A fire suppression method and system in an aircraft involves a pressurized first-stage agent, and a pressurized second-stage agent. The first-stage agent or the second-stage agent includes trifluoromethyl iodide (CF.sub.3I). A plurality of outlets discharge the first-stage agent during a first duration and the second-stage agent during a second duration. An opening of each of the plurality of outlets is located in a lower quarter of a height of a cargo compartment.

A secondary battery includes an electrode assembly in which electrodes and separators are alternately stacked to be wound, a can configured to accommodate the electrode assembly therein, having an opening in an upper end thereof, and provided with a beading part that is bent inward to form a recessed groove, a cap assembly seated on the beading part to cover the opening of the can, an extinguishing agent accommodated in the recessed groove to extinguish ignition when the secondary battery is ignited, and a sealing part configured to seal the recessed groove.

A preparation method for a composite fire extinguishing agent with a cooling function is provided, comprising the steps of conducting refining and hydrophobic treating on heat-absorbing material; and mixing the treated heat-absorbing material and a fire extinguishing agent proportionally to obtain a composite fire extinguishing agent with a cooling function. The present invention enhances the cooling performance of the fire extinguishing agent by adding the heat-absorbing material on the basis of the existing fire extinguishing agent, wherein the heat-absorbing material can absorb the heat released by batteries through phase transition (solid-liquid) heat absorption and decomposition heat absorption.
