High Sulfur Content of Mesoporous Activated Carbon Composite Derived from Water Hyacinth

Cathode composites with high sulfur content have become a concern to develop because they can improve the performance of lithium-sulfur batteries. The high sulfur content in the composite can be obtained from the carbon matrix, which has a high surface area and high electrical conductivity. Activate...

High Sulfur Content of Mesoporous Activated Carbon Composite Derived from Water Hyacinth
description Cathode composites with high sulfur content have become a concern to develop because they can improve the performance of lithium-sulfur batteries. The high sulfur content in the composite can be obtained from the carbon matrix, which has a high surface area and high electrical conductivity. Activated carbon made from biomass waste can be used as a carbon matrix due to its high surface area and ease of synthesis. In this study, activated carbon was prepared from water hyacinth (ACWH-600), which was carbonized at a temperature of 600 °C with a ZnCl<sub>2</sub> activator. Activated-carbon–sulfur composite (ACWH-600/S) was synthesized by mixing activated carbon and sulfur in a ratio of 1:3.

The high sulfur content of 58 wt%, together with the acceptable conductivity value of composite ACWH-600/S, provide an opportunity to apply these composites as cathodes in lithium-sulfur batteries.
