Secondary Cells TRIZ Cases

A polymer with amide or imide bonds lowers electrode-forming liquid viscosity for stable piezo discharge, strong adhesion, and lower resistance.

A foam-and-spacer multilayer structure insulates battery cells, resists compression, and accommodates cell expansion to limit thermal runaway spread.

Direct-contact housing and heat sink integration improves battery cell heat removal, cooling uniformity, space use, and assembly efficiency.

A spacer plate and mounting wall replace beams and side plates to raise battery pack space utilization, strength, and energy density.

An outward-protruding cooling plate section moves coolant inlet and outlet joints outside the case to block leakage into battery cells.

Thermal runaway gases are routed through a cooling-plate channel and longer venting path to lower exit temperature and reduce burn and fire risk.

Different-diameter bolting members compress battery cells through the cover plates, simplifying module assembly and disassembly while controlling swelling.

A nitrogen-containing binder and controlled electrode porosity suppress swelling and side reactions, preserving Li-ion output and cycle life at high temperature.

A low-melting fluorine-based binder and intermediate layer curb gas generation, swelling, and electrode detachment in batteries.

Cooling material applied directly to pouch-cell tabs removes heat from the jelly roll, cutting thermal gradients and pack cooling weight.

A wide-contact lifting support with local reinforcement keeps the battery module end plate thin while maintaining lifting rigidity and cell space.

Combining a cyano ester compound with a cyclic sulfuric acid ester stabilizes non-aqueous battery electrolytes against storage capacity loss and cycle fade.

A battery pack with a wireless receiver, power IC, and I2C microcontroller adds wireless charging to legacy devices without redesign.

An offset mounting-hole layout with ribs and cavities helps the end plate resist battery expansion, limiting deformation and improving assembly stability.

A trinitrile, cyclic carbonate, and high linear carbonate electrolyte cuts impedance growth, improves coulombic efficiency, and suppresses gas generation.

A tackified, photocured acrylic sheet balances high filler loading with strong adhesion and heat dissipation for battery modules.

Intersecting electrode lead and tab directions cut coupling and sealing space in a pouch battery, improving size-to-capacity efficiency.

Fine carbon black and small-diameter carbon nanotubes build conductive paths in LFP electrodes without sacrificing active material content or cycle life.
