38 - 013Transport Properties of Lithium Hectorite-Based Composite Elec-trolytes. — Physically gelled composite electrolytes based on lithiumhectorite clay and carbonate solvents (ethylene carbonate, propylene carbonate,and dimethyl carbonate) are shown to be attractive candidates for use inrechargeable lithium-ion batteries requiring high discharge rates. Room-temperature conductivities as high as 2·10−4 S/cm are observed in thesesystems. Lithium-ion transference numbers as high as 0.98 are measured bythe dc polarization method using Li metal electrodes. — (RILEY, MICHAEL;FEDKIW, PETER S.; KHAN, SAAD A.; J. Electrochem.
