Batch-type apparatus and method for drying and transporting electrode plate for secondary battery

Abstract

The invention relates to a batch-type apparatus and method for drying an electrode plate for a secondary battery and transporting the dried electrode plate to a process chamber, comprising: two or more electrode plate drying apparatuses (100) for drying electrode plates loaded in a group of two or more electrode plates and discharging the dried electrode plates in a loaded state to a transport pathway (200); and the transport pathway (200) which is connected to outlet doors (D2) of the electrode plate drying apparatuses (100) and includes a conveyor (210) for transporting a plurality of electrode plates (S) loaded in a vertical direction discharged through the outlet doors (D2) to a process chamber (300), wherein the transport pathway (200) is maintained in the state of being shielded from an external space, and is formed to be directly connected to the process chamber (300) via an opening / closing door (310).

Description

technical field [0001] The invention relates to a drying and conveying device and method for polar plates used in grouped secondary batteries. Background technique [0002] In general, as the structure of electronic products such as automobiles, mobile phones, video cameras, and portable PCs becomes lighter and more functional, many studies are conducted on batteries used as power sources of electronic products and their production processes. This battery can be used continuously by charging / discharging. [0003] Generally, batteries such as nickel-cadmium batteries, nickel-metal hydride batteries, nickel-zinc batteries, and lithium secondary batteries are used as power sources of electronic products. Among them, lithium secondary batteries are widely used in consideration of life and capacity. [0004] The above-mentioned lithium secondary batteries are classified into lithium metal batteries, lithium ion batteries, and lithium polymer batteries using polymer solid electro...

AI Technical Summary

Problems solved by technology

[0011] However, the above-mentioned patent is used as a drying device to dry the plates one by one, which has low heat utilization and low drying efficiency. The drying time of each plate is correspondingly prolonged, and the plates are moved one by one, so there is a problem of consuming a large amount of energy for driving rollers and motors. question

In addition, there is no structure connected to the post-processing room, so there is a risk of contamination when moving
