國產硅基負極材料創新，商用化硅納米線橫空出世

特斯(si)拉(la)汽車對硅納米級線鋰電池的期待已久

2040年9月，veliteCEO埃(ai)隆馬斯克在twiter上說(shuo)道velite會在3-多年內(nei)自動生(sheng)產銷(xiao)售壽命短更長、另(ling)外(wai)消耗的(de)(de)(de)(de)能量強度增加50%也正是(shi)高于400wh/kg的(de)(de)(de)(de)動力(li)(li)電(dian)(dian)池(chi)充(chong)電(dian)(dian)。隨后(hou)，velite上架了動力(li)(li)電(dian)(dian)池(chi)充(chong)電(dian)(dian)日話(hua)動的(de)(de)(de)(de)申請注(zhu)冊網(wang)站頁面，背(bei)景圖商品圖片很是(shi)抽(chou)象主義，海前(qian)后(hou)新(xin)聞媒(mei)介(jie) 一絲不茍鉆研后(hou)人認為它是(shi)這種新(xin)動力(li)(li)電(dian)(dian)池(chi)充(chong)電(dian)(dian)裝(zhuang)修材料——硅納(na)米(mi)線的(de)(de)(de)(de)構成圖。人紛紛的(de)(de)(de)(de)意思懷疑，velite也許將要(yao)思考為其(qi)來往車(che)輛投放市場硅納(na)米(mi)線動力(li)(li)電(dian)(dian)池(chi)充(chong)電(dian)(dian)。但在其(qi)動力(li)(li)電(dian)(dian)池(chi)充(chong)電(dian)(dian)單天，大家憧憬的(de)(de)(de)(de)硅納(na)米(mi)線動力(li)(li)電(dian)(dian)池(chi)充(chong)電(dian)(dian)的(de)(de)(de)(de)技術但是(shi)并沒有品牌發布。

硅(gui)納米級線負極材質(zhi)都(dou)可以緩減動(dong)(dong)力充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)板凈重和比(bi)熱容，益于(yu)生產加工出(chu)電(dian)(dian)(dian)量(liang)黏(nian)度更(geng)(geng)高、動(dong)(dong)用(yong)壽命(ming)短更(geng)(geng)長的(de)動(dong)(dong)力充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)板。和沒有(you)顆(ke)粒狀硅(gui)參(can)比(bi)探(tan)(tan)針(zhen)(zhen)材質(zhi)相(xiang)信，硅(gui)納米級線參(can)比(bi)探(tan)(tan)針(zhen)(zhen)材質(zhi)有(you)著突顯(xian)出(chu)的(de)特點：對循壞環節中的(de)參(can)比(bi)探(tan)(tan)針(zhen)(zhen)比(bi)熱容發展有(you)著高包容度，要更(geng)(geng)高地步上規避參(can)比(bi)探(tan)(tan)針(zhen)(zhen)設備(bei)構造毀壞；比(bi)表(biao)面上積大(da)，有(you)益于(yu)于(yu)電(dian)(dian)(dian)解設備(bei)液和參(can)比(bi)探(tan)(tan)針(zhen)(zhen)的(de)能夠(gou)觸碰(peng)，縮小充(chong)充(chong)放電(dian)(dian)(dian)時間；縮小電(dian)(dian)(dian)子廠輸運、化(hua)合物擴撒空(kong)距，提(ti)拔動(dong)(dong)力充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)板電(dian)(dian)(dian)容量(liang)和倍數；協(xie)助執行實行一(yi)些用(yong)途，如無集氣固兩相(xiang)流、自支持(chi)等(deng)。

遺憾的句子的是(shi)，時有史以(yi)來日，硅(gui)奈(nai)(nai)米(mi)級技(ji)術線(xian)(xian)(xian)充(chong)電(dian)(dian)干電(dian)(dian)池板即使是(shi)“左(zuo)思右想(xiang)未下(xia)來”。這難(nan)免讓大家存(cun)疑：是(shi)哪些東(dong)西誘(you)因讓寶馬i3等待的硅(gui)奈(nai)(nai)米(mi)級技(ji)術線(xian)(xian)(xian)充(chong)電(dian)(dian)干電(dian)(dian)池板“小產”？硅(gui)奈(nai)(nai)米(mi)級技(ji)術線(xian)(xian)(xian)充(chong)電(dian)(dian)干電(dian)(dian)池板什(shen)么情(qing)況下(xia)永(yong)遠只要一(yi)項“傳(chuan)說電(dian)(dian)視劇”？

硅奈米線(xian)——動力系統蓄電池負極物料(liao)的辛亥革命？

就現今行勢們來說，電(dian)能導熱系數的增加近乎是(shi)近年(nian)蓄(xu)電(dian)池(chi)制(zhi)造業(ye)，因此是(shi)直流電(dian)動(dong)汽車服(fu)務(wu)業(ye)制(zhi)造業(ye)續航行程(cheng)行程(cheng)前行大跨步最明(ming)星的擊裂(lie)口(kou)。

去年(nian)，韓媒(mei)消息(xi)報了解，韓國集團Amprius成就(jiu)生產制造第一次(ci)批(pi)卡路里孔(kong)隙(xi)率符合450Wh/kg的新幾代(dai)鋰容量(liang)電(dian)(dian)(dian)(dian)(dian)瓶充(chong)電(dian)(dian)(dian)(dian)(dian)。該容量(liang)電(dian)(dian)(dian)(dian)(dian)瓶充(chong)電(dian)(dian)(dian)(dian)(dian)是進(jin)口商(shang)品化容量(liang)電(dian)(dian)(dian)(dian)(dian)瓶充(chong)電(dian)(dian)(dian)(dian)(dian)中卡路里孔(kong)隙(xi)率最快的，所(suo)以(yi)比最旱進(jin)的特斯拉汽車Model 3容量(liang)電(dian)(dian)(dian)(dian)(dian)瓶充(chong)電(dian)(dian)(dian)(dian)(dian)，體積太極大減少了37%。

Amprius工司認為，這牌(pai)干電池可達成是這樣的(de)高的(de)熱量黏度(du)最(zui)主(zhu)要是正因為用到了硅(gui)納米(mi)線技巧，產出的(de)第1 批硅(gui)納米(mi)線鋰干電池已(yi)供給(gei)給(gei)一個高空跳傘偽小行星(xing)工司。。

據(ju)產業界講解，目前為止420～450mAh/g 出水量的硅(gui)基負(fu)極涂料市(shi)價在11～16萬(wan)/噸彼此，500～650 mAh/g的高出水量硅(gui)碳負(fu)極零售價則在10萬(wan)/噸控(kong)制，而中高檔石墨的成本僅有7～8 萬(wan)/噸。
