本(ben)發(fa)明(ming)涉及(ji)鈉離子電池，具體(ti)為一種(zhong)鈉離子電池用新型復(fu)合(he)負極結構(gou)及(ji)其(qi)制備(bei)方法(fa)。

背景技術：

1、鈉(na)(na)(na)離(li)(li)子電(dian)(dian)(dian)(dian)池(chi)(chi)是一(yi)種(zhong)(zhong)充電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)(chi)，主要通過鈉(na)(na)(na)離(li)(li)子在(zai)(zai)正(zheng)極和負極間(jian)移(yi)動(dong)進(jin)行工作，與鋰離(li)(li)子電(dian)(dian)(dian)(dian)池(chi)(chi)工作原理相似(si)。近(jin)期，鈉(na)(na)(na)離(li)(li)子電(dian)(dian)(dian)(dian)池(chi)(chi)因韓國開發的(de)(de)能在(zai)(zai)幾秒(miao)鐘內完成充電(dian)(dian)(dian)(dian)的(de)(de)高能量、高功率鈉(na)(na)(na)離(li)(li)子混合(he)電(dian)(dian)(dian)(dian)池(chi)(chi)而備受關注。這種(zhong)(zhong)技術(shu)如果應用到(dao)電(dian)(dian)(dian)(dian)動(dong)汽車等領域，將(jiang)大(da)大(da)提高效率并(bing)帶來巨大(da)的(de)(de)經濟效益。中(zhong)國也在(zai)(zai)鈉(na)(na)(na)離(li)(li)子電(dian)(dian)(dian)(dian)池(chi)(chi)領域取(qu)得(de)顯著(zhu)進(jin)展，許多車企和電(dian)(dian)(dian)(dian)池(chi)(chi)制造商(shang)都在(zai)(zai)研發鈉(na)(na)(na)電(dian)(dian)(dian)(dian)池(chi)(chi)產品，預計2024年(nian)(nian)將(jiang)是鈉(na)(na)(na)電(dian)(dian)(dian)(dian)池(chi)(chi)規模化運營的(de)(de)元年(nian)(nian)，新型(xing)復合(he)負極結構是指在(zai)(zai)鈉(na)(na)(na)離(li)(li)子電(dian)(dian)(dian)(dian)池(chi)(chi)負極材料中(zhong)采用的(de)(de)一(yi)種(zhong)(zhong)復合(he)結構，旨在(zai)(zai)提高電(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)電(dian)(dian)(dian)(dian)化學性能，包括能量密度、循環穩定性和安(an)全(quan)性能。

2、現有復合負極(ji)(ji)結構中(zhong)有采用(yong)(yong)(yong)電(dian)鍍銅箔替代傳統銅箔，但電(dian)鍍銅不僅對(dui)環境產生污染并且(qie)達(da)到一(yi)定(ding)厚度的鍍銅層易產生脫落。同時，銅表(biao)面容易氧化導(dao)(dao)致(zhi)(zhi)導(dao)(dao)電(dian)性(xing)能下降，進而影響(xiang)電(dian)池(chi)的性(xing)能，且(qie)大(da)多通過(guo)焊接(jie)(jie)的方式(shi)將電(dian)池(chi)負極(ji)(ji)片電(dian)性(xing)連接(jie)(jie)在電(dian)芯負極(ji)(ji)上，穩定(ding)性(xing)較差，使用(yong)(yong)(yong)過(guo)程中(zhong)電(dian)池(chi)受到震動易導(dao)(dao)致(zhi)(zhi)連接(jie)(jie)焊點脫落，從而影響(xiang)了(le)電(dian)池(chi)的供電(dian)效果和使用(yong)(yong)(yong)壽命。

3、為此，本(ben)領域技術(shu)人(ren)員提供一種鈉離子電池(chi)用新型復合(he)負極(ji)結構及其(qi)制(zhi)備方法，以解決(jue)上述問(wen)題(ti)。
