Research on Hazardous Characteristics for Complete Discharged Li-Ion Traction Batteries

Judging from the performance of lithium ion battery materials and the techniques for battery manufacturing on the market, the world will see the booming of scrap traction batteries in the next three to five years. When the time comes, the safe transportation of these batteries is going to be an imminent problem for recycling companies. By analyzing the current polocies, laws, regulations and standards, the harzards of the used traction batteries were determined. And in order to eliminate their potential risk to human bodies and the environment a pretreatment was proposed, that is, complete discharge of the batteries. As proven in the following context, the completely discharged traction batteries no longer possess the previous dangerous/hazardous characteristics, therefore, they can be treated as general goods. Lowering the recycling cost of the batteries in the meanwhile, this method provides a solution to the conundrum of used traction batteries' tranportation.
