高倍率電(dian)池(chi)一般指(zhi)的是(shi)鋰電(dian)池(chi)，鋰離子電(dian)池(chi)是(shi)一種充電(dian)高倍率電(dian)池(chi)，它主要依(yi)賴鋰離子在正極和(he)負極之間移(yi)動來(lai)工作。

高倍率電池

在(zai)充(chong)放(fang)電(dian)(dian)(dian)過(guo)程(cheng)中，li+在(zai)兩個電(dian)(dian)(dian)極(ji)(ji)之間來回嵌(qian)(qian)入和(he)脫嵌(qian)(qian)：充(chong)電(dian)(dian)(dian)池(chi)時(shi)，li+從正(zheng)極(ji)(ji)脫嵌(qian)(qian)，經由(you)電(dian)(dian)(dian)解質嵌(qian)(qian)入負(fu)極(ji)(ji)，負(fu)極(ji)(ji)處于(yu)富鋰(li)狀態;放(fang)電(dian)(dian)(dian)時(shi)則(ze)相(xiang)反(fan)。一(yi)般(ban)采用含有鋰(li)元素的材料作(zuo)為電(dian)(dian)(dian)極(ji)(ji)的電(dian)(dian)(dian)池(chi)。是(shi)現代(dai)(dai)高機能電(dian)(dian)(dian)池(chi)的代(dai)(dai)表。

鋰電(dian)(dian)池(chi)(chi)分(fen)為高(gao)倍(bei)(bei)率(lv)電(dian)(dian)池(chi)(chi)和鋰離子(zi)電(dian)(dian)池(chi)(chi)。目(mu)前手機和筆記本(ben)電(dian)(dian)腦使用的都(dou)是鋰離子(zi)電(dian)(dian)池(chi)(chi)，通(tong)常(chang)人們俗(su)稱其為高(gao)倍(bei)(bei)率(lv)電(dian)(dian)池(chi)(chi)，而真正的高(gao)倍(bei)(bei)率(lv)電(dian)(dian)池(chi)(chi)因為危險性大，很少應用于日(ri)常(chang)電(dian)(dian)子(zi)產品。

鋰(li)離子(zi)電池(chi)能量密度(du)大(da)，均(jun)勻輸出電壓高。自放電小，好(hao)的電池(chi)，每月在2%以(yi)下(可恢復)。沒(mei)有(you)(you)(you)記(ji)憶(yi)效(xiao)應。工作溫度(du)范圍寬為(wei)-20℃～60℃。輪回(hui)機能優勝、可快(kuai)速充放電、充電效(xiao)率高達100%，而且輸出功率大(da)。使用壽(shou)命長。不含有(you)(you)(you)毒有(you)(you)(you)害物質，被稱(cheng)為(wei)綠(lv)色(se)電池(chi)。

充電

充電(dian)(dian)是電(dian)(dian)池(chi)(chi)(chi)(chi)重復使用的(de)(de)重要步(bu)驟，鋰離子(zi)電(dian)(dian)池(chi)(chi)(chi)(chi)的(de)(de)充電(dian)(dian)過程分為(wei)兩個階段(duan)：恒(heng)(heng)流(liu)快充階段(duan)和恒(heng)(heng)壓(ya)電(dian)(dian)流(liu)遞減階段(duan)。恒(heng)(heng)流(liu)快充階段(duan)，電(dian)(dian)池(chi)(chi)(chi)(chi)電(dian)(dian)壓(ya)逐(zhu)步(bu)升(sheng)高到電(dian)(dian)池(chi)(chi)(chi)(chi)的(de)(de)尺度電(dian)(dian)壓(ya)，隨后在控制芯片(pian)下轉入恒(heng)(heng)壓(ya)階段(duan)，電(dian)(dian)壓(ya)不(bu)再升(sheng)高以(yi)確保不(bu)會(hui)過充，電(dian)(dian)流(liu)則跟(gen)著電(dian)(dian)池(chi)(chi)(chi)(chi)電(dian)(dian)量的(de)(de)上升(sheng)逐(zhu)步(bu)減弱到設定(ding)的(de)(de)值，而終極完成充電(dian)(dian)。

電(dian)(dian)量(liang)統計(ji)芯片通過記實放(fang)電(dian)(dian)曲線可以抽樣計(ji)算出電(dian)(dian)池(chi)的(de)電(dian)(dian)量(liang)。鋰離(li)子(zi)電(dian)(dian)池(chi)在(zai)(zai)多次(ci)使(shi)用后(hou)，放(fang)電(dian)(dian)曲線會發生改(gai)變，鋰離(li)子(zi)電(dian)(dian)池(chi)固(gu)然不存(cun)在(zai)(zai)記憶效應，但(dan)是(shi)充、放(fang)電(dian)(dian)不當會嚴峻影響(xiang)電(dian)(dian)池(chi)機(ji)能。

充電注意事項

鋰(li)離子(zi)電(dian)池過度充放電(dian)會對正負(fu)極造成永久性損(sun)壞。過度放電(dian)導致負(fu)極碳片層結構泛起塌(ta)陷(xian)，而塌(ta)陷(xian)會造成充電(dian)過程中(zhong)鋰(li)離子(zi)無法(fa)插入;過度充電(dian)使過多的鋰(li)離子(zi)嵌入負(fu)極碳結構，而造成其(qi)中(zhong)部門鋰(li)離子(zi)再(zai)也無法(fa)開釋出來。

充電(dian)(dian)量即(ji)是充電(dian)(dian)電(dian)(dian)流(liu)乘以充電(dian)(dian)時間(jian)，在充電(dian)(dian)控制電(dian)(dian)壓一定的(de)情(qing)況下，充電(dian)(dian)電(dian)(dian)流(liu)越(yue)(yue)大(充電(dian)(dian)速度越(yue)(yue)快)，充電(dian)(dian)電(dian)(dian)量越(yue)(yue)小。

