Bridging Microstructure and Sodium-Ion Storage Mechanism in Hard Carbon for Sodium Ion Batteries
Xiamen University · Collaborative Innovation Center of Chemistry for Energy Materials
Abstract
Hard carbon (HC) has emerged as a strong anode candidate for sodium-ion batteries due to its high theoretical capacity and cost-effectiveness. However, its sodium storage mechanism remains contentious, and the influence of the microstructure on sodium storage performance is not yet fully understood. This study successfully correlates structural attributes with electrochemical performance, shedding light on what makes HC effective for sodium-ion storage. It is found that HC featuring larger interlayer spacing and smaller and thinner pseudographite domains is beneficial for facile Na+ intercalation. Conversely, the presence of a long-range ordered graphite structure should be avoided, which may result in the…
