style="text-indent:25px">制備電池級(jí)碳酸鋰的方法：沉淀法 1、：均相沉淀法工業(yè)級(jí)碳酸鋰與石灰乳反響制得LiOH溶液，向溶液中參加高純度的CO(NH2)2，然后一次沉淀出大粒的Li2CO3晶體。所涉及化學(xué)反響如下：均相沉淀法運(yùn)用CO(NH2)2作為均相沉淀劑，能夠避免結(jié)晶分出過快的局部反響，且不易產(chǎn)生二次**，生成的Li2CO3顆粒大，顆粒內(nèi)部不含溶液系統(tǒng)的雜質(zhì)離子。此反響是在氨系統(tǒng)中進(jìn)行，易引進(jìn)新的雜質(zhì)，且Li2CO3的殘留問題嚴(yán)峻，回收率較低。 2、：LiOH沉淀法將工業(yè)級(jí)碳酸鋰與氫氧化鈣反響制得的LiOH，與高純度NH4HCO3反響可得到高純度Li2CO3，該辦法引進(jìn)雜質(zhì)離子較少，產(chǎn)品中殘留的氨可經(jīng)過烘干除掉。將CO2通入LiOH溶液，沉淀制備高純的Li2CO3產(chǎn)品。此辦法Li2CO3產(chǎn)品的純度主要取決于LiOH的純度，操作過程幾乎不引進(jìn)雜質(zhì)離子。這種辦法也是比較直接普遍的制備高純碳酸鋰的辦法。</p><p style="text-indent:25px">隨著新能源汽車的發(fā)展，鋰電池行業(yè)高速發(fā)展，同時(shí)對(duì)碳酸鋰的需求量日益增長(zhǎng)，應(yīng)用范圍不斷擴(kuò)大，對(duì)碳酸鋰的純度越來越高。工業(yè)級(jí)碳酸鋰提純生產(chǎn)電池級(jí)或者高純碳酸鋰勢(shì)在必行。工業(yè)碳酸鋰提純一般采用碳化分解法。該方法操作簡(jiǎn)單、提純效率高、生產(chǎn)成本低、污染小等特點(diǎn)，而且熱分解后的母液部分可返回調(diào)漿循環(huán)利用，有效提高了鋰的回收率。工藝簡(jiǎn)介：工業(yè)級(jí)碳酸鋰和水（或返回母液）按一定比例進(jìn)行調(diào)漿，并加入一定量的絡(luò)合劑得到碳酸鋰料漿。碳酸鋰料漿再經(jīng)過碳化塔在一定壓力和溫度下與二氧化碳進(jìn)行碳化反應(yīng)得到碳酸氫鋰溶液。碳酸氫鋰溶液再經(jīng)過過濾除雜得到凈化液，凈化液再通過分解塔加熱分解得到凈化的碳酸鋰料漿，熱解后的碳酸鋰料漿通過增稠器增稠，再經(jīng)過離心分離、干燥、篩分、除鐵、粉碎、混合、包裝得到電池級(jí)（高純）碳酸鋰。分解的二氧化碳可經(jīng)過二氧化碳回收系統(tǒng)進(jìn)行回收利用。碳酸鋰合成方法：硫酸法將熔融的鋰輝石與硫酸反應(yīng)，經(jīng)凈化后再與碳酸鈉反應(yīng)制得。</p><div
