The by-products of lithium battery recycling have important economic value, including lithium, nickel, cobalt, manganese and other valuable metals. However, as the intermediate products of waste battery recycling, such as sodium sulfate and sodium chloride, there is no special national standard or industry standard to regulate them, which has become an obstacle to the development of battery recycling industry.
Recently, Guangdong Standardization Association issued group standards "sodium sulfate from hydrometallurgy of lithium battery waste" and "sodium chloride from hydrometallurgy of lithium battery waste", which can solve this obstacle.
The promulgation of these two group standards can ensure the quality requirements of the intermediate products of lithium battery deep recycling, such as crude sodium sulfate and sodium chloride, and these quality indicators are consistent with the relevant national regulations.
After the two groups' standards, the crude sodium sulfate and sodium chloride produced by the two groups are recycled and processed by dehydration, which can be used as industrial anhydrous sodium sulfate and sodium chloride for industry, which can meet the national standards, and once again greatly improve the utilization value of the waste lithium battery.
The standard recovery system has further standardized the recycling industry of the waste power battery, and greatly improved the recycling and utilization rate of the waste power battery.
With the steady establishment of lithium battery recovery system, the policy is gradually clear, the recovery channel is accelerated, the power battery recovery industry is gradually standardized. In the future, the development prospect of lithium battery recovery is bright.
