摘　　要：随着世界各国对于化石燃料的过度依赖,导致大气中的CO_(2)气体排放愈演愈烈。Li-CO_(2)电池作为一种清洁能源,可以捕获空气中的CO_(2)转化为电能和具有高能量密度等特点,被称为是下一代能源存储设备。然而,由于Li-CO_(2)电池在放电过程中产生一种宽带隙难溶物Li_(2)CO(3),导致电池在充电过程需要较高的充电电压进行分解,所以研究人员着重于开发可以有效分解放电产物的正极材料。本文归纳了锂-二氧化碳电池非均相正极材料的研究进展,对锂-二氧化碳电池的非均相正极催化剂的发展状况进行了介绍,对目前面临的挑战以及未来发展的趋势做出了归纳和总结,为开发高效可逆的锂-二氧化碳电池提供参考。As countries around the world rely excessively on fossil fuels,leading to increasing CO_(2) gas e-missions in the atmosphere,Li-CO_(2) batteries,as a clean energy source,can capture CO_(2) in the air and convert it into electricity and have high energy density,and are known as the next generation of energy storage devices.However,since Li-CO_(2) batteries produce a wide band gap insoluble substance Li_(2)CO(3) during discharge,which leads to the need for higher charging voltage for decomposition during charging,researchers have focused on developing cathode materials that can effectively decompose the discharge products.This paper summarizes the research progress of heterogeneous cathode materials for Li-CO_(2) batteries,and introduces the characteristics of heterogeneous cathode materials,and summarizes the cur-rent status and challenges of their development as well as the future development trends.This paper pro-vides a reference for the development of efficient and reversible Li-CO_(2) batteries.
