Abstract

A facile and industry-accepted dealloying method was used to synthesize Mn3O4 particles, which were then employed to prepare sulfur/Mn3O4 (S/Mn3O4) composites as cathode materials for lithium-sulfur batteries. The composites delivered initial discharge capacity reaching up 1184 mAhÃ‚Â·gâˆ’1 at 0.1 C with capacity retention of 679 mAhÃ‚Â·gâˆ’1 after 150 cycles. In addition, even at 2 C, the lithium/sulfur battery with S/Mn3O4 cathode delivered high reversible discharge capacity of 540 mAh gâˆ’1, demonstrating excellent rate capability.
