Abstract
This article comprehensively explores the development and performance evaluation of sodium ion battery materials, aiming to promote further development of sodium ion battery technology. The introduction section first introduces the background and significance of research on sodium ion battery materials, emphasizing their important potential in replacing lithium-ion batteries and reducing energy storage costs. At the same time, it reviews the current research status of sodium ion battery materials, providing clear directions for subsequent research. In terms of positive electrode materials, this article elaborates on the preparation processes, structural design, and performance optimization strategies of three types of positive electrode materials: layered oxides, polyanions, and Prussian blue. By comparing the electrochemical performance of different materials, the intrinsic relationship between the structure and performance of positive electrode materials is revealed. In terms of negative electrode materials, the article focuses on the development and modification of three types of negative electrode materials: carbon based, alloy based, and conversion reaction based. Through preparation and characterization, structural control, and interface optimization, the cycling stability and specific capacity of negative electrode materials have been significantly improved. In addition, this article also conducted in-depth research on the development and interface regulation of electrolytes for sodium ion batteries, including composition optimization of liquid electrolytes, preparation and performance evaluation of solid electrolytes, as well as stability studies of electrode/electrolyte interfaces, providing key support for the construction of high-performance sodium ion batteries. This article systematically studies the development and performance evaluation of sodium ion battery materials, which not only provides a theoretical basis for the further development of sodium ion battery technology, but also makes positive contributions to promoting the innovation and application of energy storage technology.
