Applications and Recycling of Lithium-ion Batteries

Abstract

With the rise of global warming, people have turned to electricity as a means of reducing greenhouse gas emissions, and Lithium-ion batteries (LIBs) have emerged as a popular energy conservation solution. However, as the use of LIBs increases, the recycling industry is facing significant wastemanagement challenges. The decreasing content of precious metals in LIBs has led to a decline in recycling income. This article explores the application of LIBs in new energy vehicles, and evaluates the challenges faced by the recycling industry and provides suggestions for overcoming them. Currently, lithium iron phosphate, lithium nickel cobalt manganese and lithium nickel cobalt aluminum batteries have been used in new energy vehicle power batteries. The main recycle methods include direct recycling, hydrometallurgy, and pyrometallurgy. The article then suggests that improved recycling lines that use artificial intelligence and renew manufacturing standards may be beneficial solutions. By addressing these challenges, the problems associated with LIB recycling may be transformed into opportunities for the future.
