4.35V高壓鋰電芯介紹

高(gao)壓(ya)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)是(shi)指電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)電(dian)(dian)(dian)(dian)壓(ya)比較相對于(yu)普通電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)來說(shuo)比較高(gao)的(de)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)。單片(pian)鋰(li)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)標稱電(dian)(dian)(dian)(dian)壓(ya)一般(ban)來說(shuo)都是(shi)在3.7V左右(you)，然后(hou)滿電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓(ya)就為(wei)4.2V。滿電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓(ya)超(chao)過4.2V的(de)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)即(ji)可(ke)定義為(wei)高(gao)壓(ya)鋰(li)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)。像大家不經常看(kan)到(dao)的(de)4.35V高(gao)壓(ya)鋰(li)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)就是(shi)這(zhe)么一種。那(nei)么4.35V高(gao)壓(ya)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)有(you)什么好處呢？

這就要考慮電(dian)(dian)池的放(fang)電(dian)(dian)功(gong)耗(hao)是 P = V*I (實(shi)際(ji)隨著(zhu)放(fang)電(dian)(dian)電(dian)(dian)壓下降(jiang)，電(dian)(dian)池的總能量(liang)(liang)應該是是每個(ge)單位時(shi)間(jian)實(shi)際(ji)電(dian)(dian)壓和電(dian)(dian)流(liu)乘積的積分）這里很(hen)明顯就看到(dao)，提(ti)高(gao)(gao)最高(gao)(gao)截止電(dian)(dian)壓可(ke)(ke)以增加電(dian)(dian)池的總放(fang)電(dian)(dian)能量(liang)(liang)。在實(shi)際(ji)應用(yong)中，只有部分鋰離子(zi)可(ke)(ke)以被可(ke)(ke)逆地嵌入和噴出，實(shi)際(ji)能量(liang)(liang)密(mi)度約(yue)為(wei)167mAh/g（工作(zuo)(zuo)電(dian)(dian)壓為(wei)4.35v）。提(ti)高(gao)(gao)工作(zuo)(zuo)電(dian)(dian)壓可(ke)(ke)以顯著(zhu)提(ti)高(gao)(gao)能量(liang)(liang)密(mi)度。例如，將工作(zuo)(zuo)電(dian)(dian)壓從4.2v提(ti)高(gao)(gao)到(dao)4.35v，可(ke)(ke)以使(shi)能量(liang)(liang)密(mi)度提(ti)高(gao)(gao)16%左右。

高(gao)壓鋰(li)(li)電(dian)(dian)池(chi)要比(bi)(bi)普通(tong)鋰(li)(li)電(dian)(dian)池(chi)放電(dian)(dian)倍率更(geng)高(gao)，動力更(geng)強，因此高(gao)壓電(dian)(dian)池(chi)電(dian)(dian)芯理論(lun)上(shang)來(lai)說應該比(bi)(bi)較(jiao)適合應用在需要高(gao)倍率放電(dian)(dian)的產(chan)品設備上(shang)，才能更(geng)好的發揮其優勢。比(bi)(bi)如(ru)說我們常看到的無人(ren)機、車(che)模、航模等。國家高(gao)新技術企(qi)業格瑞普的4.35V高(gao)壓鋰(li)(li)電(dian)(dian)芯就廣泛(fan)的適用于這些產(chan)品。

高(gao)(gao)壓電(dian)池意味著高(gao)(gao)能量(liang)密度，高(gao)(gao)放電(dian)平(ping)臺，相同的使用條件下，高(gao)(gao)壓電(dian)池能放出更多的容量(liang)。所以其(qi)續航時(shi)間(jian)更長(chang)，動力也(ye)更強。 正常(chang)情況(kuang)下，格(ge)瑞(rui)普的高(gao)(gao)壓電(dian)池的續航時(shi)間(jian)會提升15%-25%，這個也(ye)是格(ge)瑞(rui)普電(dian)池的其(qi)中一個核心技術,它具有如下優(you)點(dian)。

1、高(gao)能量密度(du)，續(xu)航時間更長，比(bi)普通(tong)電池高(gao)達(da)15%；

2、放電(dian)平(ping)臺高且穩定，頻繁使用(yong)并不影(ying)響電(dian)池的壽命；

3、相同倍率、尺寸情(qing)況下(xia)，電池能量密度提升15%左右；

4、倍(bei)率循環性能可滿(man)足(zu)300次(ci)之(zhi)后保持原有80%的容量(liang)；

5、模擬實際使(shi)用進行(xing)可靠性實驗測，可滿足3年使(shi)用壽命，滿足高低(di)溫、不同倍率需求動力行(xing)業應用；

6、具備大(da)規(gui)模量產的能力，電(dian)芯一致性好(hao)。
