Research on the recycling methods for lithium-ion batteries in the electric vehicle industry

Abstract

The accelerating threat of climate change has spotlighted the imperative for greener transportation solutions, resulting in the swift transition to electric vehicles (EVs). An essential aspect of this transformation is the integration of lithium-ion batteries as energy storage. However, the subsequent challenge of managing end-of-life batteries has underscored the urgency for efficient recycling strategies to mitigate environmental risks and economic losses. By researching current valuable articles, this article gives an overview of the current challenges in recycling lithium-ion batteries, including issues with electrode materials, ageing, and safety concerns, as well as various recycling techniques explored in response to these challenges, such as pyrometallurgical and hydrometallurgical processes, direct recycling, and emerging biological recycling methods.
