電(dian)(dian)(dian)池(chi)的(de)(de)(de)修(xiu)復雖然沒有(you)成(cheng)為(wei)一個行業(ye)，但是電(dian)(dian)(dian)池(chi)修(xiu)復工作一直是存在的(de)(de)(de)。不(bu)少電(dian)(dian)(dian)池(chi)制(zhi)造(zao)商(shang)(shang)對(dui)保用期以(yi)內(nei)的(de)(de)(de)返退(tui)電(dian)(dian)(dian)池(chi)采取"修(xiu)舊(jiu)利(li)舊(jiu)"的(de)(de)(de)發生，把通(tong)過維修(xiu)的(de)(de)(de)電(dian)(dian)(dian)池(chi)重(zhong)新提(ti)供給用戶，以(yi)提(ti)高電(dian)(dian)(dian)池(chi)的(de)(de)(de)有(you)效使用壽(shou)命，降低(di)報廢率，減少電(dian)(dian)(dian)池(chi)制(zhi)造(zao)商(shang)(shang)的(de)(de)(de)部分(fen)理(li)索賠的(de)(de)(de)損失。這些(xie)修(xiu)復方法為(wei)：

1、重新配組
電池返退以后，電池制造商重新(xin)進行充(chong)放電(dian)檢驗，在(zai)檢驗中往往會發現有(you)50％以(yi)上的(de)電(dian)池(chi)(chi)不符合返退條件的(de)電(dian)池(chi)(chi)。其原因也就是在(zai)串連電(dian)池(chi)(chi)組中，個別的(de)電(dian)池(chi)(chi)落后形成整組電(dian)池(chi)(chi)功能下降(jiang)而引起整組返退。

2、補水
鑒于部分(fen)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)制(zhi)造(zao)(zao)商還是(shi)采(cai)用(yong)(yong)低銻(ti)合金的板柵，電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)失水電(dian)(dian)(dian)(dian)(dian)(dian)平比較低，加上(shang)最高(gao)充電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)高(gao)于析氫電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)，電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)失水更(geng)加嚴重(zhong)，形成(cheng)了(le)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)的第一(yi)位的失效原因。對(dui)此，一(yi)些電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)制(zhi)造(zao)(zao)商有(you)(you)意(yi)的改(gai)造(zao)(zao)了(le)蓋板，并(bing)且在排氣閥下部設立了(le)螺裝結構，為打開電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)形成(cheng)了(le)方便條件，這樣，有(you)(you)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)制(zhi)造(zao)(zao)商開展(zhan)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)補(bu)水工作。對(dui)使用(yong)(yong)了(le)半(ban)年的電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)進(jin)行一(yi)次補(bu)水，可以(yi)延長電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)的使用(yong)(yong)壽命，延長時間平均達到(dao)3個(ge)月(yue)以(yi)上(shang)。應(ying)該注意(yi)的是(shi)，每次補(bu)水以(yi)后，電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)都利用(yong)(yong)處(chu)于過(guo)充電(dian)(dian)(dian)(dian)(dian)(dian)狀態把電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)由(you)"準(zhun)貧液"轉為"貧液"狀態，而這個(ge)過(guo)充電(dian)(dian)(dian)(dian)(dian)(dian)對(dui)提高(gao)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)容量(liang)是(shi)有(you)(you)好處(chu)的。

3、消除硫化
采用(yong)(yong)專門的(de)(de)(de)設備，對電(dian)(dian)池(chi)(chi)進(jin)行(xing)消(xiao)除(chu)硫化(hua)的(de)(de)(de)處理(li)。這里(li)主要有(you)2種方法(fa)，其一就(jiu)是(shi)高(gao)電(dian)(dian)壓大電(dian)(dian)流脈沖充(chong)電(dian)(dian)，通過負(fu)阻擊穿(chuan)消(xiao)除(chu)硫化(hua)。這種方法(fa)速度快，見效(xiao)快，但是(shi)對電(dian)(dian)池(chi)(chi)的(de)(de)(de)壽命影響比(bi)較(jiao)大。另外的(de)(de)(de)方法(fa)就(jiu)是(shi)采用(yong)(yong)小電(dian)(dian)流頻率高(gao)達8KHz以(yi)上，利用(yong)(yong)大結晶(jing)諧振的(de)(de)(de)方法(fa)來(lai)溶(rong)解(jie)，這種方法(fa)修(xiu)(xiu)復(fu)比(bi)較(jiao)慢，修(xiu)(xiu)復(fu)效(xiao)果也比(bi)較(jiao)好，但是(shi)，修(xiu)(xiu)復(fu)時(shi)間比(bi)較(jiao)長，往往在120小時(shi)以(yi)上。實際(ji)測試數據表明，對于補水以(yi)后(hou)沒有(you)達到(dao)60％補充(chong)容(rong)量(liang)的(de)(de)(de)電(dian)(dian)池(chi)(chi)進(jin)行(xing)除(chu)硫處理(li)，還有(you)約2/3的(de)(de)(de)電(dian)(dian)池(chi)(chi)可以(yi)達到(dao)60％以(yi)上的(de)(de)(de)容(rong)量(liang)，甚(shen)至還有(you)35％以(yi)上的(de)(de)(de)電(dian)(dian)池(chi)(chi)的(de)(de)(de)容(rong)量(liang)可以(yi)達到(dao)80％以(yi)上的(de)(de)(de)容(rong)量(liang)。

4、采取類(lei)似電(dian)霸、保護(hu)器類(lei)的(de)(de)脈沖發生(sheng)器并聯在電(dian)池(chi)(chi)上，對(dui)(dui)電(dian)池(chi)(chi)進行脈沖維護(hu)。這種方法對(dui)(dui)修(xiu)復(fu)電(dian)池(chi)(chi)比較慢，但是由于長年在維修(xiu)，所(suo)以，如(ru)果沒(mei)有過放電(dian)，對(dui)(dui)于連(lian)續(xu)使用的(de)(de)電(dian)池(chi)(chi)來說，往(wang)往(wang)是徹底消除了電(dian)池(chi)(chi)硫化的(de)(de)可(ke)能性。

5、綜合修復方法
如果對電池采用定期檢驗，及時除硫和補水，單只電池充電、重新配組。采取這些做法以后，電池的(de)(de)平均壽(shou)命(ming)會大大提高。定期檢修(xiu)的(de)(de)意(yi)義比較(jiao)大，不要等電(dian)池由于失(shi)水(shui)和硫(liu)化的(de)(de)影響(xiang)，損傷(shang)正(zheng)(zheng)極板以(yi)(yi)后再修(xiu)復。這樣，可(ke)以(yi)(yi)大大延長電(dian)池的(de)(de)壽(shou)命(ming)。而(er)一旦電(dian)池出現(xian)嚴重(zhong)的(de)(de)失(shi)水(shui)和硫(liu)化以(yi)(yi)后，對(dui)(dui)正(zheng)(zheng)極板的(de)(de)損傷(shang)相對(dui)(dui)也比較(jiao)大。所以(yi)(yi)，應(ying)該在(zai)對(dui)(dui)正(zheng)(zheng)極板損傷(shang)以(yi)(yi)前久對(dui)(dui)電(dian)池進行適當(dang)的(de)(de)維(wei)修(xiu)。采取防患于未(wei)然(ran)的(de)(de)檢修(xiu)的(de)(de)方(fang)法比亡(wang)羊補牢的(de)(de)方(fang)法更加有效。
