SET-LRP polymerization of acrylic monomers under acidic conditions is described. The source of the acidity may be the solvent (e.g., an acetic acid-containing solvent) or in the monomer content (e.g., acrylic acid or methacrylic acid, optionally in combination with other monomers such as methyl methacrylate).

Electrode structures and electrochemical cells are provided. The electrode structures and/or electrochemical cells described herein may include one or more protective layers comprising a polymer layer and/or a gel polymer electrolyte layer. The polymer layer may be formed from the copolymerization of an olefinic monomer comprising at least one electron withdrawing group and an olefinic comonomer comprising at least one electron donating group. Methods for forming polymer layers are also provided.

Polymers for use as protective layers and other components in electrochemical cells

Gel electrolytes, especially gel electrolytes for electrochemical cells, are generally described. In some embodiments, the gel electrolyte layers comprise components a) to c).
