“…53 A big advantage of the technique was that a small particle size could be achieved when the final dried solid LiMn 2 O 4 powder, made from the spray technique, obtained particles that ranged between 75 and 1250 nm. 54 Taniguchi et al 47 also studied the synthesis of LiMn 2 O 4 by the spray pyrolysis and drying system. According to their study, the X-ray diffraction analysis showed a pure crystalline material that was cubic spinel in structure, and the SEM analysis showed that the particles were spherical and in some cases, hollow.…”

Li 4 Mn 5¹x Ti x O 12 (x = 00.5) powders were successfully prepared by ultrasonic spray pyrolysis. As-prepared Li 4 Mn 5¹x Ti x O 12 powders were calcined from 500 to 700°C. The chemical and physical properties of as-prepared Li 4 Mn 5¹x Ti x O 12 powders and the calcined powders were characterized by XRD, TG-DTA, and SEM. The crystal phases of as-prepared Li 4 Mn 5¹x Ti x O 12 powders crystallized to the spinel structure (Fd-3m) by the calcination at 500°C. As-prepared Li 4 Mn 5¹x Ti x O 12 powders and the calcined powders obtained by spray pyrolysis exhibited spherical morphology with approximately 2¯m. The electrochemical measurement showed that the discharge capacity of the Li 4 Mn 5¹x Ti x O 12 (x = 0) cathodes was 111 mAh/g at the rate of 0.2 C. The discharge capacity of the Li 4 Mn 5¹x Ti x O 12 cathodes increased with the concentration of Ti ion increased. The discharge capacity of the Li 4 Mn 5¹x Ti x O 12 (x = 5) cathodes increased to 171 mAh/g (0.2 C) with increasing up to x = 5. The retention rates of the Li 4 Mn 5¹x Ti x O 12 (x = 0, 2, 3, 5) cathodes discharge capacities were approximately 84, 66, 61, and 98% after 100 cycles at the rate of 1 C, respectively.

We investigated the influence of residual acidic impurities of electrolytic manganese dioxide (EMD) and sulfate impurities of neutralized EMD on the electrochemistry of LiMn2O4 cathode. Via high temperature solid‐phase reactions, spinel lithium manganese oxide (LiMn2O4) samples were synthesized using the acidic and neutral EMD as precursor mixed with Li2CO3 for the lithium ion battery cathodes. X‐ray diffraction (XRD) pattern shows that both hexagonal and orthorhombic phases exist in EMD. Inductively coupled plasma optical emission spectrometers (ICP) and FT‐IR results show that there are sulfates impurities in EMD. SEM images show no obvious difference between EMD and four LiMn2O4 samples. The crystallinity of spinel lithium manganese (LiMn2O4) synthesized by the EMD precursor is high. The electrochemical tests show that LiMn2O4 synthesized by EMD neutralized by NH3⋅H2O (EMD−A, pH is about 7.0) precursor has the greatest discharge capacity and relatively good cycle performance among four LiMn2O4. The Raman analysis result is consistent with the electrochemical test results, as the average valence of Mn element increased of A‐LMO, cycle performance of the sample has become better. Cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) results indicate that LiMn2O4 synthesized by EMD−A precursor has better electrochemical reaction reversibility, greater peak current and smaller electrochemical resistance.
