Cell Component Details TRIZ Cases

Strategic protrusions reinforce a large battery cell cover around the explosion-proof valve without thicker plates, lowering cost and preserving energy density.

Heat transfer parts between stacked battery cells and the case conduct heat and spread pressure to limit swelling damage and temperature rise.

Fluorescent inorganic particles bond the separator coating without excess binder, improving heat resistance, adhesion, and battery stability.

Rotatable cells with a central rotation member enable stable series or parallel battery pack layouts with greater design freedom.

Controlled silica oil absorption and agglomerate size improve separator dispersion, lowering resistivity without sacrificing puncture resistance.

Fine glass fibers below 1.6 microns are combined with strengthening fibers to raise BET surface area without high aspect ratio or weak webs.

A movable fusible link lets one fuse unit fit battery posts at different positions while keeping reliable electrical connection.

An organic-filler separator coating maintains adhesion and dimensional stability in high-temperature wet battery conditions while preserving ion pathways.

Rolled self-adhesive insulation strips replace costly prefabricated sections, simplifying battery cell housing insulation around contact elements.

Stamped protrusions reinforce a battery end cover around the explosion-proof valve hole, preserving strength, cost, and energy density.

A channeled insulation spacer guides and bends the battery tab to avoid housing contact, improving safety while removing adhesive steps.

A line-shaped laser beam with higher end intensity and tuned assist gas reduces end heat loss, avoids bead depressions, and stabilizes weld strength.

A multiple-use vent valve relieves excess cell gas pressure, then reseals for reuse and electrolyte refilling without discarding the battery.

A stepped current collector and local gap let welding gas escape, preventing blowholes and keeping battery terminal resistance stable.

Raised insulating features between battery terminals guide busbar placement and reduce short-circuit risk during cabinet assembly.

A stepped terminal joint creates gas escape space near the weld, preventing blowholes and stabilizing low-resistance battery connections.

Roll-fed PET insulation sections fit around battery contact elements, cutting housing insulation cost and handling complexity.

Segmented bus bar sections with glue injection ports improve foam filling, save pack space, and reduce short-circuit and welding risks.

A brim-mounted bracket and extender secure a hard hat headlamp without shell modification, improving retention and low-light visibility.

Varying adhesive component ratios across battery cells creates bond gradients that balance strength, elasticity, and heat conduction as modules age.

Rubber added to a microporous lead-acid battery separator helps resist contaminant-driven oxidation and extend cycle life.
