Abstract

Abstract: The rechargeable sodium-ion battery has become a research hotspot due to low cost and a large abundance of sodium resources. In this work, a novel nano-architecture of Cu2 Se nanoparticles imbedded in ordered mesoporous carbon (Cu2 Se@ CMK-3) was synthesized. Benefiting from the high conductivity and special nano-architecture of CMK-3 matrix, the as-synthesized Cu2 Se@ CMK-3 composite delivers a high specific discharge capacity (231 mA h g −1 ) and superior cycling stability (a capacity decay of 0.33% per cycle during 100 cycles at 0.1 C) when used as cathode in sodium-ion batteries.
