We present the synthesis, characterization, and electrode behavior of LiNi 0.5 Mn 1.5 O 4 spinels prepared by the wet-chemical method via citrate precursors. The phase evolution was studied as a function of nickel substitution and upon intercalation and deintercalation of Li ions. Characterization methods include X-ray diffraction, SEM, Raman, Fourier transform infrared, superconducting quantum interference device, and electron spin resonance.

“…34,35 Previously we characterized the structural properties of Li from the neutron diffraction measurements. 36 And one of the results showed that, with the extraction of Li from LNMO, the amount of oxygen decreased in such a way that both the amount and the oxidation state of Ni and Mn cations are taken into account.…”

We have investigated the temperature-dependent oxygen behavior in the lithium battery cathode LixNi0.5Mn1.5O4 (LNMO) materials in the temperature range 30-1000 °C. As the temperature increases, oxygen release occurs and the change of crystal structures from the face centered cubic spinel at 30 °C to other phases follows. The amount of released oxygen and the changed crystalline phases are dependent on Li content and temperature. These phenomena are reversible against temperature in air, but not in vacuum and argon gas environments. This study illustrates the important role of temperature and atmospheric environments in synthesizing the LNMO battery materials.

“…However, it is difficult to obtain higher active material LiNi 0.5 Mn 1.5 O 4 due to the substantial Li/Ni disorder 39) or structural impurity. 17),40), 41) It is important to synthetize pure phase LiNi 0.5 Mn 1.5 O 4 due to the presence of non-stoichiometric spinel which deteriorates its electrochemical performance. In this work, the structural and electrochemical properties of LiNi 0.5 Mn 1.5 O 4 spinel by a simple wet chemical method was studied.…”

5 V cathode material LiNi 0.5 Mn 1.5 O 4 was synthetized by a simple wet chemical reaction using acetates as precursor's materials. Cathode active materials were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), Raman spectroscopy, X-ray photoelectron spectroscopy (XPS) and Inductively Coupled Plasma (ICP). Electrochemical properties of active materials were evaluated through chargedischarge tests with operation voltage between 3.5 to 4.9 V at 0.3 C. The synthetized sample with high amount of Mn/Ni precursor (LMNO-1) shows a higher first discharge capacity but a faster degradation after 3 cycles. This behavior should be due to the lack of Mn substitute by Ni and therefore more significant Jahn Teller effect as shown by Raman, ICP and XPS results.
