摘要
受益于丰富的矿产资源、超高的理论容量和卓越的安全性,水系锌电池成为下一代储能设备的有力竞争者。作为锌电池理想的正极材料候选者,近年来钴基电极材料因其高输出电压、高理论容量和优异的氧化还原能力(Co^(2+)←→Co^(3+)←→Co^(4+))而受到越来越多的关注。虽然研究者对应用于锌空气电池的钴基催化剂进行了文献综述,但是主要集中在单一催化方向,缺乏关于钴基电极材料多功能特性的系统总结。本文介绍了钴基正极材料在锌电池中的多功能特性,结合其氧化还原和氧催化两方面能力,从锌钴电池拓展到复合锌钴电池体系。然后,从两种电池体系中的充放电机理出发,详细介绍了当前锌钴电池中钴基材料的优化策略,以及复合锌钴电池中电极/电解液三相界面的设计方案。最后,本文介绍了当前研究的不足,并对未来研究方向进行了展望。
Benefiting from abundant mineral resources,ultra-high theoretical capacity and excellent safety,aqueous zinc batteries have become a strong contender for next-generation energy storage devices.As an ideal cathode material candidate for zinc batteries,cobalt-based electrode materials have received increasing attention in recent years due to their high output voltage,high theoretical capacity and excellent redox ability(Co^(2+)←→Co^(3+)←→Co^(4+)).Although cobalt-based catalysts applied to zinc-air batteries have been reviewed by researchers,they mainly focus on a single catalytic direction,and a systematic summary of the multifunctional properties of cobalt-based electrode materials is lacking.This review introduces the application of multifunctional properties of cobalt-based cathode materials in zinc batteries,combining both their redox and oxygen catalysis capabilities,expanding from zinc-cobalt batteries to zinc-cobalt hybrid systems.Then,the charging and discharging mechanisms in the two battery systems are introduced,following by the current optimization strategies of cobalt-based materials in zinc-cobalt batteries and the design of electrode/electrolyte three-phase interface in zinc-cobalt hybrid batteries.Finally,this paper introduces the shortcomings of the current research and provides an outlook on future research.
