一、鋰電池和鉛酸蓄電池的區別

1、安全對比

動力型鋰(li)(li)電池(chi)（錳酸(suan)鋰(li)(li)、磷(lin)酸(suan)鐵鋰(li)(li)）材(cai)料不同(tong)安全性(xing)有所差別，鉛(qian)酸(suan)電池(chi)技術已經相當成(cheng)熟(shu)，安全性(xing)比鋰(li)(li)電池(chi)高(gao)。

2、環保對比

鋰電(dian)池(chi)沒有(you)污(wu)染，而鉛(qian)(qian)酸(suan)電(dian)池(chi)有(you)重金屬鉛(qian)(qian)的污(wu)染。所以使(shi)用鉛(qian)(qian)酸(suan)電(dian)池(chi)的電(dian)動汽車還是(shi)會污(wu)染環境。

3、價格對比

市場上相同容量的品牌鋰電池價(jia)格(ge)是(shi)鉛酸電(dian)(dian)池(chi)的一倍多。這就是(shi)使用鋰(li)電(dian)(dian)池(chi)的電(dian)(dian)動汽車價(jia)格(ge)比較貴的原因。

4、能量對比

鋰電池的質量比、體(ti)積比、能量比都(dou)高(gao)于鉛酸電池大(da)概約40%。

5、自放電率對比

鋰電池月(yue)自放電小于3%，而鉛(qian)酸電池15~30%，差(cha)別(bie)較大。

6、使用壽命對比

目(mu)前通用(yong)的磷酸(suan)鐵鋰充(chong)電(dian)1500次(ci)，沒有記憶(yi)效應(ying)，充(chong)電(dian)1500次(ci)后約85%的存儲能力，而鉛酸(suan)電(dian)池為(wei)500次(ci)左(zuo)右，存儲能力也會大幅(fu)下降，而且記憶(yi)效應(ying)很明顯。所以使(shi)用(yong)鋰電(dian)池的電(dian)動汽車電(dian)池使(shi)用(yong)壽命(ming)會更(geng)長。

7、電壓平臺對比

鋰(li)電(dian)池電(dian)壓平臺都大于(yu)3V，鉛酸電(dian)池是2V。

8、放電特性對比

簡單的(de)(de)說(shuo)同樣容量的(de)(de)電(dian)(dian)(dian)(dian)(dian)池(chi)，大(da)電(dian)(dian)(dian)(dian)(dian)流放(fang)電(dian)(dian)(dian)(dian)(dian)的(de)(de)情況(kuang)下，鋰電(dian)(dian)(dian)(dian)(dian)池(chi)要比鉛(qian)酸電(dian)(dian)(dian)(dian)(dian)池(chi)多放(fang)出來約30%的(de)(de)電(dian)(dian)(dian)(dian)(dian)。

9、耐用性方面

鋰電(dian)(dian)(dian)(dian)池(chi)(chi)耐用性(xing)較強(qiang)，耐震動(dong)性(xing)好，完全(quan)(quan)充電(dian)(dian)(dian)(dian)狀態(tai)的電(dian)(dian)(dian)(dian)池(chi)(chi)安全(quan)(quan)固(gu)定，消耗慢，充放超過(guo)500次，并且(qie)無記(ji)憶(yi)，一般(ban)(ban)壽命在4—5年(nian)。鉛酸電(dian)(dian)(dian)(dian)池(chi)(chi)一般(ban)(ban)在深充深放電(dian)(dian)(dian)(dian)400次以內，有記(ji)憶(yi)，壽命在兩年(nian)左右(you)。如(ru)果使用的是(shi)(shi)免(mian)維護(hu)鉛酸蓄電(dian)(dian)(dian)(dian)池(chi)(chi)，需要注意的是(shi)(shi)其電(dian)(dian)(dian)(dian)池(chi)(chi)失水量少，使用中一般(ban)(ban)不需添加蒸餾水。

二、電動車鋰電池和鉛酸蓄電池哪種好

1、鉛酸電池優缺點

性價比高：一般認為(wei)電動(dong)車用鉛酸(suan)電池(chi)(chi)(chi)比鋰(li)電池(chi)(chi)(chi)要好，主(zhu)要是(shi)因(yin)為(wei)鉛酸(suan)電池(chi)(chi)(chi)更(geng)安全，價格相(xiang)對便宜(yi)，大眾更(geng)容易接受，最重要的(de)是(shi)鉛酸(suan)電池(chi)(chi)(chi)回(hui)收(shou)價格比鋰(li)電池(chi)(chi)(chi)更(geng)高。

