SPAN Cathode Electrode Sheet for Li-S Batteries | Custom

Name: SPAN Cathode Electrode Sheet for Li-S Batteries (Custom Single/Double-Sided)
Product Type: Sulfurized Polyacrylonitrile (SPAN) Cathode Electrode Sheet
Product Code: XN-SPAN-ES
Brand: Xnergy Materials

Product Introduction:

The SPAN Cathode Electrode Sheet is a ready-to-use, pre-coated cathode for lithium-sulfur (Li-S) battery research, built on a sulfurized polyacrylonitrile (SPAN) active material with approximately 80% SPAN content coated on aluminum foil. SPAN covalently bonds sulfur into a conductive polymer backbone, strongly suppressing the polysulfide shuttle that causes rapid capacity fade in conventional sulfur cathodes — giving researchers more stable cycling and better compatibility with carbonate electrolytes. Supplied in single- or double-sided coating with standard or custom areal loading, these electrode sheets let R&D teams skip in-house coating and move straight to coin-cell or pouch-cell assembly and electrochemical testing.

Key Features:

SPAN active material (~80% content) for stable, high-capacity lithium-sulfur cathodes
Polysulfide-shuttle suppression for longer cycle life versus conventional sulfur cathodes
Single-sided or double-sided coating to suit coin-cell and pouch-cell builds
Standard areal loading of ~4.4 mg/cm², customizable up to 6.5 mg/cm² on request
Consistent, lab-grade coating quality for reproducible comparative test data
Fully customizable active loading, dimensions, and coating configuration

Main Specifications:

Application Areas:

Lithium-sulfur (Li-S) and SPAN battery research and development
Coin-cell and pouch-cell prototyping without in-house electrode coating
Electrolyte and additive screening against a consistent baseline electrode
Benchmarking SPAN cathodes versus conventional sulfur chemistry
University, research-institute, and industrial R&D for next-generation high-energy-density batteries

Storage & Handling:

Store in a cool, dry, low-humidity environment away from direct sunlight
Keep sealed until use to avoid moisture pickup on the coating
Handle by the edges and avoid creasing or scratching the active layer
Use within the recommended voltage window for the SPAN/Li system

Specifications are provided for reference and may be adjusted to suit specific research requirements. Configuration and options are specified at order time.

Note: The SPAN Cathode Electrode Sheet gives Li-S researchers a ready-coated, reproducible cathode so testing can begin without in-house coating. Need the raw material instead? See our SPAN Cathode Powder for Li-S Batteries. Prefer a fully assembled cell? The SPAN Dry Pouch Cell pairs the same SPAN cathode with a lithium-metal anode.
