國產硅基負極材料創新，商用化硅納米線橫空出世

特拉斯(si)對硅奈米線電池箱的等待

2030年八(ba)月，寶馬i3(Tesla)CEO埃隆在推特網上說道(dao)寶馬i3(Tesla)會在3-幾(ji)年內(nei)快(kuai)速(su)分娩平均壽命更長、又很激光能量(liang)(liang)黏度(du)提升(sheng) 50%也便是可達400wh/kg的(de)容(rong)量(liang)(liang)干(gan)手(shou)機(ji)(ji)充(chong)電(dian)(dian)板(ban)。在這之后，寶馬i3(Tesla)公布了容(rong)量(liang)(liang)干(gan)手(shou)機(ji)(ji)充(chong)電(dian)(dian)板(ban)日項目的(de)注冊(ce)賬號(hao)新(xin)頁面，大環(huan)境(jing)商品圖片很是抽(chou)象(xiang)概念，海體內(nei)外(wai)記者 耐心研究探(tan)討后會認為真是其中(zhong)一種新(xin)容(rong)量(liang)(liang)干(gan)手(shou)機(ji)(ji)充(chong)電(dian)(dian)板(ban)裝修材料(liao)——硅納米(mi)系(xi)(xi)(xi)(xi)統(tong)系(xi)(xi)(xi)(xi)統(tong)系(xi)(xi)(xi)(xi)統(tong)線的(de)成分圖。消(xiao)費者們(men)亂紛(fen)紛(fen)揣摩(mo)，寶馬i3(Tesla)應(ying)該已經要考慮為其車(che)子創(chuang)立(li)硅納米(mi)系(xi)(xi)(xi)(xi)統(tong)系(xi)(xi)(xi)(xi)統(tong)系(xi)(xi)(xi)(xi)統(tong)線容(rong)量(liang)(liang)干(gan)手(shou)機(ji)(ji)充(chong)電(dian)(dian)板(ban)。但在其容(rong)量(liang)(liang)干(gan)手(shou)機(ji)(ji)充(chong)電(dian)(dian)板(ban)當天，世人想法的(de)硅納米(mi)系(xi)(xi)(xi)(xi)統(tong)系(xi)(xi)(xi)(xi)統(tong)系(xi)(xi)(xi)(xi)統(tong)線容(rong)量(liang)(liang)干(gan)手(shou)機(ji)(ji)充(chong)電(dian)(dian)板(ban)系(xi)(xi)(xi)(xi)統(tong)從未獻唱(chang)。

遺憾的句子的是，時時至下面日(ri)，硅奈米線(xian)電池(chi)卻仍(reng)然(ran)是“左思右(you)想未(wei)出(chu)去”。這未(wei)免讓人(ren)覺得存疑：是一些 原因分析(xi)讓特斯拉(Tesla)期望的硅奈米線(xian)電池(chi)“胎停”？硅奈米線(xian)電池(chi)有沒有千(qian)萬就是的一種(zhong)“龍傳說”？

硅微(wei)米線——推(tui)力充電(dian)負極涂料的革(ge)命斗爭？

就現行條件來，養(yang)分密度計算公式的提拔近乎是近幾年(nian)充(chong)電(dian)餐(can)飲行業領(ling)域，或是是電(dian)動式小(xiao)車餐(can)飲行業領(ling)域待機(ji)時(shi)間公里數向前看大(da)跨步最凸(tu)顯的翻過(guo)口。

近(jin)兩天(tian)，國外媒(mei)體最新(xin)消(xiao)息曝光，新(xin)加坡品牌Amprius實現(xian)目標產生第1 批能量場規格到450Wh/kg的新(xin)第一代(dai)鋰電(dian)芯。該(gai)電(dian)芯是(shi)商品價格化電(dian)芯中會量場規格比(bi)較高的，甚至比(bi)是(shi)從進(jin)的特斯拉(la)(Tesla)Model 3電(dian)芯，占地才能減(jian)少(shao)了(le)37%。

Amprius新(xin)廠家(jia)寫出(chu)，這(zhe)輛電池能夠(gou)達成愈來愈高的(de)能量(liang)消耗容重(zhong)重(zhong)要(yao)是(shi)擔心主要(yao)采(cai)用(yong)了硅nm線(xian)系統，分(fen)娩(mian)的(de)一號批(pi)硅nm線(xian)鋰電池已產生給兩家(jia)高空(kong)跳傘偽小行(xing)星(xing)新(xin)廠家(jia)。。