電(dian)(dian)池充電(dian)(dian)速(su)渡過快和終(zhong)止電(dian)(dian)壓控制點不當，同樣會造(zao)成電(dian)(dian)池容量不足，實際是電(dian)(dian)池的部門(men)電(dian)(dian)極活性物質沒有得到充分反(fan)應(ying)就(jiu)休(xiu)止充電(dian)(dian)，這種充電(dian)(dian)不足的現象跟著輪(lun)回次(ci)數的增加而加劇。

放電

第一次充放(fang)電(dian)(dian)(dian)，假如時(shi)(shi)(shi)間能較長(一般3--4小時(shi)(shi)(shi)足(zu)夠(gou))，那么可以(yi)(yi)使電(dian)(dian)(dian)極盡可能多的達到(dao)(dao)最高氧(yang)化(hua)態(充足(zu)電(dian)(dian)(dian))，放(fang)電(dian)(dian)(dian)(或使用)時(shi)(shi)(shi)則強制放(fang)到(dao)(dao)劃定(ding)的電(dian)(dian)(dian)壓(ya)、或直至自動關(guan)機，如斯能激活(huo)電(dian)(dian)(dian)池使用容量。但在鋰離(li)子電(dian)(dian)(dian)池的尋常使用中，不需(xu)要這樣操縱，可以(yi)(yi)隨時(shi)(shi)(shi)根據需(xu)要充電(dian)(dian)(dian)，充電(dian)(dian)(dian)時(shi)(shi)(shi)既不必要一定(ding)布滿電(dian)(dian)(dian)為(wei)止，也不需(xu)要先放(fang)電(dian)(dian)(dian)。像首(shou)次充放(fang)電(dian)(dian)(dian)那樣的操縱，只(zhi)需(xu)要每(mei)隔3--4個月進行連續的1--2次即可。

高倍率電池的應用

對于(yu)(yu)電動(dong)(dong)汽車(che)(che)和混合動(dong)(dong)力車(che)(che)來說，其核(he)心技術在于(yu)(yu)高(gao)倍率電池，與其他類型的(de)(de)電池比較，動(dong)(dong)力鋰離(li)子電池雖(sui)然具有價格高(gao)、安全性能差的(de)(de)缺點(dian)，但(dan)其具有比能量大、循環壽命長等重要優(you)點(dian)，因(yin)此具有更廣(guang)闊的(de)(de)發展(zhan)前景。

動力鋰離子電(dian)池的(de)技術發展(zhan)也(ye)日新月異，從容量及結構上都有所改進，有關專家表(biao)示，無論電(dian)池廠商(shang)采用哪種技術路線，都應滿足(zu)使用安全性(xing)高(gao)(gao)、環(huan)境(jing)溫差范圍廣、充放電(dian)功(gong)能性(xing)強、高(gao)(gao)倍(bei)率放電(dian)使用性(xing)好等條件。

電池(chi)(chi)容量大小(xiao)(xiao)涉(she)及技術(shu)和(he)成(cheng)本鋰離(li)子(zi)(zi)電池(chi)(chi)按體(ti)積大小(xiao)(xiao)可(ke)分為小(xiao)(xiao)電池(chi)(chi)和(he)大電池(chi)(chi)兩(liang)種，小(xiao)(xiao)電池(chi)(chi)通常應用于3C電子(zi)(zi)產品(pin)，相關技術(shu)及產業已經(jing)發展得十分成(cheng)熟(shu)，總(zong)體(ti)利(li)潤(run)呈降低趨勢。目前的鋰離(li)子(zi)(zi)電池(chi)(chi)產品(pin)，85%以上是(shi)小(xiao)(xiao)電池(chi)(chi)。

大(da)電(dian)(dian)(dian)(dian)池(chi)(chi)又(you)俗稱動(dong)(dong)力(li)(li)電(dian)(dian)(dian)(dian)池(chi)(chi)，同(tong)樣有(you)小型動(dong)(dong)力(li)(li)電(dian)(dian)(dian)(dian)池(chi)(chi)和(he)(he)大(da)型動(dong)(dong)力(li)(li)電(dian)(dian)(dian)(dian)池(chi)(chi)兩種，前者主(zhu)要用(yong)于電(dian)(dian)(dian)(dian)動(dong)(dong)工具、電(dian)(dian)(dian)(dian)動(dong)(dong)自(zi)行車(che)(che)等(deng)，后者用(yong)于電(dian)(dian)(dian)(dian)動(dong)(dong)汽車(che)(che)和(he)(he)儲能領域，都使用(yong)高(gao)倍率電(dian)(dian)(dian)(dian)池(chi)(chi)。目前，純(chun)電(dian)(dian)(dian)(dian)動(dong)(dong)(EV)、可插電(dian)(dian)(dian)(dian)式(shi)混合動(dong)(dong)力(li)(li)(PHEV)、混合動(dong)(dong)力(li)(li)(HEV)3種類型的(de)動(dong)(dong)力(li)(li)汽車(che)(che)正處在快速發展(zhan)時期(qi)，備受行業(ye)關注(zhu)(zhu)。作為未(wei)來汽車(che)(che)產(chan)業(ye)的(de)核心，動(dong)(dong)力(li)(li)鋰離子電(dian)(dian)(dian)(dian)池(chi)(chi)產(chan)業(ye)的(de)發展(zhan)受到(dao)(dao)了空前關注(zhu)(zhu)，已被各(ge)主(zhu)要國家(jia)上升到(dao)(dao)了戰略(lve)高(gao)度(du)。
