Publication number: 20240136531Abstract: A conductive composite material, a method of preparing the same, and a secondary battery including the same. The conductive composite material may increase the proportion of an active material when forming an electrode by chemically bonding a conductive material and a binder to each other. A method of preparing the conductive composite material comprises ionizing carbon-based particles in a predetermined polarity, ionizing PTFE particles in a polarity different from that of the carbon-based particles, and chemically bonding the ionized carbon-based particles and the ionized PTFE particles, which are ionized in different polarities, to each other.Type: ApplicationFiled: September 20, 2023Publication date: April 25, 2024Inventors: Seung Min Oh, Sung Ho Ban, Sang Hun Lee, Ko Eun Kim, Yoon Sung Lee, Chang Hoon Song, Hyeong Jun Choi, Jun Myoung Sheem, Jin Kyo Koo, Young Jun Kim

Patent number: 8271209Abstract: Methods, systems and computer program products for identifying components of an unknown mixture using spectral analysis techniques. The method includes comparing the spectrum of the unknown mixture with the spectra of library compounds to obtain candidate mixture combinations. A model is generated for each of the candidate mixture combinations based on a modeling metric. A residual spectrum is computed corresponding to each of the candidate mixture combinations by removing the spectrum of each of the compounds of the candidate mixture combination from the spectrum of the unknown mixture. One or more potential compounds are identified by comparing the residual spectrum with the spectrum of library compounds. The potential compounds are added to the candidate mixture combinations to generate an updated list of the candidate mixture combinations. The search algorithm repeats the steps described above on the updated candidate mixture combinations, until a first termination condition is satisfied.Type: GrantFiled: December 18, 2009Date of Patent: September 18, 2012Assignee: General Electric CompanyInventors: Sridhar Venkataraman Dasaratha, Thirukazhukundram Subrahmaniam Vignesh, William Scott Sutherland, Young Kyo Lee
