Descripción general

Especificaciones

SPAN (Sulfurized Polyacrylonitrile) is a sulfur-based cathode material designed for lithium–sulfur (Li–S) battery research. It is typically supplied as a black powder and features sulfur chemically integrated with a polyacrylonitrile-derived matrix.

This structure helps immobilize active sulfur species and suppress the dissolution and migration of soluble polysulfides during charge and discharge, thereby reducing the polysulfide shuttle effect commonly associated with conventional sulfur cathodes. SPAN can also provide improved structural stability and cycling performance.

It is suitable for lithium–sulfur battery cathode research, electrochemical performance evaluation, material screening, and the development of next-generation high-energy-density battery systems.

Key Advantages

Suppressed Polysulfide Shuttle Effect
The SPAN structure helps immobilize sulfur species and reduce polysulfide dissolution and migration during cycling.

Improved Cycling Stability
The polymer-derived framework helps maintain structural stability during repeated charge and discharge.

Suitable for Cathode Formulation Development
SPAN can be used as an active cathode material for slurry formulation, electrode fabrication, and cell-level electrochemical evaluation.

Designed for Battery R&D
Suitable for academic research, material screening, formulation optimization, and lithium–sulfur battery development.

Compatible with Multiple Cell Formats
Can be used for the preparation and evaluation of cathodes for coin cells, pouch cells, and other laboratory-scale lithium–sulfur battery systems.

Applications

SPAN is suitable for:

Lithium–Sulfur Battery Research
Sulfur Cathode Development
Cathode Slurry Preparation
Electrode Fabrication
Material Screening and Evaluation
Electrochemical Performance Testing
Coin Cell and Pouch Cell Research
High-Energy-Density Battery Development

Recommended Use

SPAN can be incorporated into cathode formulations with appropriate conductive additives and binders according to the specific research system and experimental requirements.

Electrode formulation, areal loading, coating thickness, calendering conditions, electrolyte system, and cell configuration should be optimized according to the target lithium–sulfur battery system and testing objectives.

Storage and Handling

Store the material in a dry, sealed environment and avoid prolonged exposure to moisture or contaminants. Appropriate handling procedures should be followed during weighing, slurry preparation, electrode fabrication, and cell assembly to maintain material consistency and experimental reproducibility.
