Bipolar electroder for head accumulator.

摘要

Bipolar electrode for Pb-PbO2 storage batteries consists essentially of a conductive membrane and of active materials retained on the membrane. The membrane consists of a strip of an alloy of the stainless steel type or of a sheet of a composite of the felt or sieve type comprising chemically inert nonmetallic fibres occupying more than 50 % of the volume of the membrane. This membrane is coated with a deposit of lead or lead alloy.
