Case Study

Magnesium Oxide (MgO) Additive for Trapping Lithium Polysulfides in Lithium-Sulfur Batteries: Experimental Approach

Ponraj, R., Kannan, A. G., Ahn, J. H., & Kim, D. W. (2016). ACS applied materials & interfaces, 8(6), 4000-4006.

In this study, magnesium oxide (MgO) nanoparticles were employed as an additive to trap lithium polysulfides in the positive electrode of lithium-sulfur (Li-S) batteries, improving cycling stability and capacity retention. The experimental process involved the synthesis of sulfur-magnesium oxide (SMgO) composites, which were prepared using a ball-milling method.
The procedure began by mixing MgO nanoparticles and elemental sulfur in different ratios (95:5, 90:10, and 80:20 by weight) in ethanol. This mixture was ball-milled for 2 hours at 600 rpm to ensure uniform dispersion. After milling, the mixture was dried at 60°C overnight to remove the ethanol solvent. The resulting sulfur-MgO composites were designated as SMgO-5, SMgO-10, and SMgO-20, representing the three different MgO content ratios.
For the synthesis of lithium polysulfide (Li2S4), sulfur and 1 M lithium triethylborohydride in tetrahydrofuran (THF) were mixed in a molar ratio of 1:2.75. The mixture was heated until the sulfur dissolved, and the solution was dried under vacuum, followed by washing with toluene to remove unreacted materials. The resulting Li2S4 was dried in a vacuum oven.
To study the interaction between MgO and lithium polysulfides, 5 mg of Li2S4 was dissolved in 5 ml of THF, and 40 mg of MgO was added. After stirring for 1 hour, the solution was allowed to settle, and the precipitate was dried in a vacuum to obtain MgO-Li2S4 for subsequent characterization. All procedures were performed under an inert atmosphere in an Ar-filled glove box.
This approach highlighted the effectiveness of MgO in trapping lithium polysulfides and enhancing the performance of lithium-sulfur batteries.

Magnesium Oxide for the Preparation of Graphene Oxide Hybridized MgO Nanocomposites

Li, Meng, Shaoqi Zhou, and Mingyi Xu. Chemical Engineering Journal 328 (2017): 106-116.

Magnesium oxide (MgO) plays a crucial role in the development of nanocomposites for enhancing the performance of microbial fuel cells (MFCs). In this study, MgO nanoparticles were hybridized with graphene oxide (GO) to form a nanoflower-shaped GO/MgO composite, which was applied to the cathode carbon cloth of a single-chamber MFC. The incorporation of MgO significantly optimized the reactor's performance by improving the power generation capabilities at a low cost, a vital factor for the practical application of MFCs in environmental and energy-related technologies.
To prepare the GO/MgO composite, 0.5 g of GO was dispersed in 300 mL of deionized water and sonicated for 1 hour. Magnesium oxide nanoparticles (0.5 g) were then introduced to the solution. The mixture was subjected to centrifugation and dried at 60 °C to yield the GO/MgO composites. The use of analytical-grade chemicals ensured the high quality of the final product.
This novel approach using MgO-based composites demonstrates the potential of low-cost materials in improving the efficiency of MFCs. It also highlights the growing importance of magnesium oxide in the field of energy conversion and environmental remediation.

Magnesium Oxide for the Synthesis of MgO@N-biochar for Lead (Pb) Removal from Water

Ling, Li-Li, et al. Environmental science & technology 51.17 (2017): 10081-10089.

Magnesium oxide (MgO) nanoparticles have gained attention in environmental applications, particularly in the removal of toxic metals such as lead (Pb) from water. In this study, MgO nanoparticles were embedded in nitrogen-doped biochar (MgO@N-biochar) to enhance the adsorption capacity for Pb2+ ions, a significant environmental concern due to its harmful effects on aquatic ecosystems and human health.
The synthesis of MgO@N-biochar involved a two-stage pyrolysis process. Initially, magnesium-loaded *Typha angustifolia* biomass was subjected to fast pyrolysis at temperatures between 400-600°C, producing biochar enriched with MgO and nitrogen-containing functional groups. This was followed by isothermal carbonization to further enhance the biochar structure. The resulting MgO@N-biochar exhibited improved adsorption performance due to increased exchangeable ions and nitrogen groups, which facilitate Pb2+ uptake.
The use of MgO as a stabilizing agent in biochar significantly enhances the material's efficiency in removing Pb2+ from contaminated water, providing a sustainable and cost-effective solution for water purification. This study highlights the potential of MgO-based composites in environmental remediation, particularly in heavy metal removal, by optimizing surface interactions for enhanced adsorption efficiency.
