Heterostructures are attracting increasing attention in the field of sodium‐ion batteries. However, it is still unclear whether any two monophase components can be used to construct a high‐performance heterostructure for sodium‐ion batteries, as well as the kind of heterostructures that can boost electrochemical performances. In this study, based on classical semiconductor theories on antiblocking...
To prepare highly N‐doped carbon materials (HNCs) as well as to determine the influence of N dopants on Na‐ion storage performance, hexamine‐based metal–organic frameworks are employed as new and efficient precursors in the preparation of HNCs. The HNCs possess reversible capacities as high as 160 and 142 mA h g−1 at 2 A g−1 (≈8 C) and 5 A g−1 (≈20 C), respectively, and maintain values of 145 and...
