Lithium-Ion Cathode Electrode Sheets

Lithium-ion cathode electrode sheets are pre-coated positive electrode sheets for lithium-ion battery research, materials screening, and electrochemical testing. They are suitable for coin half-cells, lithium-ion full cells, pouch cell prototypes, and solid-state or semi-solid lithium-ion cathode studies. Standardized electrode sheets help reduce variables from slurry preparation, coating, and drying, allowing experiments to focus on cathode chemistry, areal loading, coating structure, and cell assembly conditions.

This category covers common lithium-ion cathode systems, including LFP, LCO, NCM/NMC, NCM811, high-nickel NCM, Ni90, and LMR pre-coated cathode electrode sheets. Available formats may include single-sided coating, double-sided coating, wet-process coating, dry-process cathode fabrication, aluminum foil or carbon-coated aluminum foil current collectors, and small-pack formats for laboratory R&D.

When selecting lithium-ion cathode electrode sheets, key factors include cathode material system, coating areal density, active material ratio, coated area, coating side, compaction density, current collector type, baking requirements, and storage conditions.

Custom Lithium-Ion Cathode Electrode Sheets

When standard specifications do not meet a specific experimental design, loading target, or cell structure requirement, custom lithium-ion cathode electrode sheets can be requested. This customization direction is limited to lithium-ion battery cathode systems and is suitable for pre-coated cathode electrode sheets based on LFP, LCO, NCM/NMC, NCM811, high-nickel NCM, Ni90, LMR, and other lithium-ion cathode materials.

Customizable items may include cathode material system, active material ratio, conductive additive and binder system, coating areal density, target areal capacity, coated area, single-sided or double-sided coating, aluminum foil or carbon-coated aluminum foil current collector, compaction density, sheet dimensions, reserved tab area, cutting method, vacuum packaging, and dry storage requirements.

Custom Parameter Recommended Details to Provide
Cathode Material System LFP, LCO, NCM/NMC, NCM811, high-nickel NCM, Ni90, LMR, or customer-specified lithium-ion cathode material
Coating Process Wet coating, dry-process cathode fabrication, or special binder system
Target Loading Areal density in mg/cm², areal capacity in mAh/cm², or target active material mass
Coating Structure Single-sided or double-sided coating, coating width, uncoated margin, reserved tab area design
Current Collector Aluminum foil, carbon-coated aluminum foil, specified thickness, or special surface treatment
Applicable Testing Coin half-cell, lithium-ion full cell, pouch cell, or solid-state/semi-solid lithium-ion cathode testing
Post-Treatment Requirements Compaction density, baking conditions, cutting size, vacuum packaging, or dry storage
Quantity and Delivery Sample quantity, batch requirements, and whether repeat-batch consistency is required

Frequently Asked Questions

What is the difference between single-sided and double-sided lithium-ion cathode electrode sheets?

Single-sided cathode sheets are suitable for half-cell testing, coin cells, and material screening. Double-sided cathode sheets are closer to full-cell or pouch cell structures, but require more careful capacity matching, separator selection, and assembly control.

How should I choose between LFP, NCM/NMC, LCO, Ni90, and LMR cathode sheets?

Choose LFP for stable baseline research, NCM/NMC for high-energy lithium-ion evaluation, LCO for lithium cobalt oxide or high-voltage cathode studies, Ni90 for high-nickel cathode testing, and LMR for next-generation high-capacity cathode research.

Are dry-process lithium-ion cathode sheets better than wet-process cathode sheets?

They are suited to different research directions. Dry-process cathode sheets can support solvent-free, high-loading, and solid-state or semi-solid lithium-ion battery research, while wet-process cathode sheets are widely used for conventional lithium-ion electrode benchmarking.

Can these lithium-ion cathode sheets be used directly in coin cells?

Most cathode sheets can be cut or punched for coin cell assembly, but users should confirm the coating side, electrode diameter, active material mass, drying requirements, and whether glovebox assembly is needed.

Can coating density or sheet dimensions be customized?

Yes. For projects requiring non-standard loading, coated area, current collector, single-sided or double-sided coating, or dry-process cathode fabrication, custom lithium-ion cathode electrode sheets can be requested.

What parameters are needed for custom lithium-ion cathode electrode sheets?

Recommended information includes cathode material system, target areal loading or areal capacity, coated area, sheet dimensions, single-sided or double-sided coating, current collector type, intended cell type, and estimated quantity. For high-nickel cathodes, LMR, high-loading cathodes, or solid-state/semi-solid lithium-ion battery research, target compaction density, interface requirements, storage conditions, and post-treatment requirements are also helpful.
