膨胀的手机电池

今(jin)天(tian)，我(wo)(wo)(wo)的(de)(de)手(shou)(shou)(shou)(shou)机(ji)(ji)(ji)(ji)正放(fang)在桌上(shang)(shang)充(chong)电(dian)(dian)(dian)，我(wo)(wo)(wo)拿起(qi)手(shou)(shou)(shou)(shou)机(ji)(ji)(ji)(ji)，打开游戏，玩了(le)(le)起(qi)来。手(shou)(shou)(shou)(shou)机(ji)(ji)(ji)(ji)的(de)(de)电(dian)(dian)(dian)已(yi)经充(chong)满了(le)(le)，忽(hu)然(ran)，手(shou)(shou)(shou)(shou)机(ji)(ji)(ji)(ji)的(de)(de)后盖“砰”地一(yi)声弹了(le)(le)出(chu)来，电(dian)(dian)(dian)池(chi)也(ye)紧跟(gen)其后，我(wo)(wo)(wo)急忙(mang)放(fang)下(xia)手(shou)(shou)(shou)(shou)机(ji)(ji)(ji)(ji)，扯(che)下(xia)电(dian)(dian)(dian)源，捡(jian)起(qi)地上(shang)(shang)的(de)(de)手(shou)(shou)(shou)(shou)机(ji)(ji)(ji)(ji)盖和电(dian)(dian)(dian)池(chi)，电(dian)(dian)(dian)池(chi)已(yi)经膨胀了(le)(le)，我(wo)(wo)(wo)坐到(dao)(dao)椅子(zi)上(shang)(shang)，试着(zhe)把电(dian)(dian)(dian)池(chi)装(zhuang)到(dao)(dao)手(shou)(shou)(shou)(shou)机(ji)(ji)(ji)(ji)上(shang)(shang)，可它(ta)们像是(shi)有深仇大恨一(yi)般，电(dian)(dian)(dian)池(chi)无论如何也(ye)装(zhuang)不上(shang)(shang)去，有时装(zhuang)上(shang)(shang)了(le)(le)，可电(dian)(dian)(dian)池(chi)像是(shi)排(pai)斥它(ta)一(yi)样，又会(hui)闪电(dian)(dian)(dian)般弹出(chu)来，落在手(shou)(shou)(shou)(shou)机(ji)(ji)(ji)(ji)盖里，他和手(shou)(shou)(shou)(shou)机(ji)(ji)(ji)(ji)盖好像是(shi)一(yi)对亲兄弟。看(kan)到(dao)(dao)这个，我(wo)(wo)(wo)急忙(mang)去找爸(ba)(ba)爸(ba)(ba)，爸(ba)(ba)爸(ba)(ba)说：“你(ni)不能再用这个手(shou)(shou)(shou)(shou)机(ji)(ji)(ji)(ji)了(le)(le)，会(hui)有危(wei)险。”我(wo)(wo)(wo)说：“怎么(me)会(hui)呢？”爸(ba)(ba)爸(ba)(ba)说：“你(ni)明天(tian)上(shang)(shang)网查查吧！”

第二(er)天，我打(da)开电(dian)(dian)(dian)(dian)(dian)脑(nao)查(cha)手(shou)(shou)机电(dian)(dian)(dian)(dian)(dian)池(chi)(chi)为(wei)什么会膨(peng)胀。哦，原来手(shou)(shou)机在(zai)待(dai)机时(shi)(shi)的(de)功耗(hao)(hao)是(shi)很(hen)小(xiao)(xiao)的(de)，也(ye)(ye)就是(shi)说它(ta)的(de)电(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)等效(xiao)负(fu)荷电(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)大，所以(yi)放(fang)电(dian)(dian)(dian)(dian)(dian)电(dian)(dian)(dian)(dian)(dian)流很(hen)小(xiao)(xiao)所以(yi)电(dian)(dian)(dian)(dian)(dian)池(chi)(chi)不(bu)会发(fa)热，电(dian)(dian)(dian)(dian)(dian)池(chi)(chi)电(dian)(dian)(dian)(dian)(dian)能(neng)(neng)的(de)内耗(hao)(hao)很(hen)小(xiao)(xiao)。而(er)手(shou)(shou)机在(zai)待(dai)通话或(huo)游戏(xi)时(shi)(shi)的(de)功耗(hao)(hao)是(shi)很(hen)大的(de)，也(ye)(ye)就是(shi)说它(ta)的(de)电(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)等效(xiao)负(fu)荷电(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)小(xiao)(xiao)，工(gong)(gong)作时(shi)(shi)是(shi)大电(dian)(dian)(dian)(dian)(dian)流放(fang)电(dian)(dian)(dian)(dian)(dian)。电(dian)(dian)(dian)(dian)(dian)池(chi)(chi)在(zai)放(fang)掉(diao)一(yi)部(bu)分电(dian)(dian)(dian)(dian)(dian)以(yi)后，内阻(zu)(zu)增大，但是(shi)，手(shou)(shou)机的(de)工(gong)(gong)作需要(yao)的(de)电(dian)(dian)(dian)(dian)(dian)流不(bu)能(neng)(neng)减小(xiao)(xiao)，那么，相当大的(de)一(yi)部(bu)分能(neng)(neng)量就消耗(hao)(hao)在(zai)电(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)内阻(zu)(zu)上，导致电(dian)(dian)(dian)(dian)(dian)池(chi)(chi)发(fa)热，放(fang)电(dian)(dian)(dian)(dian)(dian)加速，电(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)使用时(shi)(shi)间也(ye)(ye)就很(hen)快的(de)缩短。

