Electrode Rolling/Calendering TRIZ Cases

A secondary battery electrode uses a concave convex coating film to increase active material surface area for better component contact.

Ultrasonic vibration during calendering reduces porosity and mechanical stress in battery electrodes, improving ion transport.

A rolling roll cleaning apparatus uses an aqueous solution, air spray, heating, and a scraper to remove contaminants from electrode surfaces.

Selective heating of non-coated electrode portions minimizes elongation differences, preventing bending and ensuring uniform manufacturing precision.

Patterned binder coating prevents powder slipping during high-speed molding, ensuring uniform basis weight and low electric resistance.

A lithium ion secondary battery with a gradient electrode structure that ensures uniform charge-discharge reactions across the mixture layer thickness.

Local quality principle positions highest resistance within fifteen percent of center to suppress lithium deposition during low temperature high rate charging.

Expanded graphite withstands lithium iron phosphate expansion to preserve electric conduction paths, reducing reaction resistance at low state of charge.

A continuous manufacturing method produces non-reinforced electrochemical cell components using sequential non-solvent and pore-forming baths.

A composite lithium strip uses a removable substrate to strengthen fragile anode material, preventing breakage during electrode lamination.

Integrated metal foil anodes merge current collector and active alloying material into a single multiphase structure.
