Electrode assembly, anodic stripping

The effects of mercury film electrode morphology in the anodic stripping SWV of electrochemically reversible and quasi-reversible processes were investigated experimentally [47-51], Mercury electroplated onto solid electrodes can take the form of either a uniform thin film or an assembly of microdroplets, which depends on the substrate [51 ]. At low sqtrare-wave frequencies the relationship between the net peak crrrrent and the frequency can be described by the theory developed for the thin-film electrode because the diffusion layers at the snrface of microdroplets are overlapped and the mass transfer can be approximated by the planar diffusion model [47,48],... 

The anode current collector is an annealed, perforated, nickel-plated steel pocket plate assembly. The tubes for the positive electrode are produced from perforated nickel-plated strips that are wound to produce a tube. One end is crimped and the active material poured into the open end in layers and crimped again to close the tube. A machine automaticaUy introduces the active material and tamps it into the pockets. After filling, the tubes are pressed into openings in the nickel...
