The effect of reduction potential on charge/discharge reactions on porous lead-bismuth electrodes (positives)
- 27 Downloads
A series of discharge experiments were performed from the PbO2/O2 region to various reduction potentials using the potential step technique. Two distinct potential ranges were observed, one which occurs at potentials between 1050 and 1100 mV and the second, where there was a much larger output of capacity between 400 and 700 mV. Between these two regions there is a plateau where the relatively small output in capacity during discharge experiments enables almost complete recharging to be effected. The data presented here shows that once the electrode has entered the second reduction region it is virtually impossible to recharge the electrode using this experimental technique.
