Embodiment 1
[0057] The invention discloses a rapid drying and cooling method for a lithium ion battery. The lithium ion battery is placed in an oven, and the heat transfer medium is an inert gas;
[0058] The heating steps are as follows: when heating, fill in inert gas for 40 minutes, keep heating for 6.5 hours, then vacuumize, and cycle accordingly;
[0059] The cooling steps are as follows: stop heating, fill with inert gas for 10 minutes, keep it for 6 hours, then evacuate, and so on.
[0060] In this embodiment, the temperature of the inert gas filled during heating is 40°C; the temperature of the inert gas filled during cooling is -20°C. The inert gas is nitrogen. The number of cycles during heating was 10 times. , the number of cycles during cooling is 5 times.
Embodiment 2
