Sodium persulfate used by Zhanhua Chemical to promote the recovery of Battery recycling for power of new energy vehicles

Release Time:

In recent years, with increasingly mature manufacturing technology and performance, new energy vehicles have stood out in the fuel market competition with excellent quality. In addition, some cities in China have implemented lottery and license plate restrictions on fuel vehicles, and many consumers have shifted their focus from fuel vehicles to new energy vehicles. At present, the country's strong subsidies for new energy vehicles have led to a thriving production and sales of new energy vehicles. In 2021, China's sales of new energy vehicles have exceeded 3.5 million units, ranking first in the world for five consecutive years in terms of production and sales



In this context, the issue of power Battery recycling recycling of new energy vehicles has also attracted social attention. At present, the power source of mainstream new energy vehicles in the market is mainly Lithium iron phosphate battery and ternary lithium battery. Generally speaking, the scrapping period of power batteries for operational new energy vehicles is 3-5 years, while for private passenger vehicles, the scrapping period is 5-8 years. Data predicts that 530000 tons of 'retired' power batteries will be produced in 2022.

Controlling the direction of power batteries after their retirement, preventing environmental pollution caused by indiscriminate disposal, and promoting the recycling, disposal, and utilization of power batteries play a positive role in promoting industrial development.

In response, the Energy Conservation and Comprehensive Utilization Department of the Ministry of Industry and Information Technology has also introduced relevant measures, requiring that the comprehensive recovery rate of nickel, cobalt, and manganese should not be less than 98%, the elemental recovery rate of lithium should not be less than 85%, and the comprehensive recovery rate of rare earth and other major valuable metals should not be less than 97%.

Taking ternary material batteries as an example, their positive electrode contains a large amount of precious metals, including cobalt accounting for 5-20%, nickel accounting for 5-12%, manganese accounting for 7-10%, lithium accounting for 2-5%, and 7% plastic. Cobalt, as a strategic resource, is widely used in various fields. However, the cycling performance of ternary batteries is poor, and the purity of nickel, cobalt, and lithium in the plasma is much higher than that of raw materials extracted from ores and mineral salts, so they are more inclined to be disassembled and utilized.

As Sodium persulfate, which has great advantages in the extraction of precious metals, its extraction process has the advantages of higher efficiency, shorter cycle, milder and safer, and plays an advantageous role in the disassembly and utilization of power batteries. Therefore, the domestic demand for persulfate is in a rapid growth stage.

In order to promote the production and practical application of Sodium persulfate, Zhanhua Chemical has seized the development opportunity of the industry and has been striving to build a national brand of persulfate in the past 20 years, becoming a key enterprise in Fujian Province.


In order to ensure the quality stability of Sodium persulfate, Zhanhua Chemical has adopted a modern management system, equipped with advanced inspection instruments, and strictly controlled the production process by professional and high-quality staff. At present, the persulfate products produced by Zhanhua Chemical are all in compliance with the 'National Standard for Industrial Grade Persulfate' for superior products. While meeting the needs of the domestic market, it is also widely exported to overseas markets, covering over 20 countries worldwide and serving over 500 customers worldwide.

Up to now, Zhanhua Chemical has become a national level 'specialized, refined, and innovative small giant' and a national level 'high-tech enterprise', with an annual production capacity of over 80000 tons of persulfate. It is a large-scale global persulfate production enterprise. The ongoing Phase III expansion project is a provincial-level key project in the 14th Five Year Plan of Fujian Province. After being put into operation, it will significantly increase the overall production capacity of the enterprise and further expand its leading advantage in the industry.


The problem of power Battery recycling recycling needs to be solved urgently, but the market is also full of chaos. Due to the differences in production equipment and processes of various recycling enterprises, as well as the different sources of raw materials, the recycling technology is complex, and the quality of precious metals extracted is uneven. In the future, Zhanhua Chemical will set an example and promote the healthy development of waste Battery recycling recycling industry by virtue of years of experience in producing Sodium persulfate.
