As a promising candidate for large‐scale energy storage, sodium‐ion batteries (SIBs) have superiority due to their low cost and abundance as a resource. Herein, homogeneous Sb2Se3 nanocrystallites embedded in carbon nanofibers (Sb2Se3/CNFs) by electrospinning and selenization treatment are prepared. The obtained Sb2Se3/CNFs exhibit good cycling performance, high reversible capacity, and excellent...
Carbonaceous materials exhibit promising application in electrochemical energy storage especially for hollow or porous structure due to the fascinating and outstanding properties. Although there has been achieved good progress, controllable synthesis of hollow or porous carbons with uniform morphology by a green and easy way is still a challenge. Herein, a new artful and green approach is designed...
Hard carbons are actively developed as a promising anode material for sodium ion batteries (SIBs). However, their sodium storage mechanism is poorly understood, leading to difficulties in design and development of high‐performance hard carbon anode materials. In this work, hollow carbon spheres (HCSs) with different shell thickness as a model material to investigate the correlation between the microstructural...
Mesocarbon microbeads (MCMB) are highly desirable as anode materials for rechargeable potassium ion batteries (PIBs) due to their commercially availability, high stability and low‐cost. However, their charge storage and interfacial mechanisms are still unclear. In this work, the intercalation mechanisms and the solid‐electrolyte‐interphase (SEI) formation of the MCMB in four different electrolytes...
