Abstract

Sodium-ion batteries (SIBs) are promising alternatives to lithium-ion batteries (LIBs) in view of the natural abundance and low cost of sodium resource. Constructing high-performance anode is essential and challenging for the futuristic SIBs development. Transition metal sulfides have been proved as promising anode materials for SIBs due to their large specific capacities. Here, in situ assembly of cobalt sulfide nanosheets on stainless steel mesh (SSM/CoS) as a binder-free anode for SIBs is carried out through a facile electrochemical deposition procedure. The SSM/CoS products are directly used as anode electrodes without addition of binder and conductive additives. As a result, a high capacity of 313 mAh g⁻¹ is obtained at a current density of 50 mA g⁻¹ over 100 cycles.
