Used power batteries (such as ternary lithium and lithium iron phosphate batteries) contain various metal resources like lithium, cobalt, and nickel. Efficient extraction of these metals not only enables resource recycling but also helps avoid environmental pollution. In the treatment process, the selection of oxidizing agents is critical. Sodium persulfate and sodium hypochlorite, as two common oxidizing agents, exhibit significant differences in practical applications. The following provides a comparative analysis from three dimensions: metal extraction efficiency, environmental impact, and maintenance of system purity. I. Metal Extraction Efficiency: Selectivity Determines Recovery Value In used battery treatment, achieving precise extraction of specific metals is key to enhancing recovery value. Sodium Hypochlorite: Its oxidizing capacity is significantly influenced by pH. If not properly controlled, minor fluctuations in pH can lead to co-oxidation of various metal ions, causing target metals and impurity metals to be leached together. This complicates subsequent separation and purification steps, increasing costs and potentially reducing the purity and value of the recovered metals. Sodium Persulfate: Particularly after activation, it exhibits a stronger oxidation potential. By precisely controlling key conditions such as pH and temperature, the sulfate radicals generated after activation achieve optimal stability. This enables efficient oxidation of target metals while reducing the dissolution of impurity metals. Moreover, it offers higher pH tolerance (±0.5 fluctuations do not affect core performance), making process operations easier to manage. This approach effectively minimizes the dissolution of non-target metals, creating favorable conditions for subsequent high-purity metal recovery and thereby enhancing the economic efficiency of the entire recycling process. II. Environmental Impact: Eco-Friendliness Relates to Sustainable Development Environmental protection is a fundamental principle that must be upheld in used battery treatment. The characteristics of the by-products from oxidizing agents directly affect the environmental performance of the treatment process. Sodium Hypochlorite: During reactions, it may produce chlorine-containing by-products such as chlorine gas and chlorates. These substances exhibit high biotoxicity and can cause severe environmental harm if not properly managed. Comprehensive exhaust gas absorption and wastewater treatment facilities are required, increasing subsequent environmental costs. Sodium Persulfate: Its main reaction products are sulfates. Although high concentrations of sulfates require proper treatment to prevent water salinization, their environmental toxicity and corrosiveness are generally lower than chlorine-containing pollutants. The treatment process is relatively simpler, offering advantages in overall environmental risk and control costs, making it more aligned with green treatment requirements. III. Maintenance of System Purity: Impurity Control Ensures Subsequent Processes In used battery treatment systems, the introduction of impurities can adversely affect subsequent processes such as metal separation and purification. Sodium Hypochlorite: While introducing active components, it also introduces chloride ions (Cl⁻) into the system. Chloride ions readily form complexes or insoluble salts with various metal ions, altering the solution's chemical environment and significantly increasing the difficulty of subsequent separation and purification, potentially affecting product purity. Sodium Persulfate: It introduces sulfate ions (SO₄²⁻) into the system. Compared to chloride ions, sulfates generally cause less interference in subsequent separation steps such as precipitation and solvent extraction, making them easier to control and manage. This helps maintain the stability of the process system and the purity of the final product. IV.  Building a Solid Foundation for Sodium Persulfate Applications with High-Quality Products In the practical application of sodium persulfate, product quality is a critical prerequisite for its effectiveness in areas like used battery treatment. Demonstrates industry-leading capabilities in this regard. The company has established a stringent quality control system covering the entire production process. Starting from raw material procurement, high-purity materials are carefully selected to ensure stability from the initial production stage.

Conclusion In the field of used battery treatment, sodium persulfate demonstrates clear advantages in metal extraction selectivity, environmental friendliness, and maintenance of system purity, making it more aligned with the current needs of efficient resource recovery and green treatment. Fujian Zhanhua Chemical, with its high-purity, low-impurity sodium persulfate products, provides a solid foundation for its widespread application in used battery treatment and other areas, supporting the industry's progress toward greener and more efficient practices.

In today's society, with the rapid advancement of technology, batteries are being used more widely than ever—from everyday electronic devices to electric vehicles—they have become an indispensable energy carrier. However, the massive generation of used batteries has also brought severe environmental challenges and resource wastage issues. How to efficiently and environmentally treat used batteries has become a focus of social concern. Among various treatment reagents, sodium persulfate has shown significant advantages in the field of used battery treatment due to its unique chemical properties. I. Mild Reaction, Reduced Equipment Wear Traditional used battery treatment often relies on highly corrosive reagents such as strong acids and alkalis. These reagents react violently with battery materials, causing severe corrosion to processing equipment. With prolonged use, key components of the equipment are prone to damage, which not only increases maintenance frequency but may also lead to premature equipment failure, significantly raising processing costs. In contrast, sodium persulfate, after proper activation (e.g., heating or adding catalysts), can efficiently decompose battery materials through strong oxidizing free radicals under weakly acidic conditions and relatively low temperatures. These controllable reaction conditions effectively reduce the risk of corrosion to processing equipment. The sodium persulfate produced by Fujian Zhanhua Chemical, owing to its high purity and stability, ensures efficient reactions under mild conditions, further minimizing equipment wear. II. Efficient Leaching, Improved Resource Recovery Efficiency Used batteries contain various valuable metal resources such as lithium, nickel, and cobalt. Effective recovery not only alleviates resource shortages but also offers economic benefits. In used battery treatment, sodium persulfate demonstrates excellent leaching capabilities for these valuable metals. In specific treatment processes, sodium persulfate often works synergistically with dilute acids (e.g., sulfuric acid) to help destroy the crystal structure of cathode materials and oxidize metals like cobalt and manganese, significantly enhancing the acid's leaching effect on lithium, nickel, cobalt, and other metals. This creates favorable conditions for subsequent metal extraction and purification. Compared to some traditional leaching reagents, sodium persulfate achieves higher metal recovery rates in a shorter time, greatly improving resource recovery efficiency and enabling more efficient utilization of limited resources. III. Environmental Friendliness, Reduced Secondary Pollution Environmental protection is a core principle of used battery treatment. Traditional treatment methods are prone to causing secondary pollution: for example, pyrometallurgy emits toxic sulfur dioxide exhaust gases, conventional acid leaching produces high-concentration acidic wastewater containing heavy metals, and the residual slag still contains toxic heavy metals, making subsequent treatment difficult and costly. Sodium persulfate, however, exhibits clear environmental advantages in used battery treatment. On one hand, the reaction process does not generate harmful gases such as sulfur dioxide or nitrogen oxides, reducing atmospheric pollution at the source. On the other hand, its by-products are mainly sulfates, which, although increasing wastewater salinity, can be easily removed by adding lime for precipitation. Overall, the environmental burden is significantly lower compared to traditional methods, greatly reducing the risk of secondary pollution and providing strong support for the green treatment of used batteries. Conclusion Sodium persulfate, with its numerous advantages such as mild reaction conditions, efficient leaching, and environmental friendliness, holds great potential in the field of used battery treatment.  as the world's largest producer of persulfates, has an annual sodium persulfate production capacity of 50,000 tons, which will expand to 90,000 tons after the completion of its third-phase project.
