Primary Cell Maintainance/Servicing TRIZ Cases

A battery cooling system with a regulated evaporation valve prevents overpressure and thermal runaway when the circulation pump fails.

Elevated temperature preconditioning mitigates lithium passivation and voltage delay in Li/FeS2 cells.

Bonding composite material between anode and cathode plates increases structural strength without adding significant thickness.

A polycarbonate battery case uses vent holes and breathable filters to manage gas exhaust.

Segmented pyrometallurgical and hydrometallurgical stages isolate steel casing and convert soluble manganese into high purity MnO2 for direct electrode reuse.

Low-melting point alloys heal cracks in lithium-ion battery negative electrodes through controlled heating near their melting points.

Vacuum pressure applied through a punctured through-hole pulls pouch battery faces apart, removing gas and excess electrolyte to prevent sealing failures.

A battery protector calculates a limit coefficient based on input current to adjust vehicle component requests.

A universal battery safety assembly uses asymmetric thin metal sheets to enable selective electrical connection for diverse device requirements.

A smart power supply system dynamically allocates current to simultaneously power an application load and charge a battery using a state machine controller.

A battery management system adjusts charge thresholds based on power health metrics to maintain consistent discharge capabilities.

A control circuit executes depassivation routines to restore battery clamp voltage before device activation.

A battery detection system measures thermoelectric voltage at the contact interface to identify installed power cells.

Aqueous organic sulfonic acid separates active materials from current collectors, reducing treatment time and preventing aluminum foil dissolution.
