WebMar 8, 2024 · Three different methods were used to produce α-Ni(OH)2 with higher discharge capacities than the conventional β-Ni(OH)2, specifically a batch process of co-precipitation, a continuous process of co-precipitation with a phase transformation step (initial cycling), and an overcharge at low temperature. All three methods can produce α … WebOct 5, 2024 · ABSTRACT. We report x-ray photoemission spectra (XPS) of beta-nickel hydroxide ( β -Ni (OH) 2 ). XPS spectra were measured with the Physical Electronics Model 5400 x-ray photoelectron spectrometer using unmonochromated Mg Kα x rays at two pass energy settings corresponding to analyzer energy resolutions of 1.34 and 0.54 eV.
