Publication number: 20120255604Abstract: An electrolyte for a dye-sensitized solar cell, the electrolyte including an organic solvent; a redox derivative; and an additive including a linear carbon chain, wherein the additive has an ionic or non-ionic neutral functional group located at one or more ends of the linear carbon chain. The viscosity of the high-density electrolyte is reduced, whereby the ionic conductivity of the electrolyte is increased, and the leakage of the electrolyte from the dye-sensitized solar cell is prevented. Therefore, a dye-sensitized solar cell including the electrolyte exhibits enhanced durability and efficiency such as in terms of fill factor (FF).Type: ApplicationFiled: September 22, 2011Publication date: October 11, 2012Applicant: Samsung SDI Co., Ltd.Inventors: Moon-Sung KANG, Ji-Won Lee, Si-Young Cha

Patent number: 8283074Abstract: Metal complex salts may be used in lithium ion batteries. Such metal complex salts not only perform as an electrolyte salt in a lithium ion batteries with high solubility and conductivity, but also can act as redox shuttles that provide overcharge protection of individual cells in a battery pack and/or as electrolyte additives to provide other mechanisms to provide overcharge protection to lithium ion batteries. The metal complex salts have at least one aromatic ring. The aromatic moiety may be reversibly oxidized/reduced at a potential slightly higher than the working potential of the positive electrode in the lithium ion battery. The metal complex salts may also be known as overcharge protection salts.Type: GrantFiled: August 15, 2008Date of Patent: October 9, 2012Assignee: UChicago Argonne, LLCInventors: Khalil Amine, Zhengcheng Zhang, Zonghai Chen

Patent number: 8277972Abstract: A non-aqueous electrolyte solution for a lithium secondary battery includes a lithium salt and a carbonate organic solvent. The non-aqueous electrolyte solution further includes a fluoro group-containing sulphonate compound expressed by Chemical Formula 1. When the non-aqueous electrolyte solution is employed for a lithium secondary battery, low-temperature discharging characteristics and life cycle characteristics are greatly improved. Also, even though a battery is stored at a high temperature in a fully-charged state or a charging/discharging process is under progress, the decomposition reaction of a carbonate-based organic solvent is restrained, thereby solving the swelling problem and improving high-temperature life cycle characteristics.Type: GrantFiled: March 9, 2009Date of Patent: October 2, 2012Assignee: LG Chem, Ltd.Inventors: Jong-Ho Jeon, Jeong-Ju Cho, Ho-Chun Lee
