動力鋰電池與儲能磷酸鐵鋰電池的區別
隨著磷酸鐵鋰電池技術逐漸成熟、成本的逐步下降,中國儲能市場逐漸鋪展開來。電動工具電池的容量不大,且不需要提供大功率輸出;而儲能磷
動力鋰電池(chi)與儲能磷酸鐵(tie)鋰電池(chi)的區(qu)別
隨(sui)著(zhu)磷(lin)(lin)酸(suan)鐵(tie)鋰(li)電(dian)(dian)(dian)(dian)(dian)池(chi)技(ji)術逐漸(jian)(jian)成熟、成本的(de)(de)逐步(bu)下(xia)降(jiang),中國(guo)儲能(neng)(neng)市場(chang)(chang)逐漸(jian)(jian)鋪展(zhan)(zhan)開來(lai)。電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)工(gong)具電(dian)(dian)(dian)(dian)(dian)池(chi)的(de)(de)容量(liang)不(bu)(bu)大(da),且不(bu)(bu)需要(yao)提供大(da)功率輸(shu)出;而儲能(neng)(neng)磷(lin)(lin)酸(suan)鐵(tie)鋰(li)電(dian)(dian)(dian)(dian)(dian)池(chi)主要(yao)是提供動(dong)(dong)力(li)用,要(yao)求能(neng)(neng)夠(gou)輸(shu)出高功率。其次,相(xiang)對(dui)于動(dong)(dong)力(li)鋰(li)電(dian)(dian)(dian)(dian)(dian)池(chi)而言,儲能(neng)(neng)磷(lin)(lin)酸(suan)鐵(tie)鋰(li)電(dian)(dian)(dian)(dian)(dian)池(chi)對(dui)于使用壽命有更高的(de)(de)要(yao)求。價格預計,相(xiang)同規(gui)格的(de)(de),前者是后者的(de)(de)1.2倍。動(dong)(dong)力(li)鋰(li)電(dian)(dian)(dian)(dian)(dian)池(chi)與(yu)儲能(neng)(neng)磷(lin)(lin)酸(suan)鐵(tie)鋰(li)電(dian)(dian)(dian)(dian)(dian)池(chi)的(de)(de)區別。儲能(neng)(neng)電(dian)(dian)(dian)(dian)(dian)池(chi)與(yu)動(dong)(dong)力(li)磷(lin)(lin)酸(suan)鐵(tie)鋰(li)電(dian)(dian)(dian)(dian)(dian)池(chi)是不(bu)(bu)一(yi)樣的(de)(de)。隨(sui)著(zhu)磷(lin)(lin)酸(suan)鐵(tie)鋰(li)電(dian)(dian)(dian)(dian)(dian)池(chi)技(ji)術逐漸(jian)(jian)成熟、成本的(de)(de)逐步(bu)下(xia)降(jiang),中國(guo)儲能(neng)(neng)市場(chang)(chang)逐漸(jian)(jian)鋪展(zhan)(zhan)開來(lai)。
動力鋰(li)電(dian)(dian)(dian)池與(yu)儲(chu)能(neng)磷酸(suan)鐵(tie)鋰(li)電(dian)(dian)(dian)池的區別(bie)。儲(chu)能(neng)電(dian)(dian)(dian)池與(yu)動力磷酸(suan)鐵(tie)鋰(li)電(dian)(dian)(dian)池是不一樣的。隨著磷酸(suan)鐵(tie)鋰(li)電(dian)(dian)(dian)池技術逐(zhu)漸成熟、成本的逐(zhu)步下(xia)降,中國儲(chu)能(neng)市場逐(zhu)漸鋪展(zhan)開(kai)來,近幾年儲(chu)能(neng)行業發(fa)展(zhan)迅(xun)速、進入快速成長期(qi)。除(chu)了動力電(dian)(dian)(dian)池領域(yu),儲(chu)能(neng)市場成為(wei)拉動鋰(li)電(dian)(dian)(dian)池產銷(xiao)量(liang)的另一增長點。
動力鋰電池與儲能磷酸鐵鋰電池的區別:
電壓大小不同
在電(dian)(dian)(dian)池(chi)行業(ye)上,電(dian)(dian)(dian)壓(ya)增(zeng)大(da)了,其對應的(de)(de)(de)輸(shu)出電(dian)(dian)(dian)壓(ya)也會增(zeng)大(da),從而(er)使(shi)得(de)動力(li)型鋰(li)電(dian)(dian)(dian)池(chi)組能夠滿足(zu)一(yi)些大(da)功率的(de)(de)(de)設備上;而(er)并聯方式(shi)直接(jie)影響(xiang)的(de)(de)(de)結果(guo)就(jiu)是使(shi)得(de)整個電(dian)(dian)(dian)池(chi)組的(de)(de)(de)電(dian)(dian)(dian)流(liu)增(zeng)大(da),而(er)容(rong)量是受輸(shu)出端(duan)的(de)(de)(de)電(dian)(dian)(dian)流(liu)影響(xiang)的(de)(de)(de),所(suo)以并聯的(de)(de)(de)直接(jie)作用(yong)就(jiu)是使(shi)得(de)鋰(li)電(dian)(dian)(dian)池(chi)組的(de)(de)(de)容(rong)量增(zeng)大(da),以這種方式(shi)連接(jie)的(de)(de)(de)電(dian)(dian)(dian)池(chi)組的(de)(de)(de)容(rong)量往往會比(bi)較(jiao)大(da),也就(jiu)是所(suo)謂的(de)(de)(de)容(rong)量型鋰(li)電(dian)(dian)(dian)池(chi)組。
