cycles at most.”
“這太驕橫了,”他多補說,“隨著數量最多顛末5000、6000或7000個(快速充電)期,哪些東西硬性地方較下落空影響。”
The researchers believe that the combination of the PMMA (plexiglass-like) gel electrolyte and the magnesium oxide gives flexibility and structure to the nanowires, preventing cracking and thus extending their operational life.
專題討論財務人員誤以為,PMMA(硅酸窗戶玻璃等)凝露鈦電極質和氧化的鎂的取得聯系物為nm線市場均衡了能規避其裂紋的矯捷性和布置圖,才能耽擱了其使用時間。
“The coated electrode holds its shape much better, making it a more reliable option,” Thai said. “This research proves that a nanowire-based battery electrode can have a long lifetime and that we can make these kinds of batteries a reality.”
“被耐磨涂層的電極材料片保持良好其實質就樣式的才會較強眾多,是以是更靠經得住的首選項,” 妙萊泰說。“此項研討會斷定,nm線為其實的電瓶電極材料片會有好長的生命周期,咋們會使這種實例的電瓶的成為實計。”
