水系锌离子电池正极的改性策略及发展展望
Modification strategies and development prospects for positive electrodes for aqueous zinc-ion batteries
摘要
Abstract
With the implementation of the national"carbon peak"and"carbon neutrality"policies,the development of new electrochemical energy-storage technologies has become an important aspect of support for the new power system and for energy transformation.Among various energy-storage devices,aqueous zinc-ion batteries(AZIBs)are attracting widespread attention due to their abundant resources,high theoretical specific capacity,high safety,and cost effectiveness.However,their rapid development urgently requires breakthroughs in the technical challenges of electrode materials.At present,there are three common problems with positive-electrode materials for AZIBs,which make it difficult to apply them with high-performance and long endurance under complex service conditions.In this article,starting from the development history of AZIBs,we systematically elaborate on four common energy-storage mechanisms of positive-electrode materials for AZIBs through the exploration of recent relevant literature.We then summarize the inherently low conductivity,slow ion-transport speed,and poor structural stability of three common positive-electrode materials:manganese-based materials,vanadium-based materials,and organic materials.We also focus on four improvement strategies and discuss the corresponding progress,including the construction of novel microstructures,regulation of the oxygen-vacancy concentration,regulation of the interlayer structure,and increasing the material hydrophobicity.Finally,we discuss the research prospects for,and specific directions in,composite materials,expansion of the research field,and characterization-testing technology,providing references and inspiration for the design and development of high-performance AZIBs.关键词
