摘要

结果表明，在处理复杂化学电源(CCPS)时，必须对其进行预放电，使其安全剩余电压最高为1 V。对国外采用各种方法对锂-钴电池、锂-镍-钴-锰电池和锂-锰电池(LCO、NCM、LMO电池)放电的研究数据进行了分析。介绍了在NaCl 5、10、15 wt.%和na2co310 wt.%溶液中电池放电的实验研究结果。结果表明，盐溶液中的放电是通过电解进行的。实验证实，na2co3的使用导致了碳酸盐的水解。根据雷诺准则(ReM)，图中显示了各种电池的放电对放电时间和搅拌器水动力参数的依赖关系。测定了电池放电过程中形成的沉淀物的组成。提出了关于混合装置的制度参数和安全排放程序的建议。

Development of a Safe Technology for the Processing of lithium-ion Batteries, Including the Stages of Discharging in Saline Ssolutions and Granulation of Target Products

It was shown that when disposing of complex chemical power sources (CCPS), they must be subjected to a preliminary discharge to a safe residual voltage of 1 V maximum. The data of foreign studies on the discharge of Lithium-Cobalt, Lithium-Nickel-Cobalt-Manganese and Lithium-Manganese batteries (LCO, NCM, LMO batteries, respectively) by various methods were analyzed. The results of experimental studies of battery discharges in NaCl 5, 10, 15 wt.% and Na 2 CO 3 10 wt.% solutions were presented. It was found that the discharge in saline solutions proceeds by electrolysis. It was confirmed that the use of Na 2 CO 3 leads to the hydrolysis of carbonates. The graphs show the dependences of the discharge of various batteries on the discharge time and the hydrodynamic parameters of the agitator according to the Reynolds criterion (ReM). The composition of precipitation formed during the discharge of the battery was determined. Recommendations were developed on the regime parameters of mixing devices and the safe discharge procedure.

期刊介绍： The Journal "Ekologia i promyshlennost Rossii" («Ecology and Industry of Russia») is aimed to promote acquaintance of the world scientific and technical public and specialists, interested in the problems of the environment protection, with advanced achievements of the science and engineering practice on securing of stable (self-supporting) evolution within the limits of the United Nations accepted recommendations (RIO 92 and RIO+20). A circle of papers includes basic researches and engineering decisions, analytical and methodical operations, reviews on journal subjects. The journal lays special emphasis on methodical elaborations, analytical investigations in the sphere of creating the ecological culture of the population, to the features of ecological education in higher schools of the country for the sake of actualization in specialists'' consciousness of the scientific necessity to know environmental problems of the modern civilization and paths of their settlement. Original papers and investigations of scientists and specialists on separate themes occupy an independent niche of issues under the «Cover story» heading. The journal task is to promote practical implementation of scientific and engineering decisions in the field of decrease of anthropogenic load on the biosphere and environment protection (open lectures, round tables, discussions and so forth). Ecology and Industry of Russia is an informational reference book about the newest developments of the Russian and foreign scientists and the companies realized in Russia, the CIS and Baltic countries, and far-abroad countries. The journal publishes information reports about holding in Russia and abroad the international, all-Russian and regional congresses, conferences, and symposiums related to the journal subjects.
