Abstract
The present invention is directed to electrodepositable compositions comprising: (a) an aqueous medium; (b) an ionic resin; and (c) solid particles comprising: (i) lithium-containing particles, and (ii) electrically conductive particles, wherein the composition has a weight ratio of the solid particles to the ionic resin of at least 17:1, and wherein the weight ratio of the lithium-containing particles to the electrically conductive particles is at least 3:1. The present invention is additionally directed to a battery electrode comprising a substrate and a coating applied to a surface of the substrate. The coating is deposited from the electrodepositable composition described above.
