Simple Salt-Templating Approach to Design Porous Molybdenum Carbide as a Promising Anode Material for Secondary Ion Batteries |
| 초록 |
Molybdenum carbide (Mo2C) 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 Mo2C is still inferior compared to the commercial graphite. Herein, to maximize the electrochemical performance of Mo2C, we demonstrate a simple route to fabricate porous Mo2C by using crystal NaCl as porous template. The resultant porous Mo2C has high surface area (177.28 m2 g-1) as compared to that of bulk Mo2C (1.06 m2 g-1). The porous structure and 3D interconnected configuration of Mo2C 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 Mo2C 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 Mo2C exhibits excellent stability, revealing superior electrochemical activity compared to the bulk Mo2C. |
