锂离子电池介绍:
锂(li)离(li)子(zi)(zi)(zi)电(dian)(dian)(dian)池是(shi)可(ke)充电(dian)(dian)(dian)电(dian)(dian)(dian)池的(de)(de)(de)一种,主要依(yi)靠(kao)锂(li)离(li)子(zi)(zi)(zi)在(zai)正极(ji)和(he)负(fu)极(ji)之间移动来工作。传(chuan)统上,锂(li)离(li)子(zi)(zi)(zi)进入(ru)(ru)(ru)(ru)(ru)阴(yin)极(ji)材(cai)料(liao)的(de)(de)(de)过程称(cheng)为(wei)嵌(qian)(qian)入(ru)(ru)(ru)(ru)(ru),离(li)开(kai)(kai)的(de)(de)(de)过程称(cheng)为(wei)脱(tuo)(tuo)嵌(qian)(qian)。锂(li)离(li)子(zi)(zi)(zi)进入(ru)(ru)(ru)(ru)(ru)负(fu)极(ji)材(cai)料(liao)的(de)(de)(de)过程称(cheng)为(wei)插入(ru)(ru)(ru)(ru)(ru),离(li)开(kai)(kai)的(de)(de)(de)过程称(cheng)为(wei)脱(tuo)(tuo)插。像所有化学电(dian)(dian)(dian)池一样(yang),锂(li)离(li)子(zi)(zi)(zi)电(dian)(dian)(dian)池由3部分组成: 正极(ji),负(fu)极(ji)和(he)电(dian)(dian)(dian)解质。电(dian)(dian)(dian)极(ji)材(cai)料(liao)都是(shi)可(ke)以嵌(qian)(qian)入(ru)(ru)(ru)(ru)(ru) (插入(ru)(ru)(ru)(ru)(ru))/脱(tuo)(tuo)嵌(qian)(qian) (脱(tuo)(tuo)插) 的(de)(de)(de)锂(li)离(li)子(zi)(zi)(zi)。锂(li)离(li)子(zi)(zi)(zi)电(dian)(dian)(dian)池的(de)(de)(de)电(dian)(dian)(dian)压为(wei)3.6 ~ 3.7V。
锂(li)离(li)子聚合物(wu)电池的介绍:
锂离子聚合(he)(he)物(wu)电(dian)(dian)(dian)池(chi),又称聚合(he)(he)物(wu)锂电(dian)(dian)(dian)池(chi)、锂聚合(he)(he)物(wu)电(dian)(dian)(dian)池(chi)。它是(shi)以胶(jiao)体聚合(he)(he)物(wu)为电(dian)(dian)(dian)解质(zhi)的可(ke)充电(dian)(dian)(dian)电(dian)(dian)(dian)池(chi)。避(bi)免了锂离子电(dian)(dian)(dian)池(chi)在高温(wen)下容易爆炸的安全问题。与锂离子电(dian)(dian)(dian)池(chi)相比(bi),锂聚合(he)(he)物(wu)电(dian)(dian)(dian)池(chi)的特点如下:
1、不(bu)存(cun)在(zai)电(dian)池漏电(dian)问题。电(dian)池不(bu)含液体电(dian)解质,使用胶(jiao)体固体。
2、它可以(yi)制(zhi)成(cheng)薄电池:它的(de)厚度可以(yi)像0.5毫米一样薄。
3、电池可(ke)以设计成多种形(xing)状,大弯(wan)曲度(du)约为90 °。
4、可(ke)制成单个高压:液体电(dian)(dian)解(jie)质(zhi)的(de)电(dian)(dian)池只(zhi)能与几个电(dian)(dian)池串联才(cai)能获得高压,而聚合(he)物电(dian)(dian)池可(ke)以在(zai)单个电(dian)(dian)池中(zhong)制成多(duo)层组合(he),实现高压,因为它没有液体。
5、容量将是相同尺(chi)寸的(de)锂(li)(li)离子(zi)(zi)电池的(de)两倍(bei)。锂(li)(li)离子(zi)(zi)聚合(he)物电池的(de)电压为3.6 ~ 3.7V。
