Polyelectrolytes solvated with aprotic polar solvents showing conductivities reaching values so far known only for liquid aprotic electrolytes (>1 mS cm −1 ) are presented. Nevertheless, NMR tracer diffusion data reveal alkaline ion transference numbers close to unity indicating the absence of any concentration polarization effect for the use of this class of electrolytes especially in high drain Li‐battery applications.
