To improve the cycle performance of Mg metal batteries, a spinel-type MgMn2O4 (MMO) as the active material of the cathode was coated with a poly(styrene-4-sulfonyl trifluoromethylsulfonyl)imide Mg salt (PSTFSI-Mg) on the MMO surface. Coating was performed by spray drying, freeze drying, simple mixing, and one-pot spray drying. Transmission electron microscopy measurements of the resulting polymer-coated MMO were undertaken to verify the surface and the inner morphology.
