The electrolytes were prepared by dispersing fumed silica in a matrix formed by methyl-capped polyethylene glycol and lithium salt. Silicas with widely different surface chemistries were synthesized in order to study the effects of surface modification, with the attached surface groups ranging from non-polar alkyl moieties (C1 or C8) to polar polyethylene oxide (PEO) oligomers (MW∼200). We find, rather surprisingly, that the conductivity is independent of the type of surface group present on the silica. Moreover, the conductivity decreases only slightly on addition of fumed silica, even at high weight fraction of solids. In contrast, the rheological properties of the composites are strongly affected by both the silica surface chemistry and weight fraction. Dynamic rheology measurements reveal that fumed silicas with silanol and octyl coverage both flocculate into gels (networks). The resulting materials are mechanically stable, with the elastic modulus of the gel being strongly dependent upon weight fraction of solids. The PEO-modified silica, in contrast, gives rise to a low-viscosity suspension where the silica units exist as distinct, non-interacting species. The findings of this study have significant implications for future work on composite electrolytes, in that we can tailor the mechanical properties of the system without affecting the electrochemical behavior.}, number={1-2}, journal={SOLID STATE IONICS}, author={Fan, J and Raghavan, SR and Yu, XY and Khan, SA and Fedkiw, PS and Hou, J and Baker, GL}, year={1998}, month={Aug}, pages={117–123} }

The composite cathodes were cast from a slurry mixture consisting of 30% NMP solvent and 70% solid (91% LiMyOx, 3% PVDF and 6% KS44 graphite) onto a 25-μm thick Al current collector. The compacted cathodes were made from the cast cathode using a laboratory press. The most compacted cathodes have the smallest impedance and the highest specific capacity and capacity-rate. Three equivalent circuits are proposed according to the effect of compaction pressure on our EIS results and work reported in the literature. The EIS results and relationship to the capacity and capacity-rate are discussed using these circuits. It appears that the ohmic resistance of the composite cathode is an important factor in the overall resistance of the cell and unfavorably affects the performance (capacity and capacity-rate) of the cathode.}, number={2}, journal={JOURNAL OF POWER SOURCES}, author={Fan, J and Fedkiw, PS}, year={1998}, month={Apr}, pages={165–173} }
