Claim 15:
16. A negative electrode for a lead-acid battery, the negative electrode comprising:
a negative current collector and a negative electrochemically active material on the negative current collector;
the negative electrochemically active material, having a composition with a normalized CO2 savings of greater than 2 g CO2/km, the composition comprises a leady oxide, 0.1-0.3 wt % of a synthetic organic material, 0.1-0.3 wt % of a first conductive carbon, 0.1-0.3 wt % of a second conductive carbon, and 0.5-1.5 wt % of a fine particle barium sulfate, wt % being an amount relative to dry leady oxide used in the negative electrochemically active material;
the first conductive carbon being activated carbon and the second conductive carbon being graphite and each having a surface area between 100 m2/g and 200 m2/g; and
the synthetic organic material comprising surface active molecules to provide for reduced deposition of a lead as a non-porous layer proximate to the negative electrode.