高倍率(lv)放電(dian)(dian)(dian)性能(neng)(neng)更好：一般(ban)來說(shuo)，一組鉛(qian)酸(suan)電(dian)(dian)(dian)池(chi)(chi)只(zhi)要幾(ji)百(bai)塊，一組鋰電(dian)(dian)(dian)池(chi)(chi)，隨(sui)隨(sui)便便的(de)就要一千多(duo)近兩千塊。鉛(qian)酸(suan)電(dian)(dian)(dian)池(chi)(chi)過載能(neng)(neng)力(li)和(he)抗沖擊(ji)能(neng)(neng)力(li)強，電(dian)(dian)(dian)動(dong)車行駛中的(de)阻力(li)，隨(sui)時(shi)變換，甚至(zhi)突然被停止，這時(shi)電(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)流變化很大(da)的(de)，在打火那幾(ji)秒鐘，電(dian)(dian)(dian)流達兩三百(bai)安培，鉛(qian)酸(suan)電(dian)(dian)(dian)池(chi)(chi)能(neng)(neng)安然無恙，而鋰電(dian)(dian)(dian)池(chi)(chi)則是難望其項背(bei)。

鉛(qian)酸電(dian)池(chi)(chi)(chi)也(ye)有缺點：比如重金屬(shu)容易造成環境污染；與(yu)鋰(li)電(dian)池(chi)(chi)(chi)相(xiang)比，鉛(qian)酸電(dian)池(chi)(chi)(chi)能(neng)量(liang)密度更低；而(er)且其使用壽(shou)命不(bu)及鋰(li)電(dian)池(chi)(chi)(chi)。

2、鋰電池優缺點

能效高(gao)：鋰電池(chi)無論是(shi)(shi)體積比(bi)(bi)能量，還是(shi)(shi)重量比(bi)(bi)能量，鋰電池(chi)均比(bi)(bi)鉛酸蓄電池(chi)高(gao)出3倍以上(shang)。鋰電池(chi)體積更小、重量更輕、循環壽(shou)命長。

輕(qing)便環保：鋰電(dian)池相對(dui)輕(qing)巧，攜帶方(fang)便，而壽命(ming)相對(dui)要長很多(duo)。此(ci)外(wai)，鋰電(dian)池的高低溫(wen)適應(ying)性更強，受溫(wen)度影(ying)響因素(su)較小(xiao)，且更加綠色環保。

鋰電(dian)(dian)池(chi)也有三個(ge)缺點：其安全穩定(ding)性相對而言比較差(cha)，要是操(cao)作不當，很容易發生爆炸的(de)風(feng)險。另外，鋰電(dian)(dian)池(chi)不能大電(dian)(dian)流(liu)放電(dian)(dian)且生產要求條件(jian)高，成本更高。

以目(mu)前(qian)而(er)言，鋰(li)(li)(li)電(dian)(dian)(dian)車(che)(che)市場普及率低于(yu)鉛酸(suan)(suan)電(dian)(dian)(dian)池(chi)車(che)(che)，其主(zhu)要的(de)因素是(shi)技(ji)術(shu)的(de)不(bu)(bu)完善，鋰(li)(li)(li)電(dian)(dian)(dian)池(chi)成(cheng)本仍相對偏高。因此在現(xian)有(you)“鋰(li)(li)(li)電(dian)(dian)(dian)車(che)(che)”產(chan)(chan)品設計中(zhong)，多采用減少鋰(li)(li)(li)電(dian)(dian)(dian)池(chi)的(de)容量配置，來相應降低整車(che)(che)實施(shi)成(cheng)本，而(er)這(zhe)使得現(xian)有(you)“鋰(li)(li)(li)電(dian)(dian)(dian)車(che)(che)”產(chan)(chan)品之車(che)(che)型(xing)過于(yu)單一化。比(bi)如(ru)，目(mu)前(qian)市面上鋰(li)(li)(li)電(dian)(dian)(dian)產(chan)(chan)品多為“電(dian)(dian)(dian)單車(che)(che)”而(er)且續(xu)程不(bu)(bu)是(shi)很遠的(de)車(che)(che)型(xing)，但是(shi)像四(si)輪電(dian)(dian)(dian)動(dong)車(che)(che)，四(si)輪老人電(dian)(dian)(dian)動(dong)代(dai)步(bu)車(che)(che)這(zhe)些比(bi)較(jiao)遠續(xu)程的(de)就目(mu)前(qian)情況還是(shi)比(bi)較(jiao)適(shi)合“鉛酸(suan)(suan)電(dian)(dian)(dian)池(chi)”。總之鉛酸(suan)(suan)電(dian)(dian)(dian)池(chi)和鋰(li)(li)(li)電(dian)(dian)(dian)池(chi)哪個好，不(bu)(bu)能單純(chun)的(de)以電(dian)(dian)(dian)池(chi)的(de)質量好壞而(er)論，二者各具優劣(lie)，適(shi)應于(yu)不(bu)(bu)同的(de)需求(qiu)人群(qun)，消費(fei)者應根(gen)據自己需求(qiu)選擇。
