Mo2C: A Potential Anode Material for Lithium and Sodium Ion Battery

Mo2C emebded in carbon and reduced graphene oxide has been explored as an anode material for lithium as well as sodium ion batteries. This suitably designed anode demonstrates capacity around 650 mAh/g in case of lithium ion battery and ~450 mAh/g capacity at 50 mA/g current density in case of sodium ion battery. The added extra carbon and reduced graphene oxide provide desired electronic conductivity and cushionnig affect to minimize the volume variation due to intercalation and deintercalation. Mo2C/C/rGO anode could retain 645 mAh/g capacity after 1500 cycles when used as anode material for lithium ion battery. On the other hand, its retention is around 96.4% of its intial capacity after 750 cycles as sodium ion battery anode material. The excellent retention of capacity in both cases arises due to this specially designed electrode. The results shed light on potential of this material as futuristic anode material for lithium as well as sodium ion battery.
