目前，能够替代锂(li)电(dian)(dian)(dian)池(chi)(chi)的(de)铝电(dian)(dian)(dian)池(chi)(chi)还(hai)处(chu)于试(shi)生产阶段(duan)，尚未投(tou)入商业使用(yong)。所以总的(de)来说，铝空(kong)气电(dian)(dian)(dian)池(chi)(chi)是(shi)(shi)否(fou)会取代锂(li)电(dian)(dian)(dian)池(chi)(chi)还(hai)是(shi)(shi)未知数，那么了解下铝空(kong)气电(dian)(dian)(dian)池(chi)(chi)在更换锂(li)电(dian)(dian)(dian)池(chi)(chi)时会遇到哪些(xie)问(wen)题。

就续(xu)航来说，铝空气(qi)电(dian)池(chi)(chi)(chi)(chi)确实(shi)是锂电(dian)池(chi)(chi)(chi)(chi)的(de)(de)(de)一大突破。但铝空气(qi)电(dian)池(chi)(chi)(chi)(chi)在(zai)放(fang)电(dian)过程中由于(yu)阳(yang)极(ji)腐(fu)蚀(shi)，会产生氢气(qi)，这(zhei)不仅会导致阳(yang)极(ji)材料的(de)(de)(de)损(sun)失，还会增加电(dian)池(chi)(chi)(chi)(chi)的(de)(de)(de)损(sun)耗。另(ling)外，铝空气(qi)电(dian)池(chi)(chi)(chi)(chi)消(xiao)耗的(de)(de)(de)是铝，当电(dian)池(chi)(chi)(chi)(chi)寿命结束时需要重新安装铝，这(zhei)大大阻碍了铝空气(qi)电(dian)池(chi)(chi)(chi)(chi)的(de)(de)(de)商业化(hua)发展。

铝(lv)(lv)空(kong)(kong)(kong)气(qi)电池(chi)的化学反(fan)应与锌空(kong)(kong)(kong)气(qi)电池(chi)相似。铝(lv)(lv)空(kong)(kong)(kong)气(qi)电池(chi)采用高(gao)纯铝(lv)(lv)(99.99%铝(lv)(lv))为(wei)(wei)负极(ji)，氧(yang)为(wei)(wei)正极(ji)，氢(qing)氧(yang)化钾(jia)(KOH)或氢(qing)氧(yang)化钠(NaOH)水(shui)溶液为(wei)(wei)电解(jie)液。铝(lv)(lv)从空(kong)(kong)(kong)气(qi)中吸取(qu)氧(yang)气(qi)，当电池(chi)放电时发生反(fan)应，将铝(lv)(lv)和氧(yang)气(qi)转化为(wei)(wei)氧(yang)化铝(lv)(lv)。

锂电(dian)(dian)(dian)池是(shi)实(shi)际比(bi)能(neng)量高达(da)300~400Wh/ kg且对环境友(you)好的(de)(de)优良电(dian)(dian)(dian)池，电(dian)(dian)(dian)池结(jie)构和(he)材料可(ke)根据实(shi)际环境和(he)要求进行改(gai)变(bian)，具有(you)很强的(de)(de)适应性；它可(ke)用于陆地和(he)深海，可(ke)作为动力电(dian)(dian)(dian)池，是(shi)一种(zhong)长寿命的(de)(de)高比(bi)能(neng)量信号电(dian)(dian)(dian)池。
