<p>Comb polymers with mono-functional pendant chains grafted onto a polymer backbone for use as electrolytes in lithium batteries have been made in the past. First mono-functional pendant chains that facilitate ion transport and second mono-functional pendant chains that facilitate dissociation of lithium salts are often both used. But the density of these chains is limited by the density of graft sites on the backbone molecule. In the embodiments of the invention, as disclosed herein, inventive polymer electrolyte materials are based on comb polymers with dual-functional pendant chains. Compounds that facilitate ion transport and compounds that facilitate dissociation of lithium salts are joined together to make a dual-functional pendant group. Thus the density of functional groups within a comb polymer can be increased by as much as a factor of two or more.</p> |
