article description
Oligomer-suspended SiO-polyethylene glycol nanoparticles are studied as porous media electrolytes. At SiOvolume fractions, , bracketing a critical value≈ 0.29, the suspensions jam and their mechanical modulus increase by more than seven orders. For >, the mean pore diameter is close to the anion size, yet the ionic conductivity remains surprisingly high and can be understood, at all , using a simple effective medium model proposed by Maxwell. SiO-polyethylene glycol hybrid electrolytes are also reported to manifest attractive electrochemical stability windows (0.3-6.3 V) and to reach a steady-state interfacial impedance when in contact with metallic lithium. © 2010 The Royal Society of Chemistry.
