The separator consists of a polyethylene (PE) base film and two-side coating, alumina (Al 2 O 3 ) and polyvinylidene fluoride-hexafluoropropylene (PVDF-HFP) on one side, with lithium aluminum titanium phosphate (LATP) and then with polyethylene oxide (PEO) on the other. As the result, the functionalized coated separator has exhibited a remarkable performance featuring high puncture strength (480 gf) and excellent electrochemical stability (electrochemical window 5.03 V). It is observed that lithium symmetric cells in semi-solid batteries with this separator stay stable in operation for over 1000 h (0.2 mA cm −2 ).
