說到石墨烯電池，大家都知道他是現在電池(chi)界的(de)(de)翹楚，是石油工業的(de)(de)終結(jie)，全球變暖的(de)(de)解決方(fang)案(an)，將為數百萬人提供食(shi)物和衣物，治愈(yu)疾病，是太空電梯的(de)(de)基礎，這將使(shi)人類能夠冒險進入銀河系(xi)。但(dan)是，圍繞石墨烯還是有一些炒作。今(jin)天(tian)我們來(lai)聊(liao)聊(liao)石墨烯電池(chi)的(de)(de)那(nei)些事吧(ba)！

隨著營銷的大肆宣傳，營銷使得產品變得可疑。最新的是HobbyKing的石墨烯電池。根據文獻，這些用于RC平面和無人機的鋰聚合物電池組’利用(yong)電池(chi)(chi)(chi)結構中的(de)碳形成單層石(shi)墨(mo)烯，石(shi)墨(mo)烯顆粒用(yong)于高密度化合物(wu)，與傳統聚合物(wu)鋰電池(chi)(chi)(chi)相比，電子流動的(de)阻力更(geng)小(xiao)的(de)電池(chi)(chi)(chi)技(ji)術，“這些電池(chi)(chi)(chi)也采用(yong)黑(hei)色(se)(se)收縮管(guan)包裝，并配有黑(hei)色(se)(se)電池(chi)(chi)(chi)連接器，使(shi)其(qi)看起來比非石(shi)墨(mo)烯相當。僅(jin)此一項(xiang)就可以(yi)使(shi)任何遙控飛機的(de)最高速度增(zeng)加至少(shao)5英(ying)里每小(xiao)時。

在(zai)(zai)過去幾年(nian)中(zhong)，石(shi)(shi)(shi)墨烯(xi)最(zui)有趣的(de)潛在(zai)(zai)應用之(zhi)一(yi)是(shi)(shi)(shi)儲能(neng)。石(shi)(shi)(shi)墨烯(xi)超級(ji)(ji)電(dian)(dian)(dian)(dian)(dian)(dian)容器(qi)(qi)即將(jiang)出現(xian)，它具有令人(ren)難以置信的(de)電(dian)(dian)(dian)(dian)(dian)(dian)荷密度和快速充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)時間(jian)。希(xi)望在(zai)(zai)十年(nian)或兩年(nian)內，我們可能(neng)會看到電(dian)(dian)(dian)(dian)(dian)(dian)動汽車不(bu)是(shi)(shi)(shi)由傳統(tong)的(de)鋰電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)供電(dian)(dian)(dian)(dian)(dian)(dian)，而(er)是(shi)(shi)(shi)石(shi)(shi)(shi)墨烯(xi)超級(ji)(ji)電(dian)(dian)(dian)(dian)(dian)(dian)容器(qi)(qi)。他(ta)們將(jiang)能(neng)夠在(zai)(zai)幾分(fen)鐘內充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)，并(bing)進一(yi)步推動，讓(rang)世界(jie)從化石(shi)(shi)(shi)燃料經濟(ji)轉型。世界(jie)和平在(zai)(zai)此(ci)之(zhi)后大約兩周開始。然而(er)，現(xian)在(zai)(zai)沒(mei)有人(ren)會想到石(shi)(shi)(shi)墨烯(xi)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)會出現(xian)，特別是(shi)(shi)(shi)那些最(zui)大市場正在(zai)(zai)為自己(ji)制(zhi)造(zao)四軸飛(fei)機的(de)人(ren)銷(xiao)售零件的(de)公司(si)。這些電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)如何(he)支撐(cheng)？根據第一(yi)次(ci)獨立評論，它是(shi)(shi)(shi)一(yi)個很好的(de)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)，但石(shi)(shi)(shi)墨烯(xi)主要(yao)是(shi)(shi)(shi)在(zai)(zai)標簽上。

RCgroups論壇上對電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)首次(ci)生(sheng)(sheng)產(chan)運(yun)行進行了(le)(le)一(yi)(yi)些(xie)(xie)(xie)測試，實際(ji)上它(ta)們非(fei)常(chang)好(hao)(hao)(hao)。它(ta)們經歷(li)了(le)(le)很多充電(dian)(dian)(dian)(dian)(dian)周期，而(er)(er)(er)且包(bao)裝(zhuang) – 對于將要發生(sheng)(sheng)碰(peng)撞的(de)事(shi)情非(fei)常(chang)重(zhong)(zhong)要 – 非(fei)常(chang)好(hao)(hao)(hao)。這(zhe)些(xie)(xie)(xie)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)實際(ji)上是(shi)(shi)否在化學中使用石墨(mo)烯？這(zhe)是(shi)(shi)一(yi)(yi)個懸而(er)(er)(er)未決的(de)問題，不是(shi)(shi)嗎(ma)？公平地(di)說(shuo)，在HobbyKing正式發布(bu)之前發送給評(ping)論者的(de)石墨(mo)烯電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)表現(xian)非(fei)常(chang)好(hao)(hao)(hao)。然而(er)(er)(er)，為了(le)(le)公平起見，這(zhe)些(xie)(xie)(xie)絕不是(shi)(shi)庫存(cun)(cun)’石墨(mo)烯’電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)組。審稿人(ren)(ren)可能(neng)不會這(zhe)樣，但這(zhe)些(xie)(xie)(xie)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)組是(shi)(shi)HobbyKing可以生(sheng)(sheng)產(chan)的(de)最好(hao)(hao)(hao)的(de)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)組，并不一(yi)(yi)定代表我們可以購買的(de)產(chan)品。同樣令人(ren)(ren)懷(huai)疑的(de)是(shi)(shi)，這(zhe)些(xie)(xie)(xie)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)在其結構中使用了(le)(le)大量的(de)石墨(mo)烯。根(gen)據(ju)現(xian)有研(yan)究，石墨(mo)烯增加(jia)了(le)(le)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)功率和能(neng)量密度(du)。新型石墨(mo)烯電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)儲(chu)存(cun)(cun)的(de)能(neng)量與多年來一(yi)(yi)直存(cun)(cun)在的(de)納米(mi)技術(shu)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)相當，但重(zhong)(zhong)量卻要大得多。這(zhe)可能(neng)是(shi)(shi)由于電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)組本身的(de)結構不同，但石墨(mo)烯電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)應該更(geng)輕更(geng)小(xiao)，不重(zhong)(zhong)20克，厚(hou)5毫(hao)米(mi)。

在RC世界(jie)中(zhong)，HobbyKing被稱為(wei)“足(zu)夠(gou)好(hao)”。這不是(shi)你能(neng)得到的(de)最好(hao)的(de)東西，但它很便(bian)宜。它是(shi)RC世界(jie)的(de)沃(wo)爾瑪，而沃(wo)爾瑪并沒有引入據(ju)稱拯救(jiu)地球的(de)尖(jian)端技術。
