Silica (SiO2) is considered as a promising candidate anode material for nextgeneration lithiumion batteries (LIBs) owing to its low cost, abundant reserve on Earth, and relatively high theoretical specific capacity. However, the development of SiO2based anode materials has been impeded by their poor electrical conductivity and sluggish chargetransfer kinetics. Herein, porous SiO2/tin (SiO2 ...

The effect of ballmilling time on the mechanical properties of HDPE mesocomposites was initially studied, using mass% MCF50 silica as filler. The samples were ball milled for 1, 3, 6, and 9 h and as it can be seen, the mechanical properties of mesocomposites are improved by increasing ballmilling time (Table 1). This is because a better ...

The water can wash away the fine particles in time to avoid overgrinding. The wet ball mill has a low noise, and low environmental pollution. The wet ball mill has a simple transportation device with less auxiliary equipment, so the investment is about 5%10% lower than that of a dry ball mill. The grinding particle size is fine and uniform.
