Publication number: 20230114069Abstract: Disclosed is a method for manufacturing a dry electrode. The method includes buffing the surface of a pre-electrode film formed in a sheet-like shape to remove the surface waviness in the manufacture of an electrode film, and then carrying out a calendering process, thereby ensuring the uniformity of the electrode film thickness and electrode active material density in the electrode film. In other words, it is possible to minimize a deviation in loading amount, porosity and thickness of the electrode depending on the location, and thus to provide improved overall electrochemical performance, including improved battery life characteristics.Type: ApplicationFiled: September 30, 2022Publication date: April 13, 2023Applicant: LG Energy Solution, Ltd.Inventors: Dong-Mok Shin, Sang-Min Kwak, Dong-Oh Shin, Kwang-Ho Yoo

Publication number: 20230042207Abstract: Disclosed is a method for manufacturing a dry electrode. The method allows determination of the micro-fibrilization degree of a binder resin from the crystallinity of the binder resin. Based on this, the processing conditions of mixed powder for electrode or an electrode film may be controlled. In this manner, it is possible to check and control the processing conditions easily and efficiently. In addition, the method for manufacturing a dry electrode includes a kneading step using a kneader under a low speed and high temperature and pulverization step. Therefore, there is no problem of blocking of a flow path caused by aggregation of the ingredients, which is favorable to mass production.Type: ApplicationFiled: August 5, 2022Publication date: February 9, 2023Applicant: LG Energy Solution, Ltd.Inventors: Seong-Wook Kang, Jae-Sung Han, Dong-Mok Shin, Dong-Oh Shin, Kyung-Hwan Yoon, Kwang-Ho Yoo
