太陽能蓄電池是太(tai)陽能(neng)路燈中的關鍵零配件，現階段選用的有鉛酸電池、膠體電池、三元鋰電池和磷酸鐵鋰電池充電電池4種，4種太陽能路燈常見充電電池，哪樣充電電池才算是好的呢?我們一起來看一下這4種充電電池的特性：　　
1、鉛酸電(dian)池(chi)：鉛酸電(dian)池(chi)的極片是由(you)鉛和(he)鉛的金屬氧化物(wu)組成，鋰電(dian)池(chi)電(dian)解液是鹽酸的溶液。鉛酸電(dian)池(chi)的關鍵優勢是工作電(dian)壓相(xiang)(xiang)對性較(jiao)平(ping)穩，價錢較(jiao)為(wei)劃算(suan);缺陷是比能相(xiang)(xiang)對性較(jiao)低，因此 容(rong)積(ji)要比一(yi)(yi)般充電(dian)電(dian)池(chi)大(da)許(xu)多 ，鉛酸電(dian)池(chi)的使用期較(jiao)為(wei)短，一(yi)(yi)般300-500次深循環系統，維(wei)護保養起來較(jiao)為(wei)經常，但由(you)于品(pin)牌優勢，在太陽能路燈制造行業仍在很多應用。

2、膠體(ti)電(dian)池(chi)(chi)(chi)：等于是(shi)(shi)鉛酸電(dian)池(chi)(chi)(chi)的(de)全新升級(ji)(ji)，它免維護(hu)保養，解決了(le)鉛酸電(dian)池(chi)(chi)(chi)維護(hu)保養經常的(de)抨擊(ji)，內部將膠體(ti)溶液鋰(li)電(dian)池(chi)(chi)(chi)電(dian)解液替代了(le)鹽(yan)酸鋰(li)電(dian)池(chi)(chi)(chi)電(dian)解液，在儲電(dian)量、充放電(dian)量、安(an)全系數及其(qi)使(shi)用(yong)(yong)壽命(ming)層(ceng)面(mian)都(dou)逐步提高，但在價(jia)錢層(ceng)面(mian)有時(shi)候乃至迎頭趕上三(san)元鋰(li)電(dian)池(chi)(chi)(chi)。膠體(ti)電(dian)池(chi)(chi)(chi)可在-40℃——65℃的(de)溫度范圍內應(ying)用(yong)(yong)，超低溫特性(xing)(xing)比較好，能夠在北(bei)方(fang)地區嚴寒地域應(ying)用(yong)(yong)。抗震(zhen)等級(ji)(ji)特性(xing)(xing)好，能在各(ge)種各(ge)樣極端的(de)標準下安(an)全性(xing)(xing)應(ying)用(yong)(yong)。使(shi)用(yong)(yong)期是(shi)(shi)一般鉛酸電(dian)池(chi)(chi)(chi)的(de)一倍(bei)乃至也要多。

3、三元鋰(li)電(dian)池(chi)：三元鋰(li)電(dian)池(chi)的(de)(de)優(you)勢許多 ，它(ta)比性能(neng)高、體型小、電(dian)池(chi)充(chong)電(dian)快、價錢高。它(ta)深循環系統頻次約(yue)在500-800次，使(shi)用(yong)壽命和膠體電(dian)池(chi)類似，應(ying)用(yong)的(de)(de)溫(wen)度(du)范圍(wei)在-15℃-45℃。但三元鋰(li)電(dian)池(chi)也存有缺點，它(ta)的(de)(de)充(chong)電(dian)電(dian)池(chi)內部不(bu)太(tai)平穩(wen)，如(ru)果是不(bu)過關的(de)(de)廠家生(sheng)產的(de)(de)三元鋰(li)電(dian)池(chi)，有可能(neng)在過度(du)充(chong)電(dian)全過程或是溫(wen)度(du)較高的(de)(de)自然環境下，都(dou)是有將會發(fa)生(sheng)爆(bao)炸事故狀況。

4、磷(lin)(lin)酸(suan)鐵(tie)鋰(li)(li)電(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)：磷(lin)(lin)酸(suan)鐵(tie)鋰(li)(li)電(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)是集諸多優勢為(wei)一(yi)體的(de)電(dian)(dian)(dian)瓶(ping)，它比能較高(gao)、體型小、電(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)快、使用期長、可(ke)靠性佳，但(dan)價錢是全部充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)中高(gao)的(de)。它深循環系統(tong)電(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)頻(pin)次一(yi)般(ban)在1500-2000次，一(yi)組磷(lin)(lin)酸(suan)鐵(tie)鋰(li)(li)電(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)在一(yi)切(qie)正常應(ying)用的(de)狀(zhuang)況下，一(yi)般(ban)可(ke)以用8-10年，能夠在-40℃-70℃的(de)自然環境下開展(zhan)應(ying)用，應(ying)用的(de)溫度范(fan)圍還是較為(wei)廣的(de)。

由以上比照能夠得到，太陽能路燈中(zhong)應(ying)用(yong)磷酸(suan)鐵(tie)(tie)鋰電(dian)(dian)(dian)(dian)池(chi)充電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)好，可是價錢相(xiang)對(dui)性較高。現階段(duan)磷酸(suan)鐵(tie)(tie)鋰電(dian)(dian)(dian)(dian)池(chi)充電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)是中(zhong)國(guo)產(chan)(chan)品研發、具備完善和(he)自立自強(qiang)產(chan)(chan)權年限的動力電(dian)(dian)(dian)(dian)池(chi)，太陽能路(lu)燈生產(chan)(chan)商(shang)許多 ，應(ying)用(yong)標準(zhun)和(he)安全(quan)防范也都做得(de)很(hen)健全(quan)，因此(ci)應(ying)用(yong)磷酸(suan)鐵(tie)(tie)鋰電(dian)(dian)(dian)(dian)池(chi)充電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)是好的挑選。
