| Abstract Scope |
The lithium-ion batteries used in electric vehicle are composed of one pack. This pack is composed of several modules and each module is composed of several cells. The weight of battery pack is above 400 kg but the weight percent of cell is only 60%. The other 40% is not lithium-ion cells but another components such as BMS(battery management system), PRA(power relay assembly), safety plug, cable, cooling system and pack case. Recycling technologies for valuable metals such as cobalt, nickel, manganese and lithium are now commercialized but non-battery components in battery pack of electric vehicles are not fully recycled. In order to complete the recycling of spent battery pack in electric vehicles, recycling of non-battery components is necessary in addition to lithium-ion cell recycling. So in this study, we introduced the physical treatment processes such as dismantlement, crushing, grinding, magnetic separation and size separation for non-battery components recycling. |
