Herein, inversed opal (IO) structures were modified with polydopamine (PDA)/inorganic coating layer as a promising separator for high-performance lithium ion battery (LIB). Precisely ordered nanoporous IO was fabricated by inverse replica of colloidal polystyrene particles and modified thereafter PDA/inorganic layer on the IO can induce hydrophilicity which improved the electrolyte uptake and ionic conductivity of separator, resulting in excellent rate capability and cycle stability. Moreover, the hybrid layer solved the safety issue at high temperature. As a result, IO separator with PDA/inorganic achieved the significantly enhanced electrochemical performance.
