Protective Properties of Lead Coating with Tin Sublayer for Copper Current Leads of Negative Electrodes in Lead-acid Batteries

The possibility of using a two-layer coating consisting of a tin sublayer and a lead layer for protection of copper current leads of negative electrodes in lead batteries was studied. The processes occurring on reflowing of the tin coating were investigated. The dependence of the protective characteristics of the tin coating on the heat treatment mode was shown to have extrema.