手(shou)机(ji)(ji)(ji)电(dian)池(chi)(chi)发(fa)热的危(wei)害很大，如：1、手(shou)机(ji)(ji)(ji)电(dian)池(chi)(chi)长(zhang)时间(jian)发(fa)热会导(dao)致手(shou)机(ji)(ji)(ji)内部机(ji)(ji)(ji)件(jian)发(fa)热，从而(er)使(shi)手(shou)机(ji)(ji)(ji)重(zhong)新启动或挂(gua)断通话中的电(dian)话。2、手(shou)机(ji)(ji)(ji)电(dian)池(chi)(chi)长(zhang)时间(jian)发(fa)热会使(shi)电(dian)池(chi)(chi)本(ben)身的热量(liang)增(zeng)加(jia)，如果是(shi)密(mi)封的，池(chi)(chi)会使(shi)其内部空气剧烈(lie)膨胀，导(dao)致电(dian)池(chi)(chi)向外突起，严重(zhong)的会使(shi)电(dian)池(chi)(chi)爆(bao)炸。3手(shou)机(ji)(ji)(ji)电(dian)池(chi)(chi)长(zhang)时间(jian)发(fa)热会加(jia)速手(shou)机(ji)(ji)(ji)本(ben)身的老化进程，缩短其寿命。

手(shou)(shou)机电池(chi)(chi)发热的预防方法也有很多(duo)：1手(shou)(shou)机在(zai)正常(chang)室温(wen)时(shi),发热不超过60℃属正常(chang)现象,是(shi)不会损坏(huai)电池(chi)(chi)的。2使用(yong)大(da)电流(liu)充(chong)(chong)电器(qi)时(shi)间(jian)不宜太长(zhang),太长(zhang)时(shi)间(jian)充(chong)(chong)电会使电池(chi)(chi)被损坏(huai)，同时(shi)也会产(chan)生热量。3充(chong)(chong)电器(qi)最(zui)好(hao)使用(yong)原装或质量信誉较好(hao)的产(chan)品。5使用(yong)手(shou)(shou)机听(ting)MP3或电池(chi)(chi)充(chong)(chong)电时(shi)如(ru)感觉手(shou)(shou)机有点热的话(hua)，可(ke)以查看温(wen)度，如(ru)超过60℃的话(hua)立即回到(dao)待机状态或换块(kuai)电池(chi)(chi)使用(yong)，如(ru)在(zai)充(chong)(chong)电的话(hua)就(jiu)立即拔下充(chong)(chong)电器(qi)。

我查(cha)完后(hou)，和婆(po)婆(po)一起去逛街，有位(wei)年轻的穿着(zhe)一件旧长袍的算命先生(sheng)看了(le)一眼我的手机(ji)，小声的对我说(shuo)：“小朋友，你的电池烂了(le)，你有血光之灾(zai)。”我心(xin)想：谁信(xin)你，你们(men)都是邪教的人(ren)，世界上根(gen)本没(mei)有人(ren)可以算命。我一边想着(zhe)，一边跟着(zhe)婆(po)婆(po)走远了(le)。那位(wei)算命先生(sheng)的脸上露出了(le)不满的神情。

原来，膨(peng)胀的手机电池有(you)这么(me)多(duo)危(wei)害，我得小(xiao)心使用(yong)手机了，不(bu)能(neng)发(fa)生这类事(shi)故(gu)，发(fa)生了事(shi)故(gu)，还会伤害别人(ren)。我们(men)应该相(xiang)信科学，不(bu)能(neng)被邪教的人(ren)迷(mi)花了眼(yan)睛(jing)。去相(xiang)信所谓的血光之灾。
