Analysis of Multiple Reaction Sequences in Flow‐Through Porous Electrodes

“…This effect has been well documented for the lead-acid system (6)(7)(8)(9)(10)(11) and is particularly damaging not only for the effects on mechanical integrity but also for its contribution to internal resistance, a factor which limits battery performance. Most notable of these is the classical problem of localized attack of segregated materials such as the eutectic structure or intermetallic compounds.…”

“…The use of fixed bed porous electrodes with a single electrode reaction has been recently reported for stripping copper (1), depositing antimony (2) and copper (3)(4)(5), carrying out redox reactions with iron (6) and ferricyanide couples (5,7,8), detecting dissolved gases (9)(10)(11), and for precipitating anionic species (12). Earlier work has been reviewed with emphasis on battery applications (13) for which a single electrode reaction is the preferred mode of operation.…”

Moreover, other effects such as active mass to grid bonding, active mass morphology, and reduced overpotentials for gassing…”
