Rodlike FeS/SnS@N-C Core–Shell Microparticles for Lithium-Ion Batteries
Source abstract
Abstract
FeS/SnS@N-C composites were successfully synthesized through the combination of nucleation self-assembly, N-doped carbon coating, and in situ vulcanization. The experimental results show that the discharge capacitance of FeS/SnS@N-C in the lithium storage process is 796.90 mAh g –1 at 0.5 A g –1 after 200 cycles, and more importantly, the discharge capacitance can maintain 278.84 mAh g –1 at 5 A g –1 after 2000 cycles. FeS in FeS/SnS@N-C plays a key role in the electrochemical performance, which is due to the certain electronic density of states (DOS) near the Fermi level. In short, our research expands the application of transition metal sulfide composites in lithium-ion batteries.
