Abstract
Methods are disclosed in which an electrically conductive substrate is immersed into an electrodepositable composition, the substrate serving as an electrode in an electrical circuit comprising the electrode and a counter-electrode immersed in the composition, a coating being applied onto or over at least a portion of the substrate as electric current is passed between the electrodes. The electrodepositable composition comprises: (a) an aqueous medium; (b) an ionic resin; and (c) solid particles.
Claims9
A method of producing an electrode for a lithium on battery comprising:
- immersing an electrically conductive substrate into an electrodepositable composition, the substrate serving as the electrode in an electrical circuit comprising the electrode and a counter-electrode immersed in the composition, a coating being applied onto or over at least a portion of the substrate as electric current is passed between the electrodes,
- the electrodepositable composition 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 solid particles to ionic resin of at least 17:1 and the weight ratio of lithium-containing particles to electrically conductive particles being at least 3:1.
