Patent number: 8048573Abstract: Organic electrolytic solutions and lithium batteries using the organic electrolytic solutions are provided. One organic electrolytic solution includes a lithium salt, a mixed organic solvent consisting of a high-dielectric constant solvent and a low-boiling point solvent, and a compound represented by Formula 1 or 2 as an additive. The organic electrolytic solution and the lithium battery using the organic electrolytic solution may inhibit the reductive cleavage reaction of a polar solvent, thereby increasing capacity retention of the battery, and improving charge-discharge efficiency and battery lifetime.Type: GrantFiled: January 12, 2007Date of Patent: November 1, 2011Assignee: Samsung SDI Co., Ltd.Inventors: Seok-soo Lee, Young-gyoon Ryu, Han-su Kim

Publication number: 20110262693Abstract: A solid polymer electrolyte composite membrane and method of manufacturing the same. The composite membrane comprises a porous ceramic support having a top surface and a bottom surface. The porous ceramic support may be formed by laser micromachining a ceramic sheet or may be formed by electrochemically oxidizing a sheet of the base metal. A solid polymer electrolyte fills the pores of the ceramic support and preferably also covers the top and bottom surfaces of the support. Application of the solid polymer electrolyte to the porous support may take place by applying a dispersion to the support followed by a drying off of the solvent, by hot extrusion of the solid polymer electrolyte (or by hot extrusion of a precursor of the solid polymer electrolyte followed by in-situ conversion of the precursor to the solid polymer electrolyte) or by in-situ polymerization of a corresponding monomer of the solid polymer electrolyte.Type: ApplicationFiled: April 8, 2011Publication date: October 27, 2011Inventors: Cortney K. Mittelsteadt, Anthony B. LaConti

Patent number: 8043749Abstract: An electrolyte for a lithium ion secondary battery and a lithium ion secondary battery comprising the electrolyte. The electrolyte comprises a non-aqueous organic solvent, a lithium salt, and at least one aromatic phosphate compound. Exothermic reactions are inhibited in the battery upon overcharge or during high-temperature storage to prevent an increase in the temperature of the battery, resulting in an improvement in safety. In addition, the battery exhibits good swelling stability during high-temperature storage as well as improved cycle life characteristics. The electrolyte further comprises an ethylene carbonate-based compound. The presence of the ethylene carbonate-based compound leads to further improvements in the overcharge safety, high-temperature safety and cycle life characteristics of the battery.Type: GrantFiled: July 28, 2009Date of Patent: October 25, 2011Assignee: Samsung SDI Co., Ltd.Inventor: Jaehou Nah
