還有很多人有這樣的疑惑：鋰電池不是(shi)(shi)都一樣嗎，能有什么(me)(me)區別(bie)。如果(guo)要(yao)真正了(le)(le)解動(dong)力(li)鋰(li)電(dian)(dian)池和普(pu)通3C鋰(li)電(dian)(dian)池本質應用(yong)需求的話，動(dong)力(li)鋰(li)電(dian)(dian)池和普(pu)通3C鋰(li)電(dian)(dian)池區別(bie)有哪些(xie)想必(bi)會比較(jiao)了(le)(le)解，那么(me)(me)動(dong)力(li)鋰(li)電(dian)(dian)池與普(pu)通3C鋰(li)電(dian)(dian)池的區別(bie)是(shi)(shi)什么(me)(me)呢？

一、動力(li)鋰電(dian)池(chi)和普通3C鋰電(dian)池(chi)區別在應(ying)用方(fang)面分析：

1、動(dong)力鋰(li)電(dian)池可以應用在電(dian)動(dong)汽車，電(dian)動(dong)車，電(dian)動(dong)工具等(deng)大倍率放電(dian)的(de)產品上面(mian)，而(er)普通3C鋰(li)電(dian)池僅用于(yu)手(shou)機(ji)，手(shou)環，數碼像機(ji)，筆記本電(dian)腦，移(yi)動(dong)電(dian)源等(deng)方(fang)面(mian)，只(zhi)能滿員普通放電(dian)供(gong)電(dian)使用需求(qiu)。

2、電(dian)(dian)(dian)池(chi)放(fang)(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)在產品(pin)應用中，可以(yi)理解(jie)動力鋰電(dian)(dian)(dian)池(chi)一般是指基本以(yi)5C電(dian)(dian)(dian)流(liu)放(fang)(fang)電(dian)(dian)(dian)為標(biao)準(zhun)(zhun)，如果是超高倍(bei)率的動力電(dian)(dian)(dian)池(chi)可以(yi)10C或30C更大的電(dian)(dian)(dian)流(liu)進(jin)行(xing)放(fang)(fang)電(dian)(dian)(dian)；普通(tong)3C鋰電(dian)(dian)(dian)池(chi)一般以(yi)3C以(yi)下電(dian)(dian)(dian)流(liu)放(fang)(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)為標(biao)準(zhun)(zhun)判(pan)斷。

二、動力鋰(li)電池(chi)和普通3C鋰(li)電池(chi)別在設計方面分析(xi)：

1、磷酸鐵鋰動力(li)(li)類鋰離子電(dian)池在研發設(she)計(ji)時需要(yao)更(geng)多考(kao)(kao)慮(lv)可靠(kao)性(xing)(xing)和(he)一(yi)致性(xing)(xing)，畢(bi)竟(jing)要(yao)長時間(jian)（至少5~10年(nian)）、惡劣環(huan)境（冬天低溫(wen)、夏天暴曬、雨雪）、大量電(dian)池串并聯配組使用(yong)，考(kao)(kao)慮(lv)可靠(kao)性(xing)(xing)和(he)一(yi)致性(xing)(xing)，假設(she)一(yi)輛汽車(che)使用(yong)1000只動力(li)(li)電(dian)池，理想(xiang)上，汽車(che)廠家希望一(yi)個車(che)型10萬輛車(che)的(de)(de)規模(mo)下(xia)不要(yao)出(chu)問(wen)題，也(ye)就是理想(xiang)上要(yao)求動力(li)(li)電(dian)池出(chu)問(wen)題（安全、存儲、循環(huan)等）的(de)(de)幾率(lv)要(yao)在一(yi)億分(fen)之一(yi)以下(xia)（當然對于最(zui)高端(duan)消費類電(dian)池而言，蘋(pin)果也(ye)對供(gong)應(ying)商要(yao)求到了這個級別）。考(kao)(kao)慮(lv)到可靠(kao)性(xing)(xing)，動力(li)(li)類電(dian)池一(yi)般設(she)計(ji)冗余更(geng)多，使用(yong)更(geng)厚的(de)(de)隔(ge)膜、箔材和(he)外(wai)殼，因此能量密度也(ye)就大概是消費類電(dian)池的(de)(de)一(yi)半(ban)吧。

2、普通消(xiao)費類鋰離子(zi)電池研發設計時(shi)更多的需(xu)要(yao)(yao)考(kao)慮安全性和耐(nai)久性，無需(xu)長時(shi)間(jian)可靠性（循環也無需(xu)做(zuo)得太好，因為反正一兩(liang)年就會換），一般不需(xu)要(yao)(yao)配(pei)組單獨使用，所(suo)以對(dui)(dui)一致性沒有太大要(yao)(yao)求，但是由于消(xiao)費類的手機、pad平板電腦(nao)空間(jian)有限并且非常珍貴，因此消(xiao)費類鋰離子(zi)電池對(dui)(dui)于尺寸要(yao)(yao)求嚴格(ge)、容量、能量密度等要(yao)(yao)求很高。

