โœฆ Synopsis

Electrical power supply and utilization (scientific, technical)

increases with increasing sweep rate and reaches up to 90% for Li+ and 65% for C104-ions at a sweep rate of 40 mV s-'. The formation of a passive film decreases the IDE during the first intercalation/de-intercalation

cycle. The open-circuit potential for a battery assembly involving these two electrodes is in the range 3.8 to 4.0 V.
