Secondary Cells TRIZ Cases
- Corrugated Energy Storage Housing for Passive Heat Dissipation
Corrugated thermally conductive side walls increase housing surface area to dissipate cell heat without added cooling fins or plates.
- Battery Module Cold Plate Cut-Outs for Compact Multi-Module Cooling
Cold plate cut-outs house side-plate edges to improve cell cooling, save space, and simplify assembly across multiple battery modules.
- Cold Plate Flow Channel Layout for Uniform Cooling and Low Pressure Drop
Parallel jets and orifice-guided flow paths spread coolant evenly across the cold plate while lowering pressure drop and pump power.
- α-Alumina Slurry for Smoother Battery Separator Porous Membranes
Controlling α-alumina crystallite size and lattice strain suppresses coarse aggregates, smoothing separator membranes to prevent punctures and shorts.
- Battery Pack Cell-to-PCB Adhesive Structure for Stable Sensing
A stepped UV-curable adhesive structure secures cell ends, holder, and PCB to prevent sensing disconnections and improve heat dissipation.
- Staggered Battery Module Layout for Heat and Expansion Control
Offset rows of different-length battery cells improve rigidity, heat dissipation, and temperature uniformity while reducing expansion stress.
- Power Module Microchannel Substrate for Compact Heat Dissipation
Crisscrossed substrate microchannels improve coolant circulation in EV power modules, boosting heat removal while reducing size and assembly complexity.
- Coated Non-Woven Battery Separator for High-Temperature Stability
A non-woven separator with ceramic particles and a high-melting binder improves heat resistance, coating adhesion, and dendrite suppression in Li-ion cells.
- Battery Pack Spray Pipeline for Cell-Level Thermal Runaway Cooling
A spray pipeline opens at a cell fragile portion during thermal runaway, directing coolant into the affected cell to limit spread and short circuits.
- Battery Module Air-Duct Separator for Uniform Cell Cooling
A middle separator with multi-direction air ducts cools stacked cell layers more evenly, reducing thermal gradients and extending battery module life.
- Iodine-Boron Cathode Coating for Low-Resistance Li-Ion Batteries
An iodine-boron coating on lithium transition metal oxide helps nickel-rich cathodes retain capacity while limiting electrode resistance growth.
- Battery Self-Heating Control Using Temperature and State of Charge
Closed-loop battery self-heating adjusts current amplitude and frequency by temperature and state of charge to improve low-temperature charging.
- Aircraft Battery Cell Layout for Uniform Heat Conduction
Opposed cell orientation and overlapping battery sets spread heat more evenly, enabling smaller aircraft cooling hardware and lower power use.
- Elastic Tab Limiting Sheet for Battery Tab Short-Circuit Prevention
An elastic tab limiting sheet absorbs tab deformation, prevents reversal and contact, and keeps battery tabs safely separated.
- Lithium-Ion Cathode Material with Controlled Crystallite Boundaries
Controlled crystallite boundaries in Ni-rich lithium-ion cathodes improve lithium diffusion while preserving structural integrity and cycle life.
