钛酸锂(li)(li)(li)(li)电池的(de)(de)负极(ji)材料为(wei)钛酸锂(li)(li)(li)(li)，可与锰酸锂(li)(li)(li)(li)、三元材料或磷酸铁(tie)锂(li)(li)(li)(li)等正极(ji)材料组成(cheng)2.4V或1.9V的(de)(de)锂(li)(li)(li)(li)离子(zi)二次电池。此外，它(ta)还可以作为(wei)正极(ji)，与锂(li)(li)(li)(li)金属或锂(li)(li)(li)(li)合金负极(ji)形(xing)成(cheng)1.5V锂(li)(li)(li)(li)二次电池。但在(zai)生活中，我(wo)们很少见到钛酸锂(li)(li)(li)(li)电池，其并没有在(zai)生活中得到广泛的(de)(de)应用，这是(shi)为(wei)什(shen)么呢？
钛酸锂(li)电池有着良好(hao)的(de)安全性，其研(yan)究(jiu)一直(zhi)是厂家的(de)热点，但因(yin)为(wei)Li, Tis0:材料的(de)电子电导率(lv)和(he)(he)锂(li)离子扩散系数(shu)很低，从而限(xian)制(zhi)其在大(da)(da)倍(bei)率(lv)充放(fang)电的(de)应(ying)用。Li和(he)(he)TiO纳米颗粒可以(yi)扩大(da)(da)有效反应(ying)面积，减小扩散距(ju)离，大(da)(da)大(da)(da)提(ti)高材料的(de)速(su)率(lv)性能。但由于(yu)材料颗粒纳米化(hua)(hua)工(gong)艺难度(du)大(da)(da)，成(cheng)本高，目前难以(yi)实现大(da)(da)规模(mo)工(gong)业化(hua)(hua)生产(chan)。
钛酸(suan)锂电池(chi)在(zai)循(xun)环(huan)使用中会不(bu)断(duan)产生气(qi)体，易使电池(chi)膨胀，在(zai)高(gao)温下这种现象尤(you)其严重，影响正(zheng)负(fu)电极接触，增(zeng)加电池(chi)阻抗，影响电池(chi)性能(neng)，这也是(shi)钛酸(suan)锂电池(chi)没有得到广泛应用的主要原因之一。
