  • Publication number: 20070248880
    Abstract: Alkaline electrochemical cells having extended service life and acceptable gassing and corrosion properties are disclosed. An amphoteric surfactant can be incorporated into the gelled anode mixture of an alkaline electrochemical cell, optionally with an organic phosphate ester surfactant or a sulfonic acid type organic surfactant or both. Zinc particles having a defined distribution of particle sizes can also be incorporated into a zinc anode. The electrolyte included, in the anode mixture can have a reduced hydroxide concentration.

  • Patent number: 6872489
    Abstract: A sulfonic acid type organic surfactant is incorporated into the gelled anode of an alkaline electrochemical cell, optionally with an organic phosphate ester surfactant. When the two surfactants are provided in a gelled anode in combination, discharge leakage is reduced and gel gassing is suppressed relative to that of gels lacking both surfactants. Additionally, cell discharge performance is improved relative to that of cells lacking both surfactant additives.
    Type: Grant
