Patent number: 12002962Abstract: 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: GrantFiled: August 5, 2022Date of Patent: June 4, 2024Assignee: LG Energy Solution, Ltd.Inventors: Seong-Wook Kang, Jae-Sung Han, Dong-Mok Shin, Dong-Oh Shin, Kyung-Hwan Yoon, Kwang-Ho Yoo

Patent number: 11939580Abstract: A self-circularization RNA construct that can be expressed in a DNA vector and simultaneously circularized through a self-targeting and splicing reaction to form a circRNA is disclosed. The circRNA can consist only of a gene of interest which can be a coding, non-coding, or a combination thereof. The gene of interest has the advantage of being able to rapidly express a peptide or protein. The formed circRNA has a circular structure and has a stable and high half-life because 5? and 3? ends are not exposed. Accordingly, functional RNA such as miRNA, anti-miRNA, siRNA, shRNA, aptamer, functional RNA for gene/RNA editing, ADAR (adenosine deaminase acting on the RNA)-recruiting RNA, mRNA vaccine, mRNA therapeutic agent, vaccine adjuvant, and CAR-T mRNA can be produced as a stable circRNA in cells.Type: GrantFiled: October 12, 2022Date of Patent: March 26, 2024Assignee: Rznomics Inc.Inventors: Seong-Wook Lee, Kyung Hyun Lee, Seung Ryul Han, Ji Hyun Kim, Seongcheol Kim
