Publication number: 20100252783Abstract: Compositions of ambient-curable anisotropic conductive adhesive comprising an ambient-curable epoxy resin system and a conductive powder are proposed. It can be cured under ambient conditions using common magnet for clamping mechanism. This greatly simplifies many electronic repairs or Do-It-Yourself types of application. This anisotropic conductive adhesive can also be applied using traditional hot-bar laminator, but at lowered temperatures, and this is bound to open up new application possibilities.Type: ApplicationFiled: April 7, 2009Publication date: October 7, 2010Inventor: Syh-Tau Yeh

Patent number: 7806974Abstract: A viscosity controllable highly conductive ink composition. The highly conductive ink composition comprises an organic solvent, nanoscale metal particles or metallo-organic decomposition compounds, and a thermally decomposable organic polymer. Specifically, since the thermally decomposable polymer can increase the viscosity of the highly conductive ink composition and be removed by subsequent thermal treatment, so as to decrease the impact on conductivity by organic polymer. Therefore, a viscosity-controllable conductive ink composition is obtained.Type: GrantFiled: May 24, 2006Date of Patent: October 5, 2010Assignee: Industrial Technology Research InstituteInventors: Gue-Wuu Hwang, Bao-Tsan Ko, Yi-Shin Lin

Publication number: 20100243964Abstract: Disclosed are a composite which can be used as an electrode active material for a secondary battery, and the secondary battery comprising the same. The composite includes: a first material selected from the group consisting of metals and metalloids capable of being reversibly alloyed with lithium; a second material selected from the group consisting of metals incapable of being alloyed with lithium, compounds containing the metals, and compounds containing metals or metalloids capable of being irreversibly alloyed with lithium; and a third material which is at least one kind of metal having a higher electrical conductivity than the second material, wherein a content of the third material ranges from 10 to 10,000 ppm based on the total weight of the composite. In the composite, the third material increases the electrical conductivity, thereby forming an electrical conducting path between materials within the composite. This allows the volume of a battery to be uniformly changed during the charge/discharge.Type: ApplicationFiled: May 4, 2010Publication date: September 30, 2010Applicant: LG CHEM, LTD.Inventors: Yongju LEE, Insung Uhm, Seungyoun Choi, Jeyoung Kim, Dong Sub Jung
