Aliphatic polycarbonate-type solid polymer electrolytes (SPEs) exhibit excellent electrochemical properties with high Li salt concentrations. A polycarbonate-based copolymer was developed by copolymerization with poly(decamethylene carbonate) [P(DMC)], pentaerythritol, triethylene glycol (TEG), 3,9-bis(1,1-dimethyl-2-hydroxyethyl)-2,4,8,10-tetraoxaspiro[5.5]undecane (spiroglycol, SPG) and was evaluated as an SPE.

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.
