盡管國家大力(li)推(tui)行(xing)鋰電，但(dan)鉛酸電池(chi)依然在(zai)電動(dong)自行(xing)車市場占據主(zhu)導。業內(nei)人士認為，除了價格方(fang)面，鉛酸電池(chi)的(de)市場循環方(fang)面更好也是鋰電池(chi)難以(yi)替代的(de)一個重要(yao)因(yin)素。
南都電(dian)(dian)(dian)源鋰電(dian)(dian)(dian)池(chi)(chi)(chi)技術負責(ze)人李小平表(biao)示，在(zai)(zai)電(dian)(dian)(dian)動自(zi)行(xing)(xing)車(che)市場上(shang)，鋰電(dian)(dian)(dian)池(chi)(chi)(chi)“打不過”鉛(qian)(qian)酸電(dian)(dian)(dian)池(chi)(chi)(chi)，除了鋰電(dian)(dian)(dian)自(zi)行(xing)(xing)車(che)在(zai)(zai)性能上(shang)沒有更突(tu)出的表(biao)現外，電(dian)(dian)(dian)池(chi)(chi)(chi)的循環回(hui)收也是一個重要(yao)因(yin)素。當客(ke)戶購買鉛(qian)(qian)酸電(dian)(dian)(dian)池(chi)(chi)(chi)自(zi)行(xing)(xing)車(che)以后，電(dian)(dian)(dian)池(chi)(chi)(chi)不用(yong)了，將電(dian)(dian)(dian)池(chi)(chi)(chi)還給供應商，能回(hui)收30%的電(dian)(dian)(dian)池(chi)(chi)(chi)費用(yong)，在(zai)(zai)這種情況下(xia)，鋰電(dian)(dian)(dian)自(zi)行(xing)(xing)車(che)無法(fa)與鉛(qian)(qian)酸電(dian)(dian)(dian)池(chi)(chi)(chi)自(zi)行(xing)(xing)車(che)競爭(zheng)。
此外(wai)，李小平表(biao)示(shi)，在大(da)(da)規模的(de)(de)電站儲能(neng)方面，國家(jia)曾經推(tui)行過磷酸(suan)(suan)鐵(tie)鋰電池，不過較(jiao)近又返回到鉛(qian)酸(suan)(suan)電池上來。這主要是因為鉛(qian)酸(suan)(suan)電池投資較(jiao)少(shao)、安全性(xing)風險(xian)不大(da)(da)，而且50%的(de)(de)鉛(qian)酸(suan)(suan)廢(fei)舊(jiu)電池可以回收。
盡管鋰電池耐用性相對更強，體積相對較小，但鋰電池還難以大規模取代鉛酸電池的主要原因是價格。業內人士認為，當前，鋰離子電池的價格是鉛酸電池的3倍左右，預計明年鋰電池的價格有望降至鉛酸電池價格的2倍。如果能降到2倍以下，鋰電池的性價比就會凸顯。