動力(li)(li)鋰(li)電(dian)池主(zhu)要(yao)(yao)(yao)用于能(neng)量(liang)存儲,容量(liang)要(yao)(yao)(yao)求(qiu)大,壽命要(yao)(yao)(yao)求(qiu)長,是自放電(dian)低的。電(dian)動工具電(dian)池的容量(liang)不(bu)大,且(qie)不(bu)需(xu)要(yao)(yao)(yao)提(ti)供大功率(lv)輸(shu)出;而儲能(neng)磷酸鐵鋰(li)電(dian)池主(zhu)要(yao)(yao)(yao)是提(ti)供動力(li)(li)用,要(yao)(yao)(yao)求(qiu)能(neng)夠(gou)輸(shu)出高(gao)功率(lv)。
應用的產品不同
一些(xie)大(da)型(xing)設備(bei)上(shang)需要的(de)電(dian)壓值(zhi)較高(gao),因為(wei)小功率的(de)電(dian)池(chi)組(zu)(zu)帶不起運轉(zhuan),所以就(jiu)要選用(yong)動(dong)力(li)型(xing)鋰(li)(li)電(dian)池(chi)組(zu)(zu)。例如我們(men)(men)平時(shi)所用(yong)的(de)電(dian)動(dong)自行(xing)車,它所要求的(de)電(dian)壓值(zhi)往(wang)往(wang)都是48V,相對我們(men)(men)生活中的(de)一些(xie)情況,48V已(yi)經算是不小了。所以就(jiu)必須使(shi)用(yong)動(dong)力(li)型(xing)鋰(li)(li)電(dian)池(chi)組(zu)(zu)來(lai)確保電(dian)動(dong)自行(xing)車的(de)運轉(zhuan)。而我們(men)(men)平時(shi)去一些(xie)大(da)型(xing)超市(shi)或(huo)者(zhe)(zhe)商場,一些(xie)標志燈以及備(bei)用(yong)電(dian)源,因為(wei)這些(xie)設備(bei)的(de)功耗并不是很大(da),所以一般都采用(yong)容量型(xing)鋰(li)(li)電(dian)池(chi)組(zu)(zu),這兩(liang)者(zhe)(zhe)之間在產品的(de)應用(yong)上(shang)是不同的(de)。
動力(li)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)和(he)(he)儲能(neng)(neng)磷酸(suan)鐵鋰電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的(de)區別首先(xian)是(shi)(shi)針對(dui)用(yong)(yong)(yong)途不一(yi)樣來設計(ji)(ji)的(de),動力(li)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)顯然(ran)用(yong)(yong)(yong)于(yu)(yu)電(dian)(dian)(dian)動汽車(che),儲能(neng)(neng)磷酸(suan)鐵鋰電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)應用(yong)(yong)(yong)于(yu)(yu)儲能(neng)(neng)電(dian)(dian)(dian)站(zhan)、調(diao)峰調(diao)頻電(dian)(dian)(dian)力(li)輔助(zhu)服(fu)務(wu)等。有人形(xing)象的(de)將(jiang)動力(li)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)比喻為發電(dian)(dian)(dian)機,儲能(neng)(neng)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)就相當(dang)于(yu)(yu)轉換器。雖然(ran)動力(li)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)和(he)(he)儲能(neng)(neng)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)同(tong)屬電(dian)(dian)(dian)化(hua)學應用(yong)(yong)(yong)領(ling)域,技術(shu)要(yao)求都(dou)比較高,但(dan)相比之下它(ta)們應用(yong)(yong)(yong)場景(jing)不同(tong)、對(dui)于(yu)(yu)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的(de)性能(neng)(neng)各有側重點,其性能(neng)(neng)和(he)(he)設計(ji)(ji)也是(shi)(shi)不一(yi)樣。
