从“城市矿山”掘金，武汉博士唤醒废旧锂电池“二次生命”

Core Viewpoint - The article highlights the innovative research of Ding Weigang, a PhD graduate from Wuhan University of Technology, focusing on the recycling of waste lithium batteries to alleviate resource shortages and environmental pressures in the context of the growing demand for lithium batteries in electric vehicles [1][3]. Group 1: Research and Innovation - Ding Weigang is conducting research on the recycling of waste lithium batteries, utilizing electrochemical technology to recover lithium and other valuable materials from discarded batteries [1][3]. - The research addresses the limited availability of mineral resources and the environmental impact of mining by extracting metals from electronic waste, which is referred to as "urban mining" [3]. - The technology developed by Ding involves selective acid leaching to extract lithium, nickel, cobalt, and manganese from mixed electrode materials, transforming them into high-quality products suitable for battery production [4]. Group 2: Industry Context - The increasing use of lithium batteries in electric vehicles has led to a surge in lithium prices, highlighting the urgency of developing recycling technologies to mitigate resource scarcity [3]. - The research aligns with the industry's need to reduce reliance on imported materials such as cobalt and nickel, thereby enhancing resource security through domestic recycling efforts [3]. - The technology has been recognized by Greeenmei, with the company's Wuhan Research Institute director praising its ability to optimize processes and reduce production costs, marking it as a significant technological advancement for the company [4].
