Research Project: SDC Polymer Architectures for Lithium\u2013Sulfur Batteries<\/strong><\/p>\n

Our research focuses on developing Soft Dendritic Colloid (SDC)-engineered polymer architectures for application as functional interlayers and integrated cathodes in lithium\u2013sulfur (Li\u2013S) batteries. This project aims to enable high-energy-density, long-cycle-life Li\u2013S systems suitable for electric vehicles and large-scale energy storage. Despite their high theoretical energy density, Li\u2013S batteries face several critical challenges: (i) the dissolution and shuttling of lithium polysulfides (LiPSs), which leads to rapid capacity fading and low Coulombic efficiency; (ii) the intrinsic insulating nature of sulfur and its discharge products, resulting in sluggish redox kinetics; (iii) significant volume expansion during cycling, which compromises structural stability and long-term durability.<\/p>\n

Our SDC polymer platform addresses these limitations through the fabrication of a dendritic, high-surface-area fibrous network derived from poly(vinylidene fluoride) (PVDF). The shear-driven phase separation process produces a three-dimensional, interconnected \u201cfish-net\u201d morphology that can be integrated with conductive nanomaterials such as carbon nanotubes (CNTs), graphene, or MXenes.As a functional interlayer, the SDC structure acts as a conductive and catalytic barrier that physically confines polysulfides, accelerates LiPS conversion, and reduces charge-transfer resistance while maintaining efficient lithium-ion transport. When applied directly within the cathode, the same architecture provides a robust conductive scaffold that improves sulfur immobilization, enhances electrochemical utilization, and accommodates volumetric expansion during cycling.<\/p>\n

Through this project, we aim to advance the practical implementation of Li\u2013S batteries by combining materials engineering, interfacial design, and scalable fabrication strategies. The SDC polymer architecture provides a multifunctional and adaptable platform that moves Li\u2013S technology closer to commercial viability while supporting the growing demand for sustainable, high-energy storage systems.<\/p>\n","protected":false},"excerpt":{"rendered":"
