Mechanism of Co3O4/graphene catalytic activity in LiaO2 batteries using carbonate based electrolytes
We synthesized a hybrid graphene/Co3O4 catalyst by a simple chemical reduction method, and demonstrated that a LiaO2 cell with the hybrid catalyst delivers a highly reversible capacity. We examined the role of the catalyst in LiaO2 batteries and through careful analyses of the reactions in the batte...

| description | We synthesized a hybrid graphene/Co3O4 catalyst by a simple chemical reduction method, and demonstrated that a LiaO2 cell with the hybrid catalyst delivers a highly reversible capacity. We examined the role of the catalyst in LiaO2 batteries and through careful analyses of the reactions in the battery, we found that the reaction path fundamentally changes with the use of catalyst, and propose a mechanism of how the rechargeability is improved in LiaO2 batteries. |