動力鋰電(dian)池(chi)更側(ce)重于充(chong)放電(dian)功率等(deng)方面(mian),要求充(chong)電(dian)速率快、輸(shu)出(chu)功率高、耐震動,尤其(qi)強調較高的安全性(xing)和高能(neng)量(liang)(liang)密度(du)以達(da)到持久續航(hang)能(neng)力,還有重量(liang)(liang)體積方面(mian)的輕量(liang)(liang)要求。從電(dian)池(chi)材(cai)料方面(mian)就要考(kao)量(liang)(liang)電(dian)池(chi)正負(fu)極材(cai)料性(xing)能(neng)以及(ji)電(dian)解液(ye)和隔膜(mo)相關性(xing)能(neng)。
而儲能設備(bei)(bei)而且(qie)一(yi)(yi)般(ban)規模(mo)較大、固定裝置無需移動,一(yi)(yi)般(ban)對重量和體積(ji)沒有太高(gao)要(yao)求。儲能磷酸鐵鋰電池(chi)的(de)制備(bei)(bei)強調電池(chi)容量,尤其要(yao)求運行穩定性和使用壽命,多考慮電池(chi)模(mo)塊一(yi)(yi)致性,電池(chi)材(cai)料方面(mian)就(jiu)要(yao)關注膨脹率和能量密度(du)、電極材(cai)料性能均(jun)勻(yun)性等方面(mian),以追求整體儲能設備(bei)(bei)的(de)長壽命和低(di)成本(ben)。
其次(ci),相(xiang)對于動力(li)鋰(li)(li)電(dian)池而言,儲(chu)能(neng)(neng)磷(lin)酸鐵(tie)(tie)鋰(li)(li)電(dian)池對于使用壽命(ming)(ming)有更高的(de)(de)要求。新(xin)能(neng)(neng)源汽車的(de)(de)壽命(ming)(ming)一般在(zai)5-8年,而儲(chu)能(neng)(neng)項目的(de)(de)壽命(ming)(ming)一般都希望大(da)(da)于10年。動力(li)鋰(li)(li)電(dian)池的(de)(de)循環次(ci)數壽命(ming)(ming)在(zai)1000-2000次(ci),而儲(chu)能(neng)(neng)磷(lin)酸鐵(tie)(tie)鋰(li)(li)電(dian)池的(de)(de)循環次(ci)數壽命(ming)(ming)一般要求能(neng)(neng)夠(gou)大(da)(da)于3500次(ci),并且(qie)希望通過開發新(xin)型的(de)(de)運維再生技術,以達到超長(chang)的(de)(de)儲(chu)能(neng)(neng)壽命(ming)(ming)。
價(jia)格(ge)不同(tong),動(dong)力(li)電(dian)池(chi)的(de)(de)價(jia)格(ge)會(hui)比(bi)儲(chu)(chu)能(neng)(neng)到1.5倍以上(根據(ju)客戶的(de)(de)不同(tong)要求(qiu)來定(ding)的(de)(de))。儲(chu)(chu)能(neng)(neng)電(dian)池(chi)一(yi)般(ban)電(dian)流小,屬于能(neng)(neng)量(liang)型(xing),動(dong)力(li)電(dian)池(chi)一(yi)般(ban)要能(neng)(neng)3C放(fang)電(dian)。可以通過3C放(fang)電(dian)或(huo)者1.5C放(fang)電(dian)來比(bi)較(jiao)放(fang)電(dian)容量(liang)或(huo)者放(fang)電(dian)曲線(xian)、平(ping)臺。價(jia)格(ge)預(yu)計(ji),相同(tong)規格(ge)的(de)(de),前者是后者的(de)(de)1.2倍。
以上(shang)就(jiu)是(shi)動(dong)力(li)鋰電(dian)池(chi)(chi)與儲(chu)能(neng)磷酸鐵鋰電(dian)池(chi)(chi)的(de)區別,相對動(dong)力(li)鋰電(dian)池(chi)(chi)而言(yan),儲(chu)能(neng)電(dian)池(chi)(chi)是(shi)將安全性(xing)、循環(huan)性(xing)能(neng)和成本(ben)放在第(di)一位的(de),并不苛求很好的(de)倍率性(xing)能(neng)和溫度性(xing)能(neng),因此(ci)儲(chu)能(neng)用途鋰電(dian)池(chi)(chi)對材料(liao)的(de)指標及電(dian)池(chi)(chi)材料(liao)配比的(de)要求和動(dong)力(li)電(dian)池(chi)(chi)有較大的(de)不同。
