| 제목 | Simple Salt-Templating Approach to Design Porous Molybdenum Carbide as a Promising Anode Material for Secondary Ion Batteries |
| 초록 | Molybdenum carbide (Mo 2 C) has gained a great interest as an advanced anode material for secondary ion batteries owing to its low cost, high chemical stability, and high conductivity. However, the electrochemical performance of bulk Mo 2 C is still inferior compared to the commercial graphite. Herein, to maximize the electrochemical performance of Mo 2 C, we demonstrate a simple route to fabricate porous Mo 2 C by using crystal NaCl as porous template. The resultant porous Mo 2 C has high surface area (177.28 m2 g-1) as compared to that of bulk Mo 2 C (1.06 m2 g-1). The porous structure and 3D interconnected configuration of Mo 2 C offer larger active sites and shortened ions diffusion pathways to the electrode/electrolyte when the materials are used as anode materials for Li/Na/K ion batteries. Porous Mo 2 C can deliver a reversible discharge capacity of 560 mAh g-1 at 50 mA g-1 for LIBs, 160 mAh g-1 at 25 mA g-1 for SIBs, and 200 mAh g-1 at 20 mA g-1 for KIBs. The porous Mo 2 C exhibits excellent stability, revealing superior electrochemical activity compared to the bulk Mo 2 C. |
