High energy/power density nickel oxide/hydroxide materials and nickel cobalt oxide/hydroxide materials and production thereof

摘要

According to one embodiment, a method includes forming a nickel oxide/hydroxide active film onto a substrate from a solution including a nickelous salt and an electrolyte, where the nickel oxide/hydroxide active film has a physical characteristic of maintaining greater than about 80% charge over greater than 500 charge/discharge cycles, and wherein the nickel oxide/hydroxide active film has a physical characteristic of storing electrons at greater than about 0.5 electron per nickel atom.
