A novel synthetic strategy towards NaCl-type NixCo1−xO solid solution nanoplatelets encapsulated in N-doped carbon for enhanced lithium-ion storage

NaCl-type Ni-Co oxide solid solution is expected to be a promising alternative anode material for lithium-ion batteries. However, the synthesis of solid solutions with well-defined morphology and homogeneity is still challenging. Based on a novel NixCo1−x(OH)(OCH3)@polydopamine intermediate and its topotactic thermolysis, a unique synthetic route towards NixCo1−xO solid solution (0
