钛酸锂电池的优点有哪些?

2022-07-07

锂电池

由于钛酸(suan)锂(li)电(dian)(dian)(dian)(dian)池(chi)(chi)自身(shen)的特点,在(zai)(zai)充放电(dian)(dian)(dian)(dian)循(xun)环(huan)反应(ying)过程中容易(yi)与(yu)电(dian)(dian)(dian)(dian)解(jie)液发生(sheng)相互作用,产(chan)生(sheng)气(qi)体沉淀。因此,普(pu)(pu)通钛酸(suan)锂(li)电(dian)(dian)(dian)(dian)池(chi)(chi)容易(yi)发生(sheng)气(qi)体膨胀(zhang),导(dao)致(zhi)电(dian)(dian)(dian)(dian)池(chi)(chi)鼓(gu)包膨胀(zhang),电(dian)(dian)(dian)(dian)性能(neng)明(ming)显(xian)下降(jiang),电(dian)(dian)(dian)(dian)池(chi)(chi)使用寿命也大大缩短。根据测试数据表明(ming),普(pu)(pu)通钛酸(suan)锂(li)电(dian)(dian)(dian)(dian)池(chi)(chi)在(zai)(zai)循(xun)环(huan)1500 ~ 2000次左右(you)后(hou)会出现膨胀(zhang)现象,膨胀(zhang)后(hou)的电(dian)(dian)(dian)(dian)池(chi)(chi)无法(fa)正常(chang)使用。

钛酸锂电(dian)池(chi)具(ju)有以下优(you)点(dian):

1、具有体积小、重量轻、能量密(mi)度(du)(du)高、密(mi)封(feng)性能好、无(wu)泄漏(lou)、无(wu)记忆效应、自放电率低、充放电快、循环寿命长、工作环境温度(du)(du)范围宽、安全、绿色(se)环保等特点。

2、钛(tai)酸锂作(zuo)为负极材料(liao)的电位平台(tai)高(gao)达1.55V,比(bi)传统石墨(mo)负极材料(liao)高(gao)出1V以上(shang),存在能量密度损失(shi)的情况(kuang),但其安全(quan)性(xing)更高(gao)。

3、可(ke)以在高温、低温环境中(zhong)安全使用。
