Rapid Heating Technologies for Efficient Recycling of Spent Lithium-Ion Batteries

Abstract

The rapid growth of electric vehicles and portable electronics has led to a surge in lithium-ion battery (LIB) consumption, creating an urgent need for efficient and sustainable recycling solutions. Among the established recycling methods, including pyrometallurgical, hydrometallurgical, and direct recycling, thermal treatment plays a critical role. However, conventional heating techniques are often energy-intensive and time-consuming due to their low heating rates. This highlights the importance of exploring advanced rapid heating technologies for recycling spent LIBs. This review examines the role of heating in various LIB recycling processes and systematically introduces emerging rapid he..
