Claims10
A method for treating at least one lithium ion battery enclosed in a housing containing aluminum, comprising:
- heating the lithium ion battery using a combustion furnace in which a combustion object is incinerated by flames, while preventing the flames from being directly applied to the housing of the lithium ion battery,
- wherein in the combustion furnace, the lithium ion battery is disposed in a battery protection container for preventing the flames from being directly applied to the housing of the lithium ion battery, and the flames are applied to an outer surface of the battery protection container, and
- wherein the battery protection container has at least one gas venting hole for discharging a gas flowing out from the inside of the housing of the lithium ion battery to the outside of the battery protection container.
