Jan 01, 2020· The measured current–voltage characteristics of LiNi 0.5 Mn 1.5 O 4 nanoparticles appeared at around 4.7–4.8 V as the reaction peak of Ni 2+ /Ni 3+ and Ni 3+ /Ni 4+. In contrast, the Mn of the Li–Ni–Mn-oxide nanoparticles synthesized in the oxygen-deficient state was less than trivalent, which caused disproportionation of Mn.
