摘要:

水系电池以其安全性高、环境友好、离子导电率高等优点,在规模储能领域展现出良好的应用前景。电荷载流子是二次电池关键的组成部分,决定着电池的机制和性能。相较于被广泛研究的金属离子作为载流子的二次电池,以非金属阳离子,如NH4+、H+、H3O+,作为电荷传输载体的研究却相对较少。与金属离子作为载流子相比,非金属离子载流子通常具有更小的水合离子半径、更低的摩尔质量,因此往往展现出更高的扩散速率与较长的循环寿命,且其制造成本更为低廉。然而,开发适于储存非金属离子的电极材料仍面临诸多挑战。本文对近几年相关研究报道进行总结。首先,介绍并讨论了非金属离子与金属离子作为载流子之间的差异;随后,总结了基于质子、水合氢离子、铵根离子和其他非金属载流子水系电池的最新研究进展;重点分析了由非金属离子存储所诱发新的电池化学与反应机制。最后,综合分析,认为通过材料结构优化工程,并且扩大电解液的工作电压区间,是有效提升水系非金属离子电池性能的必要途径之一。

Abstract:

Aqueous batteries have attracted interest due to their environmental friendliness, safety, and low cost. The charge carrier is an important component of rechargeable batteries, affecting the reaction mechanism and performance. Non-metallic cations such as NH4+, H+, H3O+ have received little attention in comparison to aqueous batteries that use metal-ion charge carriers. Compared with metal-ion charge carriers, non-metallic cations with smaller ionic radius and lower molar mass, showing higher ion diffusion rate, long cycling life, and low manufacturing costs. However, developing suitable cathode electrode materials for the insertion of non-metal charge carriers remains a challenge. In this section, we reviewed and investigated recent references in the field. First, we introduced and compared the differences between metal charge carriers and non-metal charge carriers; second, we summarized the most recent advances in the exploration and development of cathode materials for aqueous batteries with non-metallic charge carriers. The new proposed battery chemistry and reaction mechanism will be highlighted and introduced. To summarize, we proposed that optimizing the structure of electrolytes and expanding the voltage range of electrolytes could significantly improve the electrochemical performance of aqueous non-metallic batteries.
