Problems solved by technology

[0010] However, because the above-mentioned existing battery electrode drying device uses hot air or a general heater to heat the battery electrode, it is difficult to reach the target temperature in a short interval, which inevitably leads to an increase in the length of the equipment. As a result, the installation equipment takes up a lot of space, and the unit price of the products produced will rise due to the excessive heat required.
[0011] In addition, when the existing battery electrode drying device as described above is in an emergency or when the operation of the equipment is interrupted due to the failure of the equipment, the surface of the battery electrode will be subjected to thermal shock due to hot air or latent heat of the heater, thus resulting in product failure. bad question
[0012] Moreover, it is difficult to uniformly heat and dry the battery electrodes whose size has increased in a short period of time by using a general hot air heater drying method, which not only leads to a decrease in product production speed, but also has the problem of increasing the defective rate

Abstract

The present disclosure relates to a drying device for a battery electrode capable of uniformly and quickly heating and drying regardless of the size of the battery electrode by applying a radiation heating method and effectively preventing overheating and thermal shock due to latent heat.

Description

technical field [0001] The disclosure of the present invention relates to a method for drying, firing or accelerating the moisture of a film laminated on a battery electrode composed of an aluminum thin plate or a copper thin plate in the process of manufacturing a battery electrode of a battery in the form of a rechargeable secondary battery. A drying device for battery electrodes that uniformly heats battery electrodes by chemical bonding. Background technique [0002] Unless otherwise indicated in this specification, the content described in this identification item is not the prior art related to the claims of this application, even if it is recorded in this identification item, it should also be recognized as prior art . [0003] Generally, electrical and electronic devices such as mobile phones, notebook computers, digital cameras, cordless vacuum cleaners, drones, etc., inevitably include batteries in the form of secondary batteries for power supply. [0004] Recent...
