Abstract:
Herein, we report on a facile and novel synthesis and multifarious characterizations of the graphene wrapped KFeSO4F (KFSF@G) for the first time. The KFSF@G electrode exhibits admirable electrochemical performance with a high average operating potential of 3.55 V and high reversible discharge capacity of 111.51 mA h g-1.
