Among them, high-energy ball-milling is widely used in large-scale preparation of metal oxide composites for lithium-ion batteries (LIBs). However, ball-milling-induced high-energy mechanical activation may destroy crystalline structure, and thus the electrochemical activity of many metastable oxides such as anatase titanium dioxide (TiO 2 ).
High-energy ball milling is a mechanical deformation process that is frequently used for producing nanocrystalline metals or alloys in powder form. This technique belongs to the comminution or attrition approach introduced in Chapter 1.
Nanoparticles of zinc oxide (ZnO) are increasingly recognized for their utility in biological applications. In this study, the high-energy ball milling (HEBM) technique was used to produce nanoparticles of ZnO from its microcrystalline powder. Four samples were ball milled for 2, 10, 20, and 50 hours, respectively.
A high energy ball milling (HEBM) technique has successfully been used to synthesis nanocrystalline ferroelectrics and other alloys [3, 4]. Though nanocrystalline ceramics can be synthesised by a range of different physical, chemical, and mechanical methods, HEBM offers several advantages over the other methods [5–7].
