Abstract

Disclosed herein are electrode compositions comprising a homogeneous mixture comprising: a lead-containing material and a carbon additive comprising carbon black and activated carbon. A total amount of the carbon additive ranges from 0.1% to 2% by weight, relative to the total weight of the composition. The composition can have a ratio of carbon black to activated carbon ranging from 0.1:0.9 to 0.5:0.5. The activated carbon can have a d₅₀ particle size distribution ranging from 4 μm to 100 μm, and a pore volume of at least 0.7 cm³/g. Also disclosed are electrodes formed from the electrode composition, cells (e.g., lead-acid battery) comprising the electrodes/electrode compositions, and methods of making thereof.
