Summary:Sodium ion batteries (SIBs) are expected to replace lithium ion batteries (LIBs) as the next generation of
large-scale energy storage applications because of their superior cost performance. However, the larger
ionic radius of Na+ causes a remarkable volume expansion than that of Li+ during charge and discharge,
which reduces the performance of the battery. In this work, we engineered a composite material in that
monodispersed 2 nm Sb2S3 particles are uniformly loaded into a carbon matrix (Sb2S3/CZM), which is
obtained by carbonization of a zirconium-based MOF with adsorption of Sb. The obtained composite
material has a high specific surface area in favor of mass transfer, and the porous structure can resist
many volume changes in the circulation process. Moreover, the ultrafine Sb2S3 particles are well-distribu
ted in the composite material, which increases the utilization of the active substance and is promising for
the storage of Na+. Based on its unique structure, the Sb2S3/CZM composite shows a specific capacity of
550 mA h g−1 at 100 mA g−1 and an excellent cycling stability of 88.9% retention after 1000 cycles at 3 A
g−1. The excellent electrochemical performance provides enlightenment for the rational design of hier
archical heterostructures for energy storage applications.
