Several polymorphs of layered nickel dioxide were prepared by using the chemical insertion of alkaline ions into Li 0.10 NiO 2 . We used aqueous AOH (A = Li, Na, K) solutions as reducing agents. Sodium and potassium insertion resulted in hydrated layered compounds that can be classified as γ-NiOOH with high crystallinity, while lithium insertion occurred without hydration. We discuss...
Five kinds of nickel dioxide polymorphs, Li x NiO 2 with x~0, were prepared by treating LiNiO 2 with sulfuric acid solutions, occasionally followed by low-temperature heating. Here we report their structure and properties as lithium insertion electrodes. Acid-treated Li 0.10 NiO 2 with two layered phases turned into a single-layered compound at...
