Abstract
In this study, the structural design and performance optimization of sodium ion battery anode materials are deeply discussed. In the current field of energy storage, sodium ion battery has attracted much attention due to its rich sodium resources and low cost, but the improvement of the performance of its cathode materials is still a research hotspot. This study aims to improve the sodium storage properties and cycle stability of cathode materials of sodium ion batteries through innovative structural design. In terms of research method, we used advanced material preparation techniques, combined with theoretical calculation and experimental verification, to systematically study the electrochemical properties of cathode materials with different structures. The results show that the well-designed cathode material structure can effectively improve the diffusion rate and embedding / stripping reversibility of sodium ions, and then significantly improve the capacity retention rate and energy density of the battery. The main contribution of this study is to reveal the internal connection between structural design and the performance of cathode materials, which provides theoretical support and technical guidance for the practical application of sodium ion batteries.
