✦ Synopsis

The V60i3 electrode was tested in a nonaqueous lithium cell using 1M LiAsF, in propylene carbonate-acetonitrile mixture as the electrolyte. It was shown that incorporation of acetylene black in the V601s electrodes improved cell performance in terms of active material utilisation. Also, cells using hydrophilic microporous polypropylene separators, e.g., Celgard 5511 and 3501, displayed less resistive losses enabling larger charge/discharge rates to be used. Voltage changes in the cell were shown to be. controlled almost entirely by the V60i3 electrode. Analysis of the exhausted V60i3 electrodes showed that they contained at least 4 moles of lithium per mole of V60i3.
