Aiming at the preparation of high electrochemical performance LiNi1/3Co1/3Mn1/3O2 cathode material for lithium-ion battery, LiNi1/3Co1/3Mn1/3O2 was prepared with lithium carbonate, nickel (II) oxide, cobalt (II, III) oxide, and manganese dioxide as raw materials by high-temperature ball-milling method. Influence of ball-milling temperature was investigated in this work. It was shown that the fine LiNi1/3Co1/3Mn1/3O2 powder with high electrochemical performance can be produced by the high-temperature ball-milling process, and the optimal ball-milling temperature obtained in the current study was 750°C. Its initial discharge capacity was 146.0 mAhg−1 at the rate of 0.1 C, and over 50 cycles its capacity retention rate was 90.2%.

The Li2FeSiO4cathode materialwas prepared via a solid state reaction method and subsequently heat treated at around 350°C and 700OC in Ar2atmosphere. High energy ball milling method is applied on the resulting powder with carbon additives to further modify the structure and to enhance the electrochemical performance. The structure and morphology of the prepared Li2FeSiO4powder was characterized by means of X-Ray Diffractometry (XRD) and Field-Emission Scanning Electron Microscope (FESEM). The morphological changes of the Li2FeSiO4resultedfrom different ball milling duration strongly influences the electrochemical performance of this cathode material.The Li2FeSiO4powder which was ball-milled for 48h delivered in the best electrochemical performance with a discharge capacity of 65.4 mAh/g when cycled between 1.5 and 4.8V vs. Li/Li+. Particulate morphology observed from FESEM images showed that samples that were ball-milled for 48h have reduced agglomeration compared to that ball-milled for 24h. The larger surface area for reaction with Li+improves the discharge capacity of the Li2FeSiO4cathode material.

Sintered Product

In this work, two different methods namely; dry mixing and ball milling followed by the cold isostatic press were employed to synthesize Magnesium aluminate spinel (MgAl2O4). The phase diffraction and morphological characteristic of the sintered product were analyzed using X-Ray diffraction (XRD), Scanning Electron Microscopy (SEM). The Archimedes principle for determining viscosity and porosity of MgAl2O4. The main aim of this study to compare preparation techniques on the properties of the final spinel product. The results show that the ball milling method has an advantage over the dry mixing technique. In this technique, bigger crystals, well-compacted grains, higher density, and lesser reduction size and porosity were observed. an increase in the period of milling process was found to improve all these characteristics of MgAl2O4 spinel.
