Engineering the morphology/porosity of oxygen-doped carbon for sulfur host as lithium-sulfur batteries

Limin Zhang et al.

Summary: This study designed carbon materials with rational morphology and pore structures to enhance the loading and adsorption capacity of sulfur, thereby improving the energy storage performance of lithium-sulfur batteries. Through rational design, variations in sulfur immobilization were successfully achieved, leading to increased cycling stability. The results show that mesopores in carbon exhibit more fascinating traits in improving sulfur utilization and suppressing Li2Sx formation, ultimately enhancing ion storage capacity in Li-S batteries.

In Situ Localized Polysulfide Injector for the Activation of Bulk Lithium Sulfide

Matthew Li et al.

Summary: Activation of commercial Li2S is a key challenge in commercializing sulfur-based Li-ion battery systems. This study uses commercial Na2S as a polysulfide injector to activate commercial Li2S, allowing for activation at lower voltages and with lower electrolyte content. Compared to pre-solvated redox mediators, this technique offers a simpler and more efficient way to activate commercial Li2S.

Expediting the Conversion of Li2S2 to Li2S Enables High-Performance Li-S Batteries

Zhanshuang Jin et al.

Summary: The conversion of Li2S2 to Li2S is a crucial step in lithium-sulfur (Li-S) batteries, and the catalysts in these batteries are often ineffective due to poor contact with solid Li2S2. By designing pomegranate-like sulfur nanoclusters@nitrogen-doped carbon@nitrogen-doped carbon nanospheres (S@N-C@N-C NSs), the rapid conversion of ultrafine Li2S2 to Li2S can be achieved. The cathodes with this nanostructure exhibit excellent sulfur utilization, high rate performance, and low capacity decay rate, showing potential for energy storage applications.
