View the Complete Application at the US Patent & Trademark Office
A negative electrode for a rechargeable battery comprises a zinc oxide member doped with one or more metals and thereafter coated with a conductive layer of carbon or carbon doped with an element selected from the group consisting of fluorine, nitrogen, boron, and a mixture of two or more thereof. The electrode material is prepared by admixing ZnO or doped ZnO with carbon or a carbon-based material and then heating the admixture to form ZnO with a conductive layer. The ZnO can be doped with a first metal and then a second metal.
