Electrode Manufacturing Processes TRIZ Cases

Maps seam and reference-point coordinates in merge-wound electrodes to trace defect origins and improve downstream quality analysis.

A staged charge and aging sequence stabilizes the SEI film, lowers voltage-drop variation in good cells, and sharpens low-voltage defect screening.

Laser cutting with adsorption holes and inert gas stabilizes reactive lithium film, enabling precise burr-free electrode production.

Controlling the lithium-to-anode gap at 7-15 mm improves SEI composition in roll-to-roll pre-lithiation, boosting initial efficiency and cycle life.

Separating the lithium source and electrode with a salt bridge enables pre-lithiation while limiting byproducts that damage the SEI layer.

A partially hydrolyzed structural hydrogel replaces membranes, supports ion flow, suppresses dendrites, and extends rechargeable cell life.

Pre-formed hemming shields battery cell cut edges from corrosion while supporting cap sealing, safer handling, and longer cell life.

Restraint force is increased only during the gas-generation phase of initial charging to limit gas retention without deforming the battery case.

A leveled multi-stage dispensing path applies hollow-filler resin uniformly while keeping cured reaction forces low for battery pack components.

A high-melting PVDF composition limits NMP swelling and sedimentation, enabling smoother electrode coatings with less solvent.

Oblique main lighting plus a sub-illuminator removes shadows in roll-to-roll electrode inspection, improving defect detection before lamination.

An amorphous pre-lithiated coating on cathode particles avoids irreversible lithium loss and improves lithium-ion battery cycling.

Metal nanoparticle-catalyzed CNT growth on fiber fabric preserves conductivity and load support in structural batteries for lightweight, stable energy storage.

Embedded cathode pellets and an interlocked coating reduce zinc removal force, lowering wiper breakage, friction, and power use.

Sensor-based deceleration adjusts roll supply speed as material runs low, reducing waste and unwinding damage without operator input.

An inverted laser and drum layout cuts the lower-reflectivity electrode surface to reduce debris, tab folding, and non-cutting.

Section-by-section sensing and vibration target powder agglomeration in transfer pipes, preventing clogging and stabilizing slurry production.

Variable lithium replenishing space volumes match local active material loading to prevent plating, limit capacity loss, and extend battery life.

A hydrothermally modified PPS separator adsorbs harmful species and enables uniform electrolyte distribution to extend Zn-Mn battery life.

Inclined upper knife surfaces reduce knife contact area, cutting electrode plates cleanly while minimizing dust and attached debris.

A hinged connecting rod cutter drive replaces sliding rails to prevent metal particle contamination during lithium battery electrode cutting.

Synchronized blow and suction units clear cutting debris from electrode cutters to prevent burrs, irregular cuts, and quality loss.

Pre-weakened tear lines and controlled roller tension singulate battery electrodes while reducing burrs, spikes, and separator damage.

A sealed powder feed with dry gas isolates moisture-sensitive powder during storage and transfer, preserving mixture quality without a full dry room.

Multi-point optical height sensing checks electrode sheet tabs for folding or damage, even when tab heights vary across positions.

Stepwise charging with an SEI-forming first electrolyte stabilizes the interface, cuts activation gas, and lowers cell resistance.
