The present invention is directed to an electrolyte comprising a first phase including a porous organic microparticle; and a second phase including an ethylene oxide-containing polymer (i.e., an EOP); wherein the second phase is a continuous phase. The polymeric electrolyte compositions preferably also includes a lithium salt and optionally a solvent. The polymeric electrolyte composition may have a shear modulus, G′, measured at 1 rad/sec and about 30° C. and a conductivity, σ, measured at about 30° C., such that i) G′-σ is greater than about 200 (S/cm)(dynes/cm2); and ii) G′ is from about 104 to about 1010 dynes/cm2.
