Ways To Utilize Wasted Batteries

The current use of lithium batteries is gradually increasing, especially the global number of lithium-ion batteries used in energy storage systems and other applications is steadily rising, all of which demonstrates that all future lithium batteries must have sustainable recycling pathways. Recycling companies need to explore new ways to cope with new challenges in order to better recycle used batteries and alleviate the shortage of raw materials for batteries.

Generally speaking, the recycling of used batteries is divided into two ways. One is the gradient utilization, which refers to the power battery retired from the market, although it can not continue to provide power for new energy vehicles, but it can also be used as an energy storage battery. The other is the use of lithium battery recycling equipment degree used batteries for dismantling and crushing recycling.

1 The used battery echelon use

(1) Battery classification and testing: According to the state and performance of the battery, the categorized batteries are tested, including voltage, current, capacity and resistance and other parameters, as well as the appearance and internal structure of the battery.

(2) Battery disassembly and separation: collect and process positive and negative materials, diaphragm, electrolyte and other materials in the battery separately.

(3) Battery reorganization and testing: after reassembling the materials into new batteries or batteries with higher capacity, it is necessary to test them to verify their performance and ensure safety.

2 Crushing and recycling of used batteries

(1) Discharge treatment: used batteries still retain a certain amount of power, direct crushing will have certain risks, therefore, the lithium battery should be discharged first.

(2) Crushing and sorting: The discharged lithium batteries are sent to the lithium battery recycling equipment through the conveyor belt, and after many crushing of the lithium battery recycling equipment, as well as airflow sorting, magnetic sorting, vibration sorting and copper-aluminum specific gravity must be selected for a number of screenings, and finally you can get the black powder, copper and aluminum, as well as plastic diaphragms and iron shells and other materials.

(3) Recycling These separated resources can be put into production again, realizing the goal of resource recycling.
