: 據報導,日前寧德時代在電話會議上表示,三季度電池系統銷量90GWh左右。同時還透露
: ,公司鈉離子電池產業化進展順利,供應鏈佈局上需要一些時間,已與部分乘用車客戶協
: 商,明年將會正式量產。
: 據悉,寧德時代在2021年率先發佈了第一代鈉離子電池,電芯單體能量密度達到160Wh/kg
: ,創下全球最高水平。
: 從快充和低溫性能來看,在充電15分鐘的情況下就能達到80%的容量,在零下20℃的低溫
: 環境下,仍能保持90%以上的放電保持率。
: 對比磷酸鐵鋰電池,寧德時代第一代鈉離子電池幾乎全方位勝出,在安全性、快充、低溫
: 性能等方面都處於領先地位,唯一的不足就是能量密度稍弱。
: 不過,寧德時代已經在規劃第二代鈉離子電池,稱將把能量密度做到200Wh/kg以上。
: 有研究機構報告顯示,鈉離子電池充放電倍率性能出色,可滿足兩輪電動車、電動工具、
: 儲能、A00級電動車的能量密度要求,充分發揮鈉離子電池充放電倍率性能佳,安全性優
: 異的特點。
: ========================
: 相對鋰的昂貴和烯少性,納太多地方能採取到且價格只有鋰的1/50,未來的電動車的電池
: 成本應該會大幅降低,還可以有效解決低溫下電池衰退問題
: 納離子電池最大且唯一的缺點就是車重會增加
中國奇瑞汽車已經官宣首發採用寧德時代的鈉電池
並推出合作電池品牌 ENER-Q
就目前流出的資料
二代的鈉離子電池的能量密度約同LFP
但是冬季性能衰減少
且成本低LFP電池約15%
並且解放了鋰的依賴
且更安全
如果量產的參數有這麼好的話
有望替代LFP電池成為入門電動車首選
