Abstract

The invention provides a drying device of a battery pole shoe. The drying device comprises a drying box body, a vacuum-pumping unit and a heating unit, wherein the heating unit is arranged on the drying box body; the vacuum-pumping unit is connected with a drying box; a drying agent which is used for drying a battery is arranged in the drying box; and the drying agent is arranged at one side of the battery pole shoe. After the technical scheme is adopted, the drying agent is arranged in the battery drying device and can effectively absorb and dry water vapor generated by the battery pole shoe; therefore, when the battery pole shoe is dried, nitrogen is not needed to be injected into the battery driving device at intervals, thereby the drying efficiency is obviously improved, and the drying cost is effectively reduced. The invention also provides a drying method of the battery pole shoe.

Description

technical field [0001] The invention belongs to a drying device for battery pole pieces, in particular to a drying device for lithium ion batteries. [0002] The invention also relates to a method for drying battery pole pieces. Background technique [0003] Battery pole pieces are an indispensable part in the manufacture of lithium-ion batteries. In the process of manufacturing battery pole pieces, it is necessary to dry the battery pole pieces so that the water content of the battery pole pieces meets the process requirements. The battery pole piece will produce water vapor during the drying process, and a large amount of water vapor gathers in the battery pole piece drying device, which is not conducive to the drying process of the battery pole piece. [0004] In order to solve this problem, the existing battery pole piece drying equipment is equipped with a nitrogen gas inlet. During the battery pole piece drying process, nitrogen gas is injected into the battery dryin...
