一、18650鋰電池是什么意思

18650這(zhe)幾個(ge)數字，代表(biao)外表(biao)尺寸：18指電池直徑18.0mm，650指電池高度65.0mm。常見的18650電(dian)(dian)(dian)池分為(wei)(wei)鋰(li)離子電(dian)(dian)(dian)池、磷(lin)酸(suan)鐵鋰(li)和鎳(nie)氫電(dian)(dian)(dian)池。電(dian)(dian)(dian)壓及(ji)容(rong)量規(gui)格為(wei)(wei)鎳(nie)氫電(dian)(dian)(dian)池電(dian)(dian)(dian)壓為(wei)(wei)1.2V常見(jian)容(rong)量(liang)為2500MAH，鋰離子電池電壓為3.6V常見容量為1500MAH-3100MAH。

18650鋰電池電壓

常見的可充18650鋰(li)電池(chi)，電壓都是標(biao)3.6或(huo)者3.7v,充滿電的時候是4.2v，這跟電量（容(rong)量）關(guan)系不大，18650電池主流的容量從1800mAh到2600mAh，（18650動(dong)力電池容量多(duo)在1200~1600mAh），主流的容(rong)量甚至有標3500或4000mAh以(yi)上(shang)的都有（提醒(xing)大家，3100mAh以上的18650如(ru)果是國(guo)產的(de)話那基本(ben)上可認為是假的(de)，目前(qian)量產了的(de)最大容(rong)量為3400mAh）。

18650鋰電(dian)池(chi)用途

18650電(dian)(dian)池壽(shou)命理論為循環充電(dian)(dian)1000次(ci)。由于單位密度的(de)容量很大(da)，所以常用(yong)于大(da)部份用(yong)于筆記本電池，除此之外(wai)，因(yin)18650在(zai)工作(zuo)中的穩定性能非(fei)常好，廣(guang)泛(fan)應用于各大電子領域(yu)：常用于高檔(dang)強光手(shou)電(dian)、隨身電(dian)源,無(wu)線數據(ju)傳(chuan)輸器(qi)，電熱保暖衣、鞋，便(bian)攜式(shi)儀(yi)器(qi)儀(yi)表(biao)，便(bian)攜式(shi)照明設備，便(bian)攜式(shi)打印機，工業(ye)儀(yi)器(qi)，醫療儀(yi)器(qi)等。

18650鋰電(dian)池區別

一般18650的電(dian)池(chi)在工業上用的比較(jiao)多(duo)，民用的很少，常見的也就在筆記(ji)本電(dian)池(chi)和高(gao)檔手電(dian)上用的比較(jiao)多(duo)。

18650鋰(li)電池型號

18650只是電池的尺寸(cun)型號，根據電池種類還能分為，鋰(li)離子的18650，磷酸(suan)鐵鋰的18650，鎳氫的18650（很少見），常見的18650是鋰離子的(de)。

二、18650鋰電(dian)池修復方法介紹

1、鋰(li)電池修復方(fang)法一：

用(yong)橡皮檫或其他清潔工具可擦除表面的(de)生銹物質。

鋰電(dian)池修復方(fang)法一原理(li)：

長時間(jian)(jian)使(shi)用的(de)鋰(li)電池(chi)(chi)的(de)金(jin)屬表(biao)面(mian)會有(you)一定程度的(de)氧化，導(dao)致手機電池(chi)(chi)跟手機接(jie)觸(chu)不好，鋰(li)電池(chi)(chi)使(shi)用時間(jian)(jian)變短，而用橡皮檫或其他清(qing)潔工(gong)具可擦除表(biao)面(mian)的(de)生銹物質，讓(rang)電池(chi)(chi)與手機接(jie)觸(chu)變好。

2、鋰電池修復方法二：

將你的電(dian)(dian)池(chi)全部(bu)用(yong)完后取(qu)下來，用(yong)溫度(du)處理，電(dian)(dian)池(chi)在溫度(du)不(bu)穩定的情(qing)況下會大大的縮短(duan)使(shi)用(yong)時(shi)間，因為電(dian)(dian)池(chi)是沒有(you)電(dian)(dian)的并且相(xiang)當一(yi)部(bu)分鋰(li)離子已經帶有(you)記憶電(dian)(dian)了(le)用(yong)這樣的方法可以使(shi)記憶電(dian)(dian)釋放(fang)一(yi)部(bu)分，冬天到了(le)，放(fang)到外(wai)面一(yi)會，再(zai)拿到屋里(li)。

