At this time, multiple support arms 20 contact different positions on the bottom of the battery to be baked and avoid the bottom terminal of the battery to be baked, so that the battery to be baked and the receiving hole 10a are in a state of suspension. There is a gap between the bottom of the battery to be baked and the inner wall of the vacuum oven, and it is supported by multiple support arms 20 together, so as to support the battery to be baked while avoiding the bottom terminal of the battery to be baked, thus preventing the tray body 10 from contacting the bottom terminal of the battery to be baked, and preventing the battery baking tray from being pressured or frictionally damaged on the bottom terminal of the battery.

[0039] Please refer to the attached document. Figures 1-3 In this embodiment, the tray body 10 has a square structure and can be placed in a vacuum oven. The interior of the tray body 10 is filled with insulation material 40 to keep it warm. The tray body 10 has a receiving hole 10a that penetrates the tray body 10 and is used for inserting the battery to be baked. The receiving hole 10a can be round or rectangular to accommodate batteries of different shapes.
