Abstract
A method of making an electrode for a lead acid battery which comprises compressing an active material composition into adherent contact with an apertured electrical conductor characterized in that compression is applied to the active material and electrical conductor so as to compress the active material to planar form adherent to the conductor except in the region where it is wished to form an aperture through the active material where compression is not applied or is applied to a lesser extent such that the active material can be readily displaced from the non-compressed region by means which do not displace the active material from the remainder of the compressed electrode.
