Electrode Rolling/Calendering TRIZ Cases

Alkali metal gas reducers inside the cell chemically consume generated gases, limiting swelling while avoiding complex venting structures.

Vacuum degassing and compression form binder-free semi-solid electrodes with cleaner edges, lower electrolyte loss, and better homogeneity.

A rolled lithium nitride powder bed protects the lithium metal anode, suppressing dendrites and improving Li-S battery cycle life.

A safety layer and porous carbonized polymer film shield the current collector, limiting lithium plating and short-circuit risk in batteries.

Separate heating and pressure form an outer sealing part that evens separator adhesion, preserves wettability, and helps prevent short circuits.

Buffer members with recesses or projections improve electrode-solid electrolyte contact during roll pressing, lowering DCR resistance.

Monitoring roller roughness, electrode surface finish, and rolling load helps prevent abnormal battery electrodes without slowing production.

Alternating heating, extension, and cooling reduce uncoated-region rebound and wrinkles during electrode plate rewinding.

Low-shear mixing and calendering form a free-standing dry cathode film with minimal binder, reducing material damage and resistance.

A styrene-allyl alcohol polymer coating helps silicon-carbon anodes cut binder content while improving uniformity, processability, and cycle retention.

Direct lithium contact followed by pressure stabilization reduces silicon anode swelling, irreversible capacity loss, and cycle degradation.

A semi-dry shear-and-roll process forms porous self-supporting thick electrodes with uniform structure, strength, and scalable battery production.

An insulating carbon layer with nano-onion pores guides Li ions while suppressing dendrites, short circuits, and thermal runaway.

Multi-stage calender sheeting improves cathode thickness uniformity and strength while preserving electrolyte flow for faster charging.

A dual-layer electrode coating uses higher binder near the current collector and lower binder above it to cut DCIR while preserving adhesion and energy density.

A perforated conductive mesh lets top and bottom electrode layers touch through openings, improving conductivity and electrochemical reaction efficiency.

Filling cathode pores with sacrificial salt pre-lithiates silicon anodes, preserving capacity and life while lowering short-circuit risk.

Soft carbon coated on artificial graphite limits pore-volume change during electrode rolling, improving high-temperature storage and rapid charging.

Pre-pressing and a 32.5%+ stress relaxation rate suppress end cracking in lithium-titanium oxide negative electrodes during roll-pressing.

Controlling soft carbon coating on artificial graphite limits pore-volume change during rolling, improving high-temperature storage in lithium secondary batteries.

Inclined or stepped layer edges and an auxiliary roll prevent low-density transition zones during roll pressing of battery laminates.

Electrode buffer layers in a sulfide-based solid-state battery limit porosity from volume changes while preserving adhesion and conductivity.

PVD coating builds thin solid-state electrolyte layers with better electrode contact, improving ion mobility, stability, and dendrite resistance.

Sensors and feeder hoppers keep dry electrode powder delivery consistent, enabling uniform calendered thickness without solvent-based coating.

Integrated electric heating, sensors, and zoned control keep roller temperature uniform to limit thermal expansion and film thickness variation.