鋰電(dian)池修(xiu)復(fu)方(fang)法二的原(yuan)理：

低(di)(di)溫(wen)能使鋰電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)內部(bu)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)解(jie)液發生變化，促進剛剛經(jing)過(guo)冷凍的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)發生化學(xue)反應。鋰電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)(de)使用過(guo)程(cheng)(cheng)其實是一個充(chong)(chong)放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)過(guo)程(cheng)(cheng)。在這期間(jian)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)內的(de)(de)(de)陰電(dian)(dian)(dian)(dian)(dian)(dian)(dian)荷和(he)陽電(dian)(dian)(dian)(dian)(dian)(dian)(dian)荷相互交撞。電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)之所(suo)以會越(yue)來越(yue)不經(jing)用，是因(yin)(yin)為在正(zheng)常的(de)(de)(de)室溫(wen)下(xia)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子內部(bu)的(de)(de)(de)動(dong)能比較大，因(yin)(yin)而(er)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)處于活(huo)躍狀態，漏(lou)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)情(qing)況相對頻繁。而(er)將鋰電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)放入低(di)(di)溫(wen)環(huan)境里(li)，鋰電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)表面的(de)(de)(de)鋰膜與電(dian)(dian)(dian)(dian)(dian)(dian)(dian)解(jie)液的(de)(de)(de)微(wei)觀結構，以及它們的(de)(de)(de)交界面都會發生明顯變化，導致電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)內部(bu)暫不活(huo)躍，漏(lou)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流減少。所(suo)以再次充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)后，手(shou)機的(de)(de)(de)待(dai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)時間(jian)會增加。

3、鋰電池修復方法三：

還有一種方(fang)法，取(qu)下電池(chi)，放一周左(zuo)右，將(jiang)(jiang)電慢慢的消耗，需要先(xian)用機器將(jiang)(jiang)電完全(quan)消耗之后。然(ran)后再全(quan)沖，估記你(ni)現在的充(chong)電時(shi)間肯定很短(duan)了，沖滿(man)后，斷開再沖，反復幾(ji)次，絕(jue)對有效。

鋰電池修(xiu)復(fu)方法三的(de)原理

鋰電(dian)池的循(xun)環使用(yong)壽(shou)命(ming)約(yue)600多次。如果充電(dian)(dian)次數多了(le)，分子的(de)(de)熱運動會使其內(nei)部分子排列微觀結(jie)構(gou)逐漸(jian)被破(po)壞，存儲電(dian)(dian)荷(he)效率會漸(jian)漸(jian)降低。而冷凍的(de)(de)過程容易破(po)壞電(dian)(dian)池(chi)(chi)原來的(de)(de)內(nei)部結(jie)構(gou)，短時間內(nei)或許(xu)可以增加充載電(dian)(dian)荷(he)的(de)(de)能(neng)力，但長期(qi)使用(yong)未必有(you)效。鋰電(dian)(dian)池(chi)(chi)內(nei)的(de)(de)微觀結(jie)構(gou)一旦被破(po)壞，再要完全恢復過來是不可能(neng)的(de)(de)，長期(qi)使用(yong)這種方法會加速(su)手機電(dian)(dian)池(chi)(chi)的(de)(de)損耗。

鋰電池修復方法三的原理：對手機進行深度放電，就是通過耗盡內部電能，來達到更深程度的再充電，這需要采用一些非常規的方法。想辦法將手機與一個1.5V小燈泡相(xiang)連(lian)，鋰電(dian)池內部(bu)的(de)電(dian)量會傳輸到小燈泡上，直到全(quan)部(bu)都放光。手機需要通(tong)過較(jiao)低(di)的(de)電(dian)壓慢(man)慢(man)耗盡(jin)電(dian)能。正常(chang)情況下(xia)，手機接(jie)通(tong)后若低(di)于3.6伏的(de)額定電(dian)(dian)(dian)壓，就(jiu)會自(zi)動關(guan)機(ji)。放完(wan)電(dian)(dian)(dian)后，再(zai)次(ci)充電(dian)(dian)(dian)的(de)手機(ji)電(dian)(dian)(dian)池(chi)可(ke)以使(shi)用(yong)更長時間(jian)。
