電(dian)(dian)池的(de)修(xiu)復雖然沒有成為(wei)一個行(xing)業，但是電(dian)(dian)池修(xiu)復工作一直是存在的(de)。不(bu)少(shao)電(dian)(dian)池制造商對保用(yong)期以(yi)內的(de)返退電(dian)(dian)池采(cai)取(qu)"修(xiu)舊(jiu)利舊(jiu)"的(de)發生(sheng)，把通過(guo)維(wei)修(xiu)的(de)電(dian)(dian)池重(zhong)新提供給用(yong)戶，以(yi)提高電(dian)(dian)池的(de)有效(xiao)使用(yong)壽命，降低報廢率，減少(shao)電(dian)(dian)池制造商的(de)部分理索賠的(de)損失。這些修(xiu)復方法(fa)為(wei)：

1、重新配組
電池返退以后，電池制造商重新進行充放(fang)電(dian)檢驗(yan)，在檢驗(yan)中往往會發現有50％以上的電(dian)池(chi)(chi)不符(fu)合返退(tui)條(tiao)件的電(dian)池(chi)(chi)。其原(yuan)因也就是在串連電(dian)池(chi)(chi)組中，個別的電(dian)池(chi)(chi)落后(hou)形成整組電(dian)池(chi)(chi)功能下降而(er)引起(qi)整組返退(tui)。

2、補水
鑒于(yu)部分電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)制造(zao)商還是(shi)采用(yong)(yong)低銻合金的(de)板柵，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)失(shi)(shi)水(shui)(shui)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)平比(bi)較低，加上(shang)最高(gao)充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓高(gao)于(yu)析氫電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)失(shi)(shi)水(shui)(shui)更加嚴重，形成(cheng)了電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)第一位的(de)失(shi)(shi)效原因。對(dui)此(ci)，一些電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)制造(zao)商有(you)意(yi)的(de)改造(zao)了蓋板，并且在排氣閥下部設立了螺裝結(jie)構，為打(da)開電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)形成(cheng)了方便條件，這樣(yang)，有(you)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)制造(zao)商開展(zhan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)補水(shui)(shui)工作(zuo)。對(dui)使用(yong)(yong)了半年的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)進行一次(ci)補水(shui)(shui)，可以(yi)延長電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)使用(yong)(yong)壽(shou)命，延長時間平均達到(dao)3個月以(yi)上(shang)。應該注(zhu)意(yi)的(de)是(shi)，每次(ci)補水(shui)(shui)以(yi)后，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)都利用(yong)(yong)處于(yu)過充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)狀態把電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)由"準貧(pin)液"轉(zhuan)為"貧(pin)液"狀態，而這個過充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)對(dui)提高(gao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)容量是(shi)有(you)好處的(de)。

3、消除硫化
采(cai)用專門的(de)(de)設備，對(dui)電(dian)池(chi)(chi)進(jin)行消(xiao)除硫化(hua)的(de)(de)處理。這(zhe)里主(zhu)要有(you)2種(zhong)(zhong)方(fang)(fang)法(fa)(fa)，其一就是(shi)(shi)高電(dian)壓大(da)電(dian)流脈沖充電(dian)，通過負阻擊穿消(xiao)除硫化(hua)。這(zhe)種(zhong)(zhong)方(fang)(fang)法(fa)(fa)速度(du)快(kuai)，見效快(kuai)，但是(shi)(shi)對(dui)電(dian)池(chi)(chi)的(de)(de)壽命影響比較大(da)。另(ling)外(wai)的(de)(de)方(fang)(fang)法(fa)(fa)就是(shi)(shi)采(cai)用小電(dian)流頻(pin)率高達(da)8KHz以上，利用大(da)結晶(jing)諧振的(de)(de)方(fang)(fang)法(fa)(fa)來溶解(jie)，這(zhe)種(zhong)(zhong)方(fang)(fang)法(fa)(fa)修復(fu)(fu)比較慢，修復(fu)(fu)效果也(ye)比較好，但是(shi)(shi)，修復(fu)(fu)時間比較長，往往在120小時以上。實際(ji)測試(shi)數據表(biao)明，對(dui)于補水(shui)以后沒有(you)達(da)到60％補充容(rong)量的(de)(de)電(dian)池(chi)(chi)進(jin)行除硫處理，還有(you)約2/3的(de)(de)電(dian)池(chi)(chi)可以達(da)到60％以上的(de)(de)容(rong)量，甚至還有(you)35％以上的(de)(de)電(dian)池(chi)(chi)的(de)(de)容(rong)量可以達(da)到80％以上的(de)(de)容(rong)量。

4、采取類似電(dian)霸、保護器類的(de)(de)脈沖發生器并聯在電(dian)池(chi)上，對(dui)電(dian)池(chi)進行脈沖維護。這種方法對(dui)修(xiu)復電(dian)池(chi)比(bi)較慢，但是由于(yu)長年在維修(xiu)，所以，如果沒有過放電(dian)，對(dui)于(yu)連續(xu)使用的(de)(de)電(dian)池(chi)來說(shuo)，往往是徹底消除(chu)了電(dian)池(chi)硫化的(de)(de)可能性。

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(jun)壽(shou)命會大(da)(da)大(da)(da)提高。定期檢修(xiu)的(de)(de)意(yi)義(yi)比較大(da)(da)，不(bu)要等電(dian)池由于(yu)失水和(he)硫化的(de)(de)影響(xiang)，損傷正極(ji)板(ban)以(yi)(yi)后再修(xiu)復。這樣(yang)，可以(yi)(yi)大(da)(da)大(da)(da)延長電(dian)池的(de)(de)壽(shou)命。而一旦(dan)電(dian)池出現嚴重的(de)(de)失水和(he)硫化以(yi)(yi)后，對正極(ji)板(ban)的(de)(de)損傷相(xiang)對也比較大(da)(da)。所(suo)以(yi)(yi)，應該在對正極(ji)板(ban)損傷以(yi)(yi)前(qian)久對電(dian)池進行(xing)適(shi)當的(de)(de)維修(xiu)。采取防(fang)患于(yu)未然的(de)(de)檢修(xiu)的(de)(de)方法比亡羊補牢的(de)(de)方法更加有效。
