Abstract
An alkaline electrochemical cell having an anode including electrochemically active anode material, a cathode including electrochemically active cathode material, a separator between the anode and the cathode, and an electrolyte. The electrolyte includes a hydroxide dissolved in water. The separator in combination with the electrolyte has an initial area-specific resistance between about 100 mOhm-cm2 and about 220 mOhm-cm2.
Claims16
An alkaline electrochemical cell comprising an anode including an electrochemically active anode material, a cathode including an electrochemically active cathode material, a separator between said anode and said cathode, and an electrolyte comprising an ionically-conductive component dissolved in water, and the separator in combination with the electrolyte has an initial area-specific resistance between about 100 mOhm-cm2 and about 220 mOhm-cm2;
- wherein the anode material is selected from the group consisting of zinc, zinc alloys, cadmium, iron, and metal hydride;
- and the cathode material is selected from the group consisting of manganese oxide, manganese dioxide, electrolytic manganese dioxide (EMD), chemical manganese dioxide (CMD), high power electrolytic manganese dioxide (HP EMD), lambda manganese dioxide, silver oxide, nickel oxide, nickel oxyhydroxide, copper oxide, bismuth oxide, high-valence nickel, and mixtures thereof.
