由(you)于(yu)磷酸(suan)铁(tie)(tie)锂电(dian)(dian)池具(ju)有(you)比(bi)能量高、循环寿命长(zhang)、安全性能好等(deng)优点,因(yin)此广(guang)泛应(ying)用于(yu)各种电(dian)(dian)动汽(qi)车,而磷酸(suan)铁(tie)(tie)锂电(dian)(dian)池的(de)平均使用寿命为(wei)3年(nian)左右,这(zhei)意味(wei)着每(mei)年(nian)都有(you)大(da)量的(de)废(fei)旧(jiu)磷酸(suan)铁(tie)(tie)锂电(dian)(dian)池。
将废(fei)电池拆(chai)解后可得到金属外壳(qiao)、铝(lv)箔、铜箔和塑料隔膜。金属外壳(qiao)和塑料膜片被均(jun)匀回收(shou)和专(zhuan)业加工,铝(lv)箔和铜箔被不同方式回收(shou)利用。
同时,在对废旧磷(lin)酸铁锂(li)电池(chi)电极进行(xing)处理之(zhi)前,应(ying)(ying)根据其内部组成特点进行(xing)相应(ying)(ying)的预处理,主要包括放电电池(chi)剩余电量、拆除电池(chi)、粉碎金(jin)属外壳(qiao)等(deng)。
在放(fang)电(dian)(dian)(dian)处(chu)理中,不同(tong)种类的(de)(de)电(dian)(dian)(dian)池(chi)采(cai)用不同(tong)的(de)(de)处(chu)理方法,功率较小的(de)(de)小型电(dian)(dian)(dian)池(chi)可采(cai)用浸(jin)入电(dian)(dian)(dian)解液(ye)短路的(de)(de)方法使(shi)电(dian)(dian)(dian)池(chi)失活。而对于动力电(dian)(dian)(dian)池(chi)这样大(da)的(de)(de)电(dian)(dian)(dian)池(chi),由(you)于其剩(sheng)余电(dian)(dian)(dian)量可能比较大(da),通常采(cai)用放(fang)电(dian)(dian)(dian)设备放(fang)电(dian)(dian)(dian)处(chu)理,等起(qi)电(dian)(dian)(dian)量耗尽(jin)再拆解电(dian)(dian)(dian)池(chi)。
目前(qian),废旧磷酸铁(tie)锂(li)电(dian)池的回收(shou)研究主要集中在正极上(shang),需要在收(shou)到(dao)磷酸铁(tie)锂(li)粉末前(qian)进(jin)行(xing)前(qian)期处理,一般采用(yong)有机溶剂溶解粘(zhan)结(jie)剂、高温烧结(jie)的方法(fa),将(jiang)电(dian)极上(shang)的铝箔活性物质磷酸铁(tie)锂(li)溶解,然后再(zai)进(jin)行(xing)后续收(shou)集。常用(yong)的回收(shou)技术大致可分为湿法(fa)回收(shou)、火法(fa)回收(shou)和生物浸出回收(shou)。
