Core 700 can be any form, for example, it may be in the naked battery core 700, rectangular lithium ion battery in column lithium ion battery
Naked battery core 700, the naked battery core 700 in button lithium ion battery or the naked battery core 700 in film lithium ion battery etc., to this
With no restriction.
Specifically, the temperature of vacuum oven 200 is set as between 80 DEG C~90 DEG C, specifically can be 85 DEG C, thus vacuum
Temperature in oven 200 can maintain between 80 DEG C~90 DEG C.Naked battery core 700 the setting at a temperature of toast, such as 20min
~30min;Then vacuum oven 200 is vacuumized, until the air pressure in vacuum oven 200 is in 0.05MPa hereinafter, continuing to toast
20min~30min;It is then charged with high pure nitrogen, continues to toast;It is aforementioned vacuumize and repeated the step of being filled with high pure nitrogen into
Row repeatedly, finally obtains the moisture content of naked battery core 700 in 400ppm hereinafter, moisture is qualified.The temperature of naked battery core 700 is logical at this time
