Enhanced performance of sulfur-infiltrated bimodal mesoporous carbon foam by chemical solution deposition as cathode materials for lithium sulfur batteries [PDF]

, 2019
The porous carbon matrix is widely recognized to be a promising sulfur reservoir to improve the cycle life by suppressing the polysulfide dissolution in lithium sulfur batteries (LSB). Herein, we synthesized mesocellular carbon foam (MSUF-C) with bimodal

Regulating Solvent‐Separated Ion Pairs to Control Polysulfide Redox for Fast and Stable Room‐Temperature Na‐S Batteries

Advanced Science, EarlyView.
A local high‐concentration electrolyte with tailored solvent‐separated ion pairs is pioneered to design for room‐temperature sodium‐sulfur batteries. This electrolyte allows sparingly dissolved polysulfides and localizes them onto reactive interfaces for liquid‐solid conversion.

Thin Solid Electrolyte Layers Enabled by Nanoscopic Polymer Binding [PDF]

, 2020
To achieve high-energy all-solid-state batteries (ASSBs), solid-state electrolytes (SE) must be thin, mechanically robust, and possess the ability to form low resistance interfaces with electrode materials.

Beyond the Edge: Basal‐Plane Defects as the Dominant Catalytic Sites in Sulfur‐Doped Graphene

Advanced Science, EarlyView.
Identification of basal‐plane sites in sulfur‐doped graphene challenges the conventional edge‐focused catalytic picture. Sulfur dopants together with inevitable oxygen‐containing groups modulate local charge and spin distributions, enhancing lithium binding and activating ORR/NRR intermediates.

Elemental sulfur coarsening kinetics [PDF]

, 2014
BACKGROUND: Elemental sulfur exists is a variety of forms in natural systems, from dissolved forms (noted as S8(diss) or in water as S8(aq)) to bulk elemental sulfur (most stable as α-S8).

Unveiling Copper‐Induced Phase Transitions and Degradation Mechanisms of Transition Metal Sulfide Anodes for Sodium‐Ion Batteries

Advanced Science, EarlyView.
Sodium polysulfides, which are generated from TMS anodes, react with the Cu current collector, thereby triggering Na‐Cu–S interfacial phase formation. Simultaneously, transition metals undergo ionization and redeposition on the counter electrode. The coupled processes drive the phase evolution of TMS toward the stable Cu1.8S phase.
