Electrochemical investigations of alkali metal intercalation reactions in titanium disulfide: the high temperature Na/Na/sub 5/ErSi/sub 4/O/sub 12//TiS/sub 2/ cell
The high temperature Na/Na/sub 5/ErSi/sub 4/O/sub 12//TiS/sub 2/ cell has been constructed and its electrochemical properties have been investigated. At 125/degree/C, the open-circuit voltage of this cell is 2.10 v. Primary discharge studies indicate that the minimum Na/sup +/ conductivity of the Na/sub 5/ErSi/sub 4/O/sub 12/ is 0.002 /OMEGA//sup -1/ cm/sup -1/ at this temperature, so that the rate of charge transport within the cell appears to be controlled by the rate of Na/sup +/ diffusion within the TiS/sub 2/. A mathematical model has been developed which predicts the current-time behavior for this kind of cell operating under alkali metal ion diffusion control within the positive plate material. 17 refs.
