Abstract

Recycling spent lithium-ion batteries (LIB) has emerged as a pressing necessity for addressing resource shortages and mitigating environmental pollution. This article reviews the most advanced spent LIBs recycling technology, namely direct regeneration. Traditional recycling methods have problems with high energy consumption and secondary pollution. In contrast, direct regeneration extends battery life by repairing degraded cathode materials and retains battery energy to the maximum extent. This method includes technologies such as chemical lithiation and recycling of waste graphite. These innovative technologies improve battery cycle life, reduce energy consumption, production costs, and promote sustainable resource management. Direct regeneration technology provides new opportunities to reduce resource waste and reduce environmental pollution. It will promote the sustainable management of spent LIBs and support the development of future renewable energy technologies.
