<p>PROBLEM TO BE SOLVED: To provide a system for preventing ignition/fuming of a lithium ion battery which can prevent the ignition and fuming of combustible gas as caused in the event of abnormality or the like in a lithium ion battery, and enables the increase in safety of a lithium ion battery.SOLUTION: A system for preventing ignition/fuming of a lithium ion battery comprises: a cylindrical cyclone type fine powder removing mechanism 3 serving as a fine powder removing mechanism and connected through an introduction pipe 2 to the airtight container 1 to put a lithium ion battery in; and a cylindrical gas-absorbent material-keeping container 4 located over the cyclone type fine powder removing mechanism 3, serving as a gas-retrieving part for containing a flammable spouting gas-absorbent material(not shown), and communicating to the gas-absorbent material-keeping container 4. That is, the fine powder removing mechanism is disposed for a preceding stage of the gas-absorbing part. In the system, an exhaust pipe having a reduced diameter is connected in a center portion of the upper surface of the cyclone type fine powder removing mechanism 3; and the gas-absorbent material-keeping container 4 is arranged to connect to the exhaust pipe. The gas-absorbent material is preferably LSX type, X type or A type zeolite. Especially, it is more preferable that the gas-absorbent material is impregnated with water.</p> |
