A facile synthesis of FePS3@C nanocomposites and their enhanced performance in lithium-ion batteries.

FePS3@C nanocomposites are successfully synthesized by a facile two-step route. The as-synthesized samples show excellent thermal and environmental stability. As a novel anode material for lithium batteries, the FePS3@C nanocomposites exhibit a high capacity of 1000 mA h g-1 at a current density of 0.2 A g-1 and excellent reversibility over 100 cycles, indicating their promising applications in lithium storage.
