Robust graphene layer modified Na2MnP2O7 as a durable high-rate and high energy cathode for Na-ion batteries
Na 2 MnP 2 O 7 has been considered as a promising cathode candidate for advanced
sodium-ion batteries due to its high potential, low cost and non-toxicity. However, the low
initial Coulombic efficiency, poor high-rate and unsatisfactory cycling ability originated from
the intrinsic inferior electronic conductivity and manganese dissolution severely hinder its
practical application. Herein, we report an approach based on a feasible high energy
vibrating activation process to fabricate a robust graphene layers (GL) modified Na 2 MnP 2 …
