從技術潛力角度來看,三元動力鋰電池能量密度提升相對困難,全固態鋰電池能量密度提升,從理論上講更具可行性。一是全固態鋰電池電(dian)(dian)壓平臺提升(sheng),固(gu)態電(dian)(dian)解(jie)(jie)質比有(you)(you)機電(dian)(dian)解(jie)(jie)液普(pu)遍具有(you)(you)更寬的(de)(de)(de)電(dian)(dian)化學(xue)窗口,有(you)(you)利(li)于(yu)進(jin)一步提升(sheng)電(dian)(dian)池的(de)(de)(de)能(neng)量密(mi)度(du)(du);二是固(gu)態電(dian)(dian)解(jie)(jie)質能(neng)阻(zu)隔鋰(li)(li)(li)枝晶生長(chang),材料應(ying)用體系(xi)范圍大幅(fu)提升(sheng),為(wei)具有(you)(you)更高(gao)能(neng)量密(mi)度(du)(du)空(kong)(kong)間的(de)(de)(de)新型(xing)鋰(li)(li)(li)電(dian)(dian)技術奠定(ding)基礎。三(san)是全固(gu)態鋰(li)(li)(li)電(dian)(dian)池當前能(neng)量密(mi)度(du)(du)約400Wh/Kg,預估最(zui)大潛力值達900Wh/Kg,有(you)(you)超過100%的(de)(de)(de)提升(sheng)空(kong)(kong)間。固(gu)態鋰(li)(li)(li)電(dian)(dian)池必將是未來的(de)(de)(de)主(zhu)流產(chan)品。

固態(tai)鋰(li)(li)(li)(li)電(dian)(dian)(dian)(dian)池(chi):安(an)全(quan)性高,可(ke)大(da)幅(fu)降(jiang)低車輛自(zi)燃率，近年來國內(nei)外多(duo)次出現新(xin)能(neng)源(yuan)汽車自(zi)燃事故(gu),新(xin)能(neng)源(yuan)汽車的(de)使用(yong)越(yue)來越(yue)關(guan)注。其主要(yao)原(yuan)因在(zai)于動力電(dian)(dian)(dian)(dian)池(chi)(三(san)元鋰(li)(li)(li)(li)為主)的(de)問題,三(san)元鋰(li)(li)(li)(li)電(dian)(dian)(dian)(dian)池(chi)的(de)電(dian)(dian)(dian)(dian)氣安(an)全(quan)、功能(neng)安(an)全(quan)、化學安(an)全(quan)、機械安(an)全(quan)方面控制仍不給力。一般而言,三(san)元鋰(li)(li)(li)(li)電(dian)(dian)(dian)(dian)池(chi)液態(tai)電(dian)(dian)(dian)(dian)解質(zhi)易(yi)燃易(yi)爆,在(zai)長(chang)期使用(yong)過程(cheng)中容(rong)易(yi)觸發“熱失控”,在(zai)充放(fang)電(dian)(dian)(dian)(dian)過程(cheng)中鋰(li)(li)(li)(li)枝(zhi)晶(jing)的(de)生長(chang)容(rong)易(yi)刺破隔膜,引起電(dian)(dian)(dian)(dian)池(chi)短路(lu),造成(cheng)安(an)全(quan)隱患(huan)。但是全(quan)固態(tai)鋰(li)(li)(li)(li)電(dian)(dian)(dian)(dian)池(chi)則具有極高的(de)安(an)全(quan)性,其固態(tai)電(dian)(dian)(dian)(dian)解質(zhi)不可(ke)燃、無腐蝕、不揮(hui)發、不漏液,同時也克服了鋰(li)(li)(li)(li)枝(zhi)晶(jing)現象,搭載全(quan)固態(tai)鋰(li)(li)(li)(li)電(dian)(dian)(dian)(dian)池(chi)的(de)汽車的(de)自(zi)燃概(gai)率會大(da)大(da)降(jiang)低。

綜合上述產品、技術、安全等方面的比較,全固態鋰電池在使用安全和技術潛力方面具有絕對的優勢,但是三元鋰電在產品(pin)成熟度(du)、市(shi)場滲透方(fang)面具有相當(dang)的(de)優勢。綜合(he)來(lai)看,當(dang)前(qian)采(cai)用三元(yuan)鋰電(dian)是純電(dian)動(dong)汽車最為明(ming)智(zhi)的(de)選(xuan)擇。但(dan)是,一旦(dan)全固態鋰電(dian)池(chi)解(jie)決金屬(shu)鋰穩定性差等問題后(hou),將爆發強大的(de)產品(pin)替代力,或將顛(dian)覆(fu)動(dong)力電(dian)池(chi)產業格局。
