一、電池片回收有什么作用

1、減少對環境的污染壓力

如今，隨著社會經濟的發展，社會環境正面臨嚴峻的考驗。一方面，不可生資源的數量正在減少。另一方面，一些污染現象還在不斷破壞環境的平衡結構。比如說部分人隨意丟棄廢舊的電池片。這種情況下，會對環境的土壤、水源等產生(sheng)嚴重危害(hai)。

2、提高資源的使用效率

廢舊電(dian)池片并不(bu)是(shi)沒有用途(tu)，其實，廢舊電(dian)池片可(ke)以(yi)被(bei)再次利用，從而可(ke)以(yi)提高資源(yuan)的使用效率，尤其是(shi)一些不(bu)可(ke)再利用的資源(yuan)能(neng)(neng)夠得(de)到較(jiao)好的保護，既能(neng)(neng)夠延(yan)長資源(yuan)的使用時限，還能(neng)(neng)降低(di)部分物(wu)資對(dui)環(huan)境造成的污染。

3、節省了一定的生產成本

從電池片回(hui)收公司了解到，他們使用廢(fei)舊電池為原料，生產新(xin)的電池成本得到了大(da)幅度(du)降低(di)，實現了“雙贏”的局(ju)面。

在日常的工(gong)作生(sheng)活中，建議大家要(yao)妥善(shan)處理(li)好廢(fei)舊電池(chi)片，尤其是不能(neng)隨意(yi)處置(zhi)，比如(ru)說丟棄在垃圾堆里，那樣將(jiang)(jiang)會造成很大的危害，盡可能(neng)將(jiang)(jiang)廢(fei)舊電池(chi)片收集(ji)起(qi)來送到電池(chi)片回收公司，在實現(xian)廢(fei)舊電池(chi)片回收的同時，對保護環境起(qi)到了很好的作用(yong)。

三、太陽能電池片怎么進行回收

電池片可以回(hui)收，可以從太陽能電池中回(hui)收純硅(gui)。

太陽能電池主要含有硅（約91.6%重量）。它還包含其他材料，例如底層的鋁，頂層的銀電極，以及頂層的鉛和抗反射涂層。p型和n型硅晶片位于抗反射涂層和鋁層之間。太陽能電池片藍色(se)層(ceng)(ceng)是(shi)抗反(fan)射(she)涂層(ceng)(ceng)（SiNx），白線是(shi)銀(yin)電極。太陽能電池片的底部(bu)為(wei)鋁層(ceng)(ceng)。為(wei)了去除(chu)這些(xie)材(cai)料（鋁、銀(yin)、鉛和(he)抗反(fan)射(she)涂層(ceng)(ceng)），需(xu)使用化學處理(li)方法。

首先，氫氟酸(suan)(suan)(suan)(suan)或氫氟酸(suan)(suan)(suan)(suan)與(yu)其他化學(xue)品的混合物用(yong)(yong)于去(qu)除太陽(yang)能(neng)電池的抗(kang)反射涂層(ceng)、銀(yin)、鉛和pn結。由(you)于氫氟酸(suan)(suan)(suan)(suan)是(shi)劇毒和腐(fu)蝕(shi)性化學(xue)品，因此(ci)在目(mu)前的工作(zuo)中不(bu)再使用(yong)(yong)氫氟酸(suan)(suan)(suan)(suan)。每一(yi)(yi)層(ceng)都使用(yong)(yong)化學(xue)處(chu)理一(yi)(yi)層(ceng)一(yi)(yi)層(ceng)地去(qu)除。

用(yong)濃NaOH溶(rong)液處理后去(qu)除(chu)鋁(lv)層。在(zai)反應過(guo)程中(zhong)(zhong)形(xing)成(cheng)的(de)(de)氫(qing)氣被收集在(zai)一個腔室中(zhong)(zhong)并可(ke)用(yong)作燃料(liao)。通過(guo)過(guo)濾從NaOH溶(rong)液中(zhong)(zhong)分離氫(qing)氧化(hua)鋁(lv)。類似地，通過(guo)用(yong)HNO3處理去(qu)除(chu)銀(yin)和鉛(qian)(qian)(qian)。收集釋放的(de)(de)NO2并可(ke)用(yong)于生產硝(xiao)(xiao)酸。分離硝(xiao)(xiao)酸銀(yin)，溶(rong)液用(yong)HCl處理，形(xing)成(cheng)氯化(hua)銀(yin)。濾出沉淀(dian)(dian)的(de)(de)氯化(hua)銀(yin)。此(ci)外(wai)，將溶(rong)液用(yong)NaOH處理以從溶(rong)液中(zhong)(zhong)分離鉛(qian)(qian)(qian)化(hua)合(he)物（PbO）。氧化(hua)鉛(qian)(qian)(qian)轉化(hua)為氫(qing)氧化(hua)鉛(qian)(qian)(qian)，過(guo)濾沉淀(dian)(dian)的(de)(de)氫(qing)氧化(hua)鉛(qian)(qian)(qian)。
