Enhancing Performance of Li4Ti5O12 with Addition of Activated Carbon from Recycled PET Waste as Anode Battery Additives

Abstract

The rapid development of the industry makes the amount of plastic waste increase. The difficulty of plastic waste to be degraded makes its handling important to avoid environmental pollution. This research converts plastic waste into activated carbon with to increase the economic value by apply the activated carbon as an anode battery additive. Li4Ti5O12 has advantages as a lithium ion battery such as a good level of safety and thermal stability but poor conductivity. The recycled carbon is activated using NaOH to obtain a porous structure that can increase the conductivity of the LTO/C composite. The activated carbon itself has conductivity of 9,65.10-5 S/m. The effect of activated carbon to the overall battery performance was being studied in this research. This study synthesized LTO/C using the ball-milling method with variations of 90 minutes, 120 minutes, and 150 minutes milling to determine the optimum composite synthesis time for the battery. The EIS test showed that the addition of activated carbon was able to increase the LTO conductivity. Based on the results of EIS, CV and CD the optimal ball mill time is 90 minutes to produce a battery with the best performance and has the lowest resistance and a specific capacity of 149,8 Ω.

Preparation and Characterization of Pelleted and Powdered Activated Carbons Derived from Used Brewed Coffee

“…Activated carbon has a large specific surface area, a diversified pore size distribution, and a range of functional groups due to the irregularity of the nanopores structure [1]. As a result, it has a high adsorption capacity and can adsorb molecules of various substances and dimensions, allowing it to be used in a variety of applications such as CO2 adsorption [2][3][4], biogas purification [5,6], supercapacitor [7,8], electrode battery [9,10], methylene blue adsorption [11,12], methane storage [13,14], water vapor adsorption [15,16], air conditioning applications [17], carbon nanotube [18][19][20], etc.…”

Effect of Calcination Temperature on The Properties of Eggshell Waste (EW) Powder for Biomedical Application

“…Thus, exploration through research in materials science, especially in the field of waste material, has become a serious issue and has led the researcher to the point that waste from daily domestic use and the food processing industry can be transformed and converted into some helpful product and yet seems to be achievable 4) . In the same context, eggshells are generally known as one of the most significant contributors to agricultural waste, capable of constituting environmental problems and pollution as it contributes to 250,000 tons annually worldwide in dumping areas 5),6), 7) . The efficacy of converting eggshells to productive use becomes worth adopting in the ever-increasing initiatives to convert waste into a high-value product.…”
