Title:
ELECTRODE FOR LEAD STORAGE BATTERY
Document Type and Number:
Japanese Patent JPS5380534
Kind Code:
A
Abstract:
Between 0.001 and 0.5% by weight of polytetrafluoroethylene powder is incorporated in the composite electrochemically active mass carried on the lead plates of a lead-acid storage battery. In the case of the positive electrodes, the result is to lengthen the service life in terms of cycles of charging and discharging. In the case of the negative electrodes, the effect is to raise the low-current yield and the low-temperature high-current yield. The density of the composite mass is reduced and its water-holding properties increased.
