Abstract

ABSTRACT The demand for the large-scale storage system has gained much interest. Among all the criteria for the large-scale electrical energy storage systems (EESSs), low cost ($ k Wh−1) is the focus where MnO2-based electrochemistry can be a competitive candidate. It is notable that MnO2 is one of the few materials that can be employed in various fields of EESSs: alkaline battery, supercapacitor, aqueous rechargeable lithium-ion battery, and metal-air battery. Yet, the technology still has bottlenecks and is short of commercialisation. Discovering key parameters impacting the energy storage and developing systematic characterisation methods for the MnO2 systems can benefit a wide spectrum of energy requirements. In this review, history, mechanism, bottlenecks, and solutions for using MnO2 in the four EESSs are summarised and future directions involving more in-depth mechanism studies are suggested.

电能存储系统水电解质中MnO2的机理理解综述

摘要对大规模存储系统的需求已经引起了人们的极大兴趣。在大型电能存储系统（EESS）的所有标准中，低成本（$k Wh−1）是基于MnO2的电化学可以成为竞争候选者的焦点。值得注意的是，MnO2是少数可用于EESS各个领域的材料之一：碱性电池、超级电容器、水性可充电锂离子电池和金属-空气电池。然而，这项技术仍然存在瓶颈，缺乏商业化。发现影响能量存储的关键参数并开发MnO2系统的系统表征方法可以有利于广泛的能量需求。在这篇综述中，总结了在四种EESS中使用MnO2的历史、机制、瓶颈和解决方案，并提出了涉及更深入机制研究的未来方向。
