However, the heat insulating treatment using a heat insulating material is not so effective. There is a vacuum oven to insulate against heat to handle in the existing market, but its thermal-insulated vacuum layer of present vacuum oven is vacuum simultaneously with the inner chamber of placing the lithium cell, so when taking out the lithium cell, the inner chamber will lose the vacuum, and vacuum layer also can lose vacuum thermal-insulated effect at this moment, and the heat of inner chamber also can transmit away like this. The heat insulation effect is not very ideal.