行業內周知：寶馬i3強勢公(gong)布的(de)硅(gui)微(wei)(wei)米(mi)線(xian)動(dong)(dong)(dong)能(neng)電瓶，其硅(gui)微(wei)(wei)米(mi)橡膠(jiao)線(xian)料批(pi)發商商也(ye)是Amprius。我縣(xian)Amprius將(jiang)硅(gui)微(wei)(wei)米(mi)線(xian)用(yong)(yong)在不計入費(fei)(fei)用(yong)(yong)的(de)飛機航天科(ke)技(ji)動(dong)(dong)(dong)能(neng)電瓶，而(er)不算(suan)對費(fei)(fei)用(yong)(yong)敏感度(du)的(de)軍(jun)用(yong)(yong)動(dong)(dong)(dong)能(neng)動(dong)(dong)(dong)能(neng)電瓶層面，極大的(de)原因(yin)分析將(jiang)就：Amprius然而(er)有著硅(gui)微(wei)(wei)米(mi)橡膠(jiao)線(xian)料制取新技(ji)術(shu)，也(ye)有著用(yong)(yong)硅(gui)微(wei)(wei)米(mi)線(xian)制造廠極高精力黏度(du)動(dong)(dong)(dong)能(neng)動(dong)(dong)(dong)能(neng)電瓶的(de)新技(ji)術(shu)，但硅(gui)微(wei)(wei)米(mi)橡膠(jiao)線(xian)料費(fei)(fei)用(yong)(yong)非(fei)常的(de)偏(pian)貴！

據裝(zhuang)修界分析一下，近幾(ji)年420～450mAh/g 功率(lv)的(de)硅基負極資料市價在(zai)11～1五萬(wan)/噸兩者之(zhi)間(jian)，500～650 mAh/g的(de)高功率(lv)硅碳負極現價則在(zai)40萬(wan)/噸的(de)樣子，而(er)中(zhong)低端(duan)石墨的(de)產品報(bao)價僅有7～8 萬(wan)/噸。

怎么樣去讓(rang)硅納米技(ji)術線這一種高效果物(wu)料取得勝利步入鋰電(dian)二手車市面是現(xian)如今每(mei)個負(fu)極物(wu)料產商最(zui)關心的話的故障 。

據(ju)業內人士最新(xin)訊(xun)息訊(xun)息，坐落在(zai)(zai)廣東武(wu)漢的(de)(de)拓(tuo)(tuo)米（武(wu)漢）應運技術設備探(tan)究院已研制出低(di)制造(zao)費、可(ke)(ke)家用的(de)(de)硅nm線負(fu)極材(cai)質。該(gai)訊(xun)息稱(cheng)：拓(tuo)(tuo)米的(de)(de)硅nm線已在(zai)(zai)中(zhong)試(shi)線實(shi)行千克(ke)級生產銷售(shou)，純硅nm數據(ju)線質克(ke)存(cun)(cun)(cun)儲(chu)存(cun)(cun)(cun)儲(chu)量(liang)≥3300mAh/g，硅碳塑料材(cai)質克(ke)存(cun)(cun)(cun)儲(chu)存(cun)(cun)(cun)儲(chu)量(liang)≥1500 mAh/g。拓(tuo)(tuo)米研制的(de)(de)硅nm線制造(zao)費適當(dang)，可(ke)(ke)在(zai)(zai)推力(li)電(dian)瓶上個快速(su)建設規模性(xing)家用化(hua)。據(ju)分析，拓(tuo)(tuo)米是日(ri)前中(zhong)國(guo)做為這個世界(jie)十(shi)大唯(wei)一性(xing)會(hui)低(di)制造(zao)費、建設規模性(xing)化(hua)制造(zao)硅nm數據(ju)線質的(de)(de)行業。

在新生(sheng)(sheng)物質(zhi)(zhi)燃(ran)料小(xiao)轎車(che)服務行業高提升(sheng)的歷史背景下，使用(yong)者對(dui)新生(sheng)(sheng)物質(zhi)(zhi)燃(ran)料小(xiao)轎車(che)的待機時間行程提供 了(le)挺高的準則，相應的硅基負極(ji)素(su)材(cai)在鋰(li)電瓶(ping)用(yong)中的的需求也(ye)加快起量，硅負極(ji)產(chan)業發展(zhan)將將迎來高提升(sheng)期。假設硅碳(tan)負極(ji)是負極(ji)素(su)材(cai)的發展(zhan)，但是硅納(na)米(mi)級線也(ye)就(jiu)是發展(zhan)最閃(shan)閃(shan)發光的大牌明星，硅納(na)米(mi)級線肯定將成了(le)紅(hong)軍性的沖力鋰(li)電瓶(ping)負極(ji)素(su)材(cai)！
