Composite polyether electrolytes filled with oriented MMT layers in perpendicular (M⊥) or parallel (M//) to the film surface were successfully obtained by the application of strong magnetic field. The ionic conductivity of the M⊥ composite with 5 wt% of Li-MMT was 1.2 × 10−5 S cm−1 at 30 °C, and the value was more than six times greater than that of the original electrolyte (PMEO10LiClO4). We concluded that the ionic migration on the layer of oriented MMT has a crucial role to increase the conductivity with lower activation energy.
