Abstract
The conductivity of a zinc negative electrode is enhanced through use of surfactant-coated carbon fibers. Carbon fibers, along with other active materials such as bismuth oxide, zinc etc., form an electronically conductive matrix in zinc negative electrodes. Zinc negative electrodes as described herein are particularly useful in nickel zinc secondary batteries.
Claims15
A method of fabricating a zinc negative electrode, the method comprising:
- (i) coating a material selected from the group consisting of lead, tin, and combinations thereof onto zinc particles comprising at least one material selected from the group consisting of zinc and zinc oxide to form coated zinc particles;
- (ii) coating carbon particles with a surfactant to make coated carbon particles;
- (iii) forming a paste from the coated zinc particles, coated carbon particles, bismuth oxide, a dispersing agent, a binding agent, and a liquid;
- and
- (iv) incorporating the paste into the zinc negative electrode.
