早在1886年,霍尔与赫洛尔一起在制铝方法研究中取得了炼铝专利,同时就研究了铝电解添加氟化锂改善电解质的试验,试验是成功的。当时由于锂盐价格昂贵,限制了它在实际中的应用。 1960年以后,锂盐价格大幅度下降,于是吸引许多科学工作者积极从事铝电解添加锂的研究,由理论研究发展到半工业、工业试验;由少量试验槽发展到全系列试验。直到目前为止,对于铝电解添加锂盐方法的评价,由于许多应用碳酸锂的工厂对效果鉴定有不同的标准,以及各地电力及其它费用差别很大,这就很难在使用碳酸锂之后,
As early as 1886, Hall and Hyeror made the patent on aluminum refining in the research of aluminum production method. At the same time, they studied the experiment of aluminum electrolysis adding lithium fluoride to improve the electrolyte. The experiment was successful. Lithium salt was expensive at that time, limiting its practical application. After 1960, the price of lithium salt dropped significantly, so many scientists were attracted to actively engaged in the research of lithium addition to aluminum electrolysis, from theoretical research to semi-industrial and industrial tests; from a small number of test tanks to a full range of tests. Until now, the evaluation of the method for adding lithium salt to aluminum electrolysis has made it difficult for many lithium carbonate-applied factories to have different standards of effect appraisal and large differences in electricity and other costs across the country,
