An electrolyte composition comprising (i) a block copolymer, (ii) an organic electrolyte (eg, an ionic liquid), and (iii) a lithium salt, wherein the block copolymer comprises a non-ionic block and an ionic block. And such non-ionic blocks include polymerized moieties of hydrophobic monomers, and these ionic blocks are polymerized monomeric residues covalently coupled thereto, (a) as pendant organic ionic liquid cations, such pendant organic The ionic liquid cation is a pendant organic ionic liquid cation having a counter anion, (b) a pendant anionic moiety, such a pendant anionic moiety is a pendant anionic moiety having a counter cation, or (c) their Included with combinations, these electrolyte compositions have at least two glass transition temperature (Tg) values. |
