β¦ 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.

Activated carbon fiber sheets (ACF sheets) have been developed as polarizable electrodes of electric double layer capacitors. The ACF sheets were prepared by a paper-making process from activated carbon fibers (ACF), carbon fibers (CF), and pulps. The specific surface area of ACF sheets depended pro
