Solvent-Free Dry Cathode
Overview
NAMI has developed a dry process for the fabrication of lithium ion battery cathodes.
Commercialisation opportunities
Non-exclusive licensing
Problem addressed
Unlike the conventional slurry cathode which uses harmful solvents in the fabrication process, NAMI’s dry process is much safer, low-cost and more environmentally friendly without using harmful solvents for cathode and battery fabrication.
Innovation
- NAMI’s dry process is ideal for high capacity loading cathodes of 5 mAh/cm² and above.
- As a dry process, there is no limitation on the binder variety used in the cathode, enabling easy material optimization for the resultant electrode properties including high stability, high power and high flexibility.
Key impact
- Easy fabrication
- High capacity loading
- High variety of binder for different electrode properties
- Environmentally friendly and low manufacturing cost
Application
- Any lithium ion batteries including electric vehicle batteries, consumer electronic batteries, energy storage batteries, and special application batteries, etc.
