如何在(zai)满足(zu)空(kong)间(jian)和成本(ben)要求的(de)(de)同(tong)时，在(zai)很短的(de)(de)时间(jian)内提供锂(li)离子充电(dian)(dian)管理解决方案。聚合物锂(li)离子电(dian)(dian)池广泛应用于便携(xie)式消费电(dian)(dian)子产(chan)品中(zhong)。设计一个由聚合物锂(li)离子电(dian)(dian)池供电(dian)(dian)的(de)(de)系(xi)统(tong)的(de)(de)传统(tong)方法是将系(xi)统(tong)负载直接连接到电(dian)(dian)池上。系(xi)统(tong)负载会导致锂(li)离子电(dian)(dian)池持续放(fang)电(dian)(dian)，消耗电(dian)(dian)池的(de)(de)寿命(ming)周(zhou)期

铝空气电(dian)(dian)(dian)池(chi)的(de)(de)特点：1、比(bi)(bi)能(neng)高，电(dian)(dian)(dian)池(chi)的(de)(de)理论比(bi)(bi)能(neng)可(ke)达(da)2290Wh /kg。目前实际已经(jing)达(da)到300~ 400Wh /kg，远高于(yu)各(ge)种电(dian)(dian)(dian)池(chi)的(de)(de)比(bi)(bi)能(neng)。虽然电(dian)(dian)(dian)池(chi)的(de)(de)比(bi)(bi)能(neng)量是相(xiang)似的(de)(de)，但其较差的(de)(de)安全性使其不能(neng)用于(yu)动力电(dian)(dian)(dian)池(chi)。2、比(bi)(bi)功率适中，可(ke)达(da)50~ 200W /kg。这(zhei)

目(mu)前，能够替代(dai)锂(li)电(dian)池(chi)(chi)的铝(lv)(lv)(lv)(lv)电(dian)池(chi)(chi)还处于试生产阶段，尚未(wei)投入商业使(shi)用。所以总的来说，铝(lv)(lv)(lv)(lv)空(kong)气电(dian)池(chi)(chi)是(shi)否会取代(dai)锂(li)电(dian)池(chi)(chi)还是(shi)未(wei)知数，那么了解下(xia)铝(lv)(lv)(lv)(lv)空(kong)气电(dian)池(chi)(chi)在更换锂(li)电(dian)池(chi)(chi)时会遇到哪些问题(ti)。就续航来说，铝(lv)(lv)(lv)(lv)空(kong)气电(dian)池(chi)(chi)确(que)实(shi)是(shi)锂(li)电(dian)池(chi)(chi)的一大突破。但铝(lv)(lv)(lv)(lv)空(kong)气电(dian)池(chi)(chi)在放电(dian)过程中由于阳(yang)极腐蚀，
