Description

EP.28 零重量電池,讓車子依舊馬力滿檔! 粉絲專頁:https://www.facebook.com/scientists543/ 我們一般認為電池越大顆,它的電力會很強,用了三天三夜依舊電力足夠,所以汽車要長途旅程,照理來講,它的油箱要很大;電動車的電池也要很大顆,供應有足夠的電力! 但是,大顆電池,它的體積大又重,車子也要變得更大更重、耗電變快,有可能續航力變不好… 那就把電池變成零重量吧! 瑞典 Chalmers 科技大學的Leif Asp教授團隊開發了一種新電池,他們利用碳纖維作為負極、表面包覆磷酸鋰鐵的鋁箔為正極,中間以玻璃纖維作為絕緣,並持續改善,預估能量密度可達到 75 Wh/kg以及75 GPa 的強度,這種材料也比鋼材更輕! 本集以Leif Asp教授團隊之研究,如何讓電池零重量! -- Hosting provided by SoundOn
