“…Electrode materials are the key element in determining the rating of an energy storage device [6]. Electrode materials should be crushed and grinded to fine powder for high effectiveness of the energy storage devices [7][8][9]. A lot of development has been observed in the field of energy storage devices for improving the effectiveness and capacity of these devices [10][11][12][13][14][15][16].…”

“…Although this field of ball milling to grind electrodes is very untouched field and hence, not considered much in most of researches. Super-Capacitors can typically store 10 to 100 times more energy per unit mass than electrolytic capacitors and has much higher charge acceptance and discharge rate [9]. SCs are used in applications where there is demand for fast charge and discharge cycles like in EVs, Photovoltaic systems, Ultra-batteries, defibrillators, etc.…”

It is approximated that there will be a considerable amount of increase in worlds energy needs. So, there is a need of high energy storing devices when the load is low or moderate. Supercapacitors (SC) can be the competent options to serve this purpose. The paper recounts the performance of supercapacitors (SC) churned out from a horizontal axis multi-jar ball milling machine based on variations in material properties of ball milling jars. To store ample amount of energy, it is very essential to develop energy storing devices with large capacities and large ratings. The performance of energy storage devices is investigated using Manganese dioxide and Activated carbon as electrode materials. Majority of the times the granular size of raw-electrode materials is not enough fine to use them as electrodes directly. As a result of this, it is essential to crush the raw-electrode materials of the SC into fine powder. The energy storing capacity of SCs depends on size of particle, specific area, the of material and quantity to weight ratio of electrode material. In this paper an alternative material ‘Polypropylene’ is used as a substitute for Aluminum jars in horizontal axis multi-jar ball milling machine to crush the electrode materials. The effectiveness of both the jars is compared by evaluating the performance parameters of the SCs manufactured from electrode materials crushed in each of these jars. It is observed that the performance of SCs depends on type of ball milling machine, number of ball milling balls used, ball milling time, diameter of ball milling jars, speed of ball milling and material of ball mill jars properties. So, all other parameters are kept the same except the material of ball mill jars to scrutinize the effect of ball milling jars on performance of SCs.

“…The performance of supercapacitor mainly depends on the type of electrode material used along with process used to reduce its particle size 9,16 . Ball milling of electrode material reduces the particle size and this process is associated with many variables such as speed of ball mill machine, time of ball milling, and effectiveness in milling process 17‐19 . In the presented research work, manganese dioxide is used as metal oxide along with activated carbon as an electrode material for making electrodes of supercapacitor.…”

Type of separators along with the properties of electrode material, electrolytes decide the performance and hence the utility of supercapacitor. Nylon as a separator material is investigated in this paper. Comparison of parameters of nylon separator supercapacitor and polyethylene separator supercapacitor is presented. The processing of electrode materials plays a significant role on the performance parameters of supercapacitor. Material processing method such as ball milling is the most commonly used in energy storage devices such as supercapacitors, batteries, and fuel cells. The effect of variation of the most significant ball milling parameters such as forward‐reverse time, total ball milling time and speed of ball mill machine on the performance of supercapacitor has been studied. Modeling of ball milling process on electrode material is done by using the statistical method design of the experiment. Pulse current density is taken as new output parameters which is more important than capacitance and internal resistance. Forward‐reverse time, total ball milling time, and speed of ball mill machine are taken as input parameters for statistical modeling. Capacitance and pulse current density is taken as output parameters for the modeling of nylon separator supercapacitor. The model values of output parameters of supercapacitor are validated with experimental values.