3、動力鋰(li)(li)電(dian)(dian)池和(he)普通(tong)鋰(li)(li)電(dian)(dian)區(qu)別對于產品安(an)全而言，動力電(dian)(dian)池有更多的(de)外部保護電(dian)(dian)路、散(san)熱布(bu)局(ju)等，當然也面臨(lin)更惡劣的(de)條(tiao)件（更高(gao)的(de)外部電(dian)(dian)壓、更大的(de)電(dian)(dian)流、更復雜(za)的(de)外部環境），消費類電(dian)(dian)池的(de)保護更少，要在更高(gao)能量密度的(de)基礎(chu)上靠電(dian)(dian)池的(de)材(cai)料(liao)(liao)和(he)設計抗住各種危及安(an)全的(de)情況；而高(gao)端的(de)消費類手機鋰(li)(li)電(dian)(dian)池使(shi)用了最先進的(de)技(ji)術(shu)和(he)材(cai)料(liao)(liao)，而動力電(dian)(dian)池更多是(shi)需(xu)要先進的(de)工藝控制、一致性控制和(he)質量管理。

三(san)、動力鋰電池和普(pu)通鋰電區別在性能(neng)方面分析：

1、比(bi)如(ru)說磷酸(suan)鐵(tie)鋰(li)(li)動力(li)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)以磷酸(suan)鐵(tie)鋰(li)(li)LiFeCoPO4橄欖石結(jie)構(gou)的鋰(li)(li)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)正(zheng)(zheng)(zheng)極(ji)材(cai)(cai)(cai)料為(wei)(wei)主(zhu)，磷酸(suan)鐵(tie)鋰(li)(li)動力(li)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)是一類由鋰(li)(li)金屬(shu)或(huo)鋰(li)(li)合金為(wei)(wei)正(zheng)(zheng)(zheng)極(ji)材(cai)(cai)(cai)料、使(shi)用非(fei)水(shui)電(dian)(dian)(dian)解質(zhi)溶(rong)液的電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)；而普通鋰(li)(li)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)以錳酸(suan)鋰(li)(li)正(zheng)(zheng)(zheng)極(ji)材(cai)(cai)(cai)料為(wei)(wei)主(zhu)，主(zhu)要為(wei)(wei)尖晶(jing)石型錳酸(suan)鋰(li)(li)材(cai)(cai)(cai)料，尖晶(jing)石型錳酸(suan)鋰(li)(li)LiMn2O4是Hunter在1981年首先制得的具有三維鋰(li)(li)離子通道(dao)的正(zheng)(zheng)(zheng)極(ji)材(cai)(cai)(cai)料；但是隨著鋰(li)(li)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)正(zheng)(zheng)(zheng)極(ji)材(cai)(cai)(cai)料有哪些(xie)發展(zhan)趨勢可(ke)能會有更多優質(zhi)的正(zheng)(zheng)(zheng)極(ji)材(cai)(cai)(cai)料代替現在材(cai)(cai)(cai)料，但是無論怎么(me)樣(yang)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)材(cai)(cai)(cai)料安全應用更重(zhong)要。

2、磷(lin)酸(suan)(suan)(suan)鐵(tie)(tie)鋰(li)(li)動力電(dian)(dian)(dian)(dian)池(chi)和鋰(li)(li)電(dian)(dian)(dian)(dian)池(chi)的(de)電(dian)(dian)(dian)(dian)壓(ya)(ya)區別發現常用鋰(li)(li)電(dian)(dian)(dian)(dian)池(chi)的(de)主要優點有哪些？磷(lin)酸(suan)(suan)(suan)鐵(tie)(tie)鋰(li)(li)動力電(dian)(dian)(dian)(dian)池(chi)平臺標準(zhun)電(dian)(dian)(dian)(dian)壓(ya)(ya)為(wei)(wei)3.2V，充滿電(dian)(dian)(dian)(dian)為(wei)(wei)3.65V，磷(lin)酸(suan)(suan)(suan)鐵(tie)(tie)鋰(li)(li)電(dian)(dian)(dian)(dian)芯放電(dian)(dian)(dian)(dian)截止電(dian)(dian)(dian)(dian)壓(ya)(ya)為(wei)(wei)2.0V；而普通(tong)鋰(li)(li)電(dian)(dian)(dian)(dian)池(chi)平臺電(dian)(dian)(dian)(dian)壓(ya)(ya)為(wei)(wei)3.7V，充滿電(dian)(dian)(dian)(dian)后為(wei)(wei)4.2V，電(dian)(dian)(dian)(dian)芯放電(dian)(dian)(dian)(dian)截止電(dian)(dian)(dian)(dian)壓(ya)(ya)為(wei)(wei)2.7V，相比之(zhi)下鋰(li)(li)電(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)壓(ya)(ya)要高(gao)于動力電(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)壓(ya)(ya)；磷(lin)酸(suan)(suan)(suan)鐵(tie)(tie)鋰(li)(li)耐(nai)過(guo)充過(guo)放，短(duan)時(shi)過(guo)放到(dao)(dao)0都(dou)能恢復80%以(yi)上；鋰(li)(li)離子電(dian)(dian)(dian)(dian)池(chi)過(guo)放到(dao)(dao)2.5V以(yi)下時(shi)就會產生不可逆損壞。

