Secondary Cells TRIZ Cases

A two-layer negative electrode controls tortuosity to preserve conductive paths, enabling fast charging and better cycle life with silicon.

Open cell accommodation portions vent gases and flames outside the module to limit thermal propagation and prevent adjacent cell ignition.

A PID-triggered CNN-LSTM virtual sensor infers full battery temperature fields from limited measurements to improve thermal monitoring accuracy.

An ester-containing silicone thermal composition keeps low viscosity for gap filling while maintaining heat resistance and limiting siloxane byproducts.

Thermally expanding vent seals keep battery housings ventilated in normal use, then block airflow to suppress fire spread and re-ignition.

Cell tubes, insulating spacers, and an exhaust channel limit heat transfer and fire spread between aircraft battery cells.

A Li-rich fluorinated cathode oxide with Al and added elements suppresses metal elution while preserving high capacity and cycle endurance.

A Si-C/Si-O polymer coating and tuned electrolyte stabilize the carbon anode interface, reducing defects and improving cycle and high-temperature storage.

A recessed separator area relieves swelling load at the can-sealing joint, improving power storage module reliability without heavier restraints.

Carbon fiber separation sheets channel heat along the casing to cool pouch cells and limit heat transfer to adjacent packs in eVTOL batteries.

Calcium between aggregated cathode primary particles suppresses oxygen release, preserving layered structure and improving battery life.
