Ball milling is most suitable for brittle materials but not suitable for the materials that have ductility and cold welding characteristics. The mechanism in a high energy ball mill to produce fine powder is illustrated in Fig. 8.5. Also, it could be employed to oxidize the metal powder so we obtain metal oxide powders .

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 ).

Metal Oxides. Metal oxides play a very important role in many areas of chemistry, physical and materials science [1-6]. Metal oxides are formed as a consequence of co-ordination tendency of metal ions so that oxide ions form co-ordination sphere around metal ions and give rise to close packed structure.
