Copious forms of energy are available in nature, but electrical energy is the convenient form of energy. As a result of this, it is expected that the need for electrical energy will increase considerably by the end of this decade. Thus, the storage of electrical energy is now becoming of paramount importance. Nevertheless, ultra-capacitors are currently a central area of research for energy storage devices due to their high-power density rating, short charging time and long cycling time. The capacitance of an ultra-capacitor is majorly a result of the processing of its electrode materials. Ball milling is one of the most profitable and cost-effective processes of electrode material processing. However, in most of the ball milling research, the focal point is on materials used for balls in ball milling. It is also observed that the material used to produce ball mill jars is of equal momentousness. So, this research aims to examine various materials as jars for a ball milling machine.
