Abstract
Official abstract text for this publication.
The present invention provides 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.
First claim
Opening claim text (preview).
What is claimed is: 1 . 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. 2 . The method for treating the lithium ion battery according to claim 1 , wherein a temperature of the lithium ion battery in the combustion furnace is increased in an air atmosphere. 3 . The method for treating the lithium ion battery according to claim 1 , 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. 4 . The method for treating the lithium ion battery according to claim 3 , 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. 5 . The method for treating the lithium ion battery according to claim 3 , wherein in the battery protection container, a filling material is arranged together with the lithium ion battery. 6 . The method for treating the lithium ion battery according to claim 5 , wherein the filling material is in the form of powder. 7 . The method for treating the lithium ion battery according to claim 6 , wherein the powder is alumina powder. 8 . The method for treating the lithium ion battery according to claim 5 , wherein in the battery protection container, the entire lithium ion battery is embedded in the filling material. 9 . The method for treating the lithium ion battery according to claim 1 , wherein after heating the lithium ion battery, the lithium ion battery maintains the state where the lithium ion battery is enclosed in the housing. 10 . The method for treating the lithium ion battery according to claim 2 , 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. 11 . The method for treating the lithium ion battery according to claim 4 , wherein in the battery protection container, a filling material is arranged together with the lithium ion battery. 12 . The method for treating the lithium ion battery according to claim 6 , wherein in the battery protection container, the entire lithium ion battery is embedded in the filling material. 13 . The method for treating the lithium ion battery according to claim 7 , wherein in the battery protection container, the entire lithium ion battery is embedded in the filling material. 14 . The method for treating the lithium ion battery according to claim 2 , wherein after heating the lithium ion battery, the lithium ion battery maintains the state where the lithium ion battery is enclosed in the housing.
