Electrode Rolling/Calendering TRIZ Cases

Granulated powder deposition on collector foil with squeegee thickness adjustment and localized pressing to form active material layers.

Laser ablation removes coating films to form collector areas, resolving design freedom and production cost constraints.

Granulated active material particles press onto a current collector to form a uniform electrode layer with high adhesive strength.

An electrode applies local quality by concentrating ceramic particles in the surface part to prevent void closure and dendrite formation during overcharging.

Sequential pyrolysis in independent reactor chambers prevents silicon carbide formation and ensures homogeneous carbon shell deposition around silicon cores.

A moisture powder coating method creates high-aspect-ratio depressions in secondary battery electrodes using a two-step die pressing process.

An aluminum hydrated oxide film with phosphorus, fluorine, or sulfur additives covers the positive electrode current collector.

A porous carbon structure infused with molten lithium reduces irreversible capacity loss and suppresses dendrite growth in lithium-ion batteries.
