The gray industry chain of 3C power bank is formed, making money while transferring risks.

The person in charge of a lithium battery recycling company told reporters that recycled power banks are generally scrapped as electronic waste. After being cracked and the battery cells soaked in water, the processed battery cells are then transported to downstream dismantling companies for crushing, thermal decomposition, and other processes, ultimately separating out materials such as iron powder and graphite to make new batteries. However, the entire process is long and the cost is relatively high. Reselling these airport power banks through the second-hand channel can yield much higher profits. If purchased individually from the recycling company, they can be sold for around 6 yuan each, and when resold on the second-hand platform, those in good condition can be sold for over 40 yuan. Wholesale costs by the ton are lower and more profitable.
