Patent number: 11945915Abstract: A method for synthesizing a pre-hydrolyzed polysilicate, wherein a polysilicate is applied as a reactant when synthesizing the pre-hydrolyzed polysilicate, and the total amount of water added in the reaction system is specified. The method is capable of omitting a condensation reaction by applying a polysilicate as a reactant, thereby significantly shortening synthesis time and reducing production costs when compared with a typical synthesis method in which alkoxysilane-based monomer compound is used as a reactant. In addition, the gelation reaction time and the weight average molecular weight can be easily controlled, and a pre-hydrolyzed polysilicate excellent in storage stability and processability can be synthesized.Type: GrantFiled: November 27, 2019Date of Patent: April 2, 2024Assignee: LG CHEM, LTD.Inventors: Kyu Reon Lee, Kyoung Shil Oh, Jong Hun Kim, Se Won Baek

Publication number: 20230261187Abstract: The present invention relates to an intermediate for preparing porous silicon oxycarbide, a method of preparing the same, and a lithium secondary battery including porous silicon oxycarbide prepared from the same as a negative electrode active material. According to the present invention, since an intermediate prepared by adding a polyhedral oligomeric silsesquioxane (POSS) to a reaction mixture for preparing silicon oxycarbide, which is composed of a polysiloxane polymer and an aromatic compound, is pyrolyzed to prepare porous silicon oxycarbide (SiOC), although the content of a free carbon region is lower compared to conventional silicon oxycarbide, the cage structure of the POSS is maintained in the pyrolysis to form many pores uniformly distributed in the SiOC matrix, and thus rapid diffusion of electrolyte ions is possible, and because the contents of SiO3C and SiO2C2 in the SiOC matrix are increased, a reversible capacity in the Si—O—C phase can be enhanced.Type: ApplicationFiled: June 18, 2021Publication date: August 17, 2023Applicant: IUCF-HYU (INDUSTRY-UNIVERSITY COOPERATION FOUNDATION HANYANG UNIVERSITY)Inventors: Hee Joon AHN, Se Hun LEE, Chang Young PARK, Kwang Hyun DO
