Problems solved by technology
Conventional glove boxes have two configurations in the production of lithium-ion batteries. One is that the cell oven is placed outside. After the cells are dried in the oven, they are transferred into the glove box through the vacuum transition chamber of the glove box. The disadvantage is that the transfer needs to be exposed. Air and batteries have secondary pollution; the second way is that the oven is directly connected to the glove box, but the drying time of the batteries is very long, which limits the output requirements for continuous production

Embodiment Construction
[0013] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0014] like figure 1 Shown is a schematic diagram of the principle of the present invention. like figure 1 As shown in the schematic diagram, batches of batteries are stacked and loaded into a movable oven. After drying, the oven is moved to the vicinity of the glove box, and the oven is connected to the connection transition chamber of the glove box. After the transition chamber is cleaned, the transition chamber is opened. cabin and oven door, transfer the cells into the glove box, and close the open transition cabin and oven door, remove the oven and reload the cells for drying, and at the same time, transfer the connection between the new oven and the glove box The cabins are connected, and such a cycle operation realizes continuous batch battery production.

The invention discloses a method and a device for continuously drying a battery core of a lithium battery and injecting electrolyte, which can both realize continuous production and improve the production capacity. The method comprises the following steps of: drying the battery core by using a drying oven, namely simultaneously drying the battery core of the lithium battery by using at least two drying ovens or drying the battery core at intervals and transferring the battery core dried by one drying oven into a glove box in a pollution-free way by using a butting device for injecting the electrolyte; injecting the electrolyte by using the glove box, namely sequentially transferring the battery cores dried by other drying ovens into the glove box by using the butting device for injecting the electrolyte; and performing cyclic operation according to the steps.
Description
technical field [0001] The invention relates to a new process device in the production process of lithium-ion batteries. After the battery cells are dried, they are quickly transferred to the glove box without pollution, and the battery liquid injection is completed in the glove box. In particular, it relates to a device A method and device for continuously realizing lithium battery cell drying and liquid injection. Background technique [0002] In the current field of lithium-ion battery production, especially in the field of lithium-ion power batteries, the batteries need a long drying process before being injected with electrolyte, and then enter the drying room to complete the quantitative injection of electrolyte. After drying, it enters the drying room to inject liquid, which can realize large-scale continuous production, but there are three disadvantages. First, the construction cost of the drying room is high, and the power consumption is large during continuous oper...
