  • Method of manufacturing active material for lead batteries
    Patent number: 4110241
    Abstract: To obtain the active material of lead batteries one of the initial components, that is, acid-resistant fibres are settled in an electric field on a horizontal continuously moving band, the fibres being oriented square to the band and subsequently the band is covered with lead powder which fills the gaps between the fibres, the thickness of the layer corresponding to the length of the synthetic fibres.
