The Scientific Problems Behind Better Batteries
Sulfur and sodium chemistries fail for reasons that are chemical, structural and kinetic at once. Each problem below connects to a material or cell-level response investigated in this work.
Scientific challenge
Polysulfide shuttling
Soluble intermediates formed at the cathode migrate across the separator, react at the metal anode and are lost to the working reaction.
Material and cell-level response
Polar adsorption→
Functional separator→
Catalytic conversion→
Improved active-material retention

Selected Research Contributions
Four research outputs, each stated with its challenge, material architecture, mechanism and verified result. Publication status is recorded exactly as it stands.
01Published
Orange-Peel-Derived Hierarchical Porous Carbon
Challenge
Sulfur is electronically insulating and its intermediate species dissolve into the electrolyte during cycling.
Material architecture
A hierarchical porous carbon derived from orange peel was used as a sulfur host, providing a conductive framework with an ion-accessible pore network.
Mechanism
Physical confinement of sulfur inside a hierarchical pore structure, with the carbon framework supplying the electronic pathway the sulfur lacks.
Verified result
Initial discharge capacity of 870 mAh g⁻¹ at 0.2 C, retaining approximately 57% of capacity after 200 cycles.
Soluble lithium polysulfides diffuse away from the cathode and across the separator, removing active material from the reaction.
Material architecture
Polar TiO₂ phases were grafted onto a conductive carbon sheet and placed between cathode and separator as a functional interlayer.
Mechanism
Chemical interaction between the polar oxide and polysulfide species, combined with a conductive sheet that keeps intercepted material electrochemically accessible.
