Electrode Manufacturing Processes TRIZ Cases

Multilayer electrode films use radiation-cured binders and tailored layer compositions to raise energy density without sacrificing power or durability.

Corrugating battery electrodes improves active material stripping while limiting deformation, impurity mixing, and high-temperature recycling steps.

Laser notching separates normal and defective electrode portions inline, avoiding stoppages and mold changes in secondary battery production.

Opposed upper and lower cutters move at the same speed to cut electrode sheets cleanly, reducing deformation and residue for stable stacking.

Liquid-phase deposition forms artificial SEI coatings that improve Li-Ion electrode thermal stability without slowing high-volume manufacturing.

A Na or Al first coating plus a boron heat-formed second layer improves cathode surface stability and high-temperature battery life.

Region-specific lithium pre-doping at the negative electrode end suppresses edge precipitation while preserving cycle durability and energy density.

Automated tape adhesion and optical measurement quantify electrode active material peeling, reducing human error and improving test consistency.

Location-based data mapping links battery manufacturing and inspection records to trace curvature defects and improve prediction accuracy.

Controlled cohesion strength and vertical resistance help silicon negative electrodes limit expansion damage and capacity fade in lithium secondary batteries.

Two laser heads combine notching and singularizing in one continuous pass to cut electrode films with less wear, downtime, and machine complexity.

Movable non-contact temperature sensing and individually controlled fans reduce battery temperature deviation during formation and capacity testing.

Laser transmitters and receivers detect transfer line clogging in dry electrode material flow and pinpoint the blocked section for partial replacement.

A PVDF and perfluorinated olefin copolymer binder enables lithium-ion positive electrodes to be made at low temperature with greener solvents.

Modular shuttle tracks let battery cell formation plants expand capacity through fast layout changes while keeping precise tray insertion at chambers.

High-frequency sonotrode cutting separates alkali metal foils without sticking, reducing contamination, cleaning downtime, and fire risk.

Seam and reference-point detection reconstructs merge-wound electrode coordinates on a roll map for defect tracing and quality tracking.

A copolymer-coated porous carbon sulfur composite catalyzes polysulfide reduction, cuts overvoltage, and extends lithium secondary battery life.

Controlling Si charge and discharge depth with pre-lithiation helps silicon-anode cells limit expansion damage while keeping high capacity and fast charging.

Real-time pressure sensing and platform angle adjustment improve layer adhesion in unfinished battery cells by keeping pressure uniform.

A movable cutter shifts between good and defect cut positions so faulty electrodes are recovered separately and do not enter cell assembly.

Measures electrode peeling force after electrolyte immersion, giving adhesion data that reflects real wet battery conditions.

Dual heat-dissipation members cool pulp in both mixing and dispersing cavities, enabling high-speed stirring without heat-induced activity failure.

Pressure-based air flow control keeps battery slurry moving through a clogging filter, protecting slurry quality and extending filter life.

Voids formed in a tin-carbon anode buffer expansion during charging, improving cycle life and limiting initial battery swelling.

A crosslinked separator coating bonds with the anode binder to prevent delamination and coating cracks in silicon-based secondary batteries.

Controlling eutectic magnesium anode crystal orientation promotes uniform deposition, cutting overvoltage and internal short circuits.