3、動力鋰電(dian)池穿刺不起火不爆(bao)(bao)炸，但是(shi)正常的(de)鋰電(dian)池針刺時會(hui)爆(bao)(bao)炸。

4、磷酸(suan)鐵(tie)鋰(li)(li)動力電(dian)池耐(nai)過充到100%都不會起火爆炸；普通鋰(li)(li)電(dian)池達到規定數值就會析氣鼓脹。

5、動(dong)力(li)鋰電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)和(he)普通鋰電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)區別放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)方面：磷(lin)(lin)酸鐵鋰動(dong)力(li)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)可以支(zhi)持持續(xu)30C放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)倍率而且不會發生安(an)全(quan)隱患(huan)，有的磷(lin)(lin)酸鐵鋰電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)瞬(shun)間電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)可以達到600A，而普通鋰電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)正常(chang)支(zhi)持3C放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)倍率，持續(xu)大電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)會發生電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)假死現(xian)象。

6、磷酸(suan)鐵鋰(li)動(dong)力(li)電池和鋰(li)電池的重(zhong)量區(qu)別：同等體積(ji)的磷酸(suan)鐵鋰(li)動(dong)力(li)電池要比普通鋰(li)電池重(zhong)量重(zhong)近(jin)一倍。

7、從內阻分析動(dong)力(li)(li)電池(chi)和鋰電池(chi)的區別：同(tong)等(deng)體積的磷酸鐵鋰動(dong)力(li)(li)電池(chi)要(yao)比普(pu)通鋰電池(chi)內阻小很多。

8、動力鋰(li)(li)電池(chi)(chi)和普通鋰(li)(li)電池(chi)(chi)區別容量：同等體積的(de)(de)磷酸鐵(tie)(tie)鋰(li)(li)動力電池(chi)(chi)要比普通鋰(li)(li)電池(chi)(chi)容量低，即磷酸鐵(tie)(tie)鋰(li)(li)正極材料(liao)做(zuo)出(chu)來的(de)(de)電池(chi)(chi)能量密(mi)度要比普通鋰(li)(li)電池(chi)(chi)能量密(mi)度低60%左右。

9、磷酸鐵鋰(li)動(dong)(dong)力電(dian)池(chi)和鋰(li)電(dian)池(chi)的價(jia)(jia)格(ge)區別：磷酸鐵鋰(li)動(dong)(dong)力電(dian)池(chi)價(jia)(jia)格(ge)要比普通鋰(li)電(dian)池(chi)價(jia)(jia)格(ge)貴50%左右。

10、磷(lin)酸(suan)鐵鋰(li)(li)動力電(dian)池(chi)和鋰(li)(li)電(dian)池(chi)的工作(zuo)(zuo)溫度區別：磷(lin)酸(suan)鐵鋰(li)(li)動力電(dian)池(chi)與(yu)鋰(li)(li)電(dian)池(chi)工作(zuo)(zuo)溫度相(xiang)(xiang)比，磷(lin)酸(suan)鐵鋰(li)(li)工作(zuo)(zuo)環(huan)境(jing)溫度要(yao)高(gao)一些(xie)，而鋰(li)(li)電(dian)池(chi)工作(zuo)(zuo)環(huan)境(jing)溫度要(yao)相(xiang)(xiang)對低5度左右(you)。

動力鋰(li)(li)電(dian)(dian)池(chi)和普通鋰(li)(li)電(dian)(dian)池(chi)區(qu)別對(dui)比不同之(zhi)處(chu)究竟在哪里，調查分(fen)(fen)析發(fa)現最主要的(de)區(qu)別在電(dian)(dian)池(chi)材料選(xuan)(xuan)型(xing)(xing)和放(fang)電(dian)(dian)倍率應用方(fang)面，不同的(de)鋰(li)(li)電(dian)(dian)池(chi)正極材料在應用方(fang)面有所不同，而如果放(fang)電(dian)(dian)倍率不同，那么就會更(geng)容(rong)易細分(fen)(fen)一些(xie)應用場景，只有了解了這些(xie)動力鋰(li)(li)電(dian)(dian)池(chi)和普通鋰(li)(li)電(dian)(dian)池(chi)的(de)區(qu)別才(cai)能更(geng)好(hao)的(de)使用做電(dian)(dian)池(chi)選(xuan)(xuan)型(xing)(xing)與方(fang)案設計。
