摘要:

在能源危机与温室效应日益加剧的形势下,Li-CO2电池作为一种兼具高效储能与CO2气体利用的新型器件,具有重大的研究意义。鉴于电池涉及多相反应,电子传递与物质转移主要发生于阴极,因此,Li-CO2电池阴极催化剂的设计与制备显得尤为重要。本文探讨了Li-CO2电池作为新型储能器件的优势,基于Li-CO2电池充放电反应机理的发展历程,深入探讨了目前其面临的关键挑战,如充放电电位差较大,容量衰减快和循环稳定性差等问题,将解决方案聚焦于阴极催化剂的研发,提出高效催化剂应该满足的核心条件。总结了近年来碳基非金属,贵金属和过渡金属等传统催化剂在Li-CO2电池领域的应用情况,并深入分析了各类催化剂的优势与不足;本文重点介绍了新兴的单原子催化剂与氧化还原介质研究进展,通过结构表征和理论计算证明其在Li-CO2电池领域展现出卓越的催化性能;本文深入剖析了Li-CO2电池进一步发展所面临的关键问题与严峻挑战,并对单原子催化剂未来的研究方向进行了展望,旨在为推动Li-CO2电池技术的不断进步提供有益的参考与借鉴。

Abstract:

With the increasing energy crisis and worsening greenhouse effect, the development of Li-CO2 batteries holds significant promise as a next-generation energy storage device with high efficiency and CO2 utilization. The operation of Li-CO2 batteries involves complex multiphase reactions coupled with electron/substance transfer, primarily occurring at the cathode. Therefore, the design and synthesis of effective cathode catalysts are crucial for enhancing battery performance. This study reviews the advantages of Li-CO2 batteries as new energy storage devices and examines their electrochemical reaction mechanisms. The key challenges, such as the large potential gap, rapid capacity degradation, and poor cycling stability are discussed. This review focuses on cathode material research and outlines the key conditions for high-efficiency catalysts. Among the conventional catalysts, such as carbon-based non-metallic, noble metal, and transition metal, the emerging single-atom catalysts (SACs) and redox mediators are highlighted, demonstrating excellent catalytic performance as proven via characterization and theoretical calculations. Considering the future challenges in Li-CO2 batteries, more research should be done in SACs to promote continuous technological progress in this field.
