Synthesis of catalytic materials from metal recovery processes in spent battery recycling

Abstract

Under the goal of global sustainable development, the rapid development of the new energy industry has led to the proliferation of used batteries. Recycling of batteries is the key to the sustainable development of the new energy industry, which is also in line with the concept of circular economy. And the green extraction of key metals is the core part of its development.

This study analyzes metal recovery technologies from waste batteries and assesses their potential for reuse as catalyst materials. It explores the methods, efficiency, and environmental impacts of pyrometallurgical, hydrometallurgical, mechanochemical and biotechnology processes. In addition, it assesses the feasibility of using the recovered metals to synthesize catalysts for various applications, highlighting the implications for sustainability, resource conservation and environmental protection. The study advocates the incorporation of battery metal recycling into catalyst production to mitigate environmental degradation and promote circular economy principles in energy storage.
