| 20080220336 | ELECTROLYTE FOR RECHARGEABLE LITHIUM BATTERY AND RECHARGEABLE LITHIUM BATTERY COMPRISING SAME - The electrolyte for a rechargeable lithium battery includes a non-aqueous organic solvent including 10 to 20 volume % of cyclic carbonate, a dinitrile-based compound, and a lithium salt. The electrolyte can prevent a voltage drop when the rechargeable lithium battery is exposed to high temperatures for a long period of time. | 09-11-2008 |
| 20080226977 | Electrolyte for lithium ion rechargeable battery and lithium ion rechargeable battery including the same - An electrolyte for the lithium rechargeable battery includes a non-aqueous organic solvent, lithium salts, vinylethylene carbonate and fluoroethylene carbonate. With this electrolyte, the ba0ttery life can be improved, and the storing property at a high temperature can be improved because the increasing rate of the battery thickness according to the increased internal pressure in the battery due to the gas generation is reduced when being kept at the high temperature, and the discharging property at a low temperature is improved because the discharge capacity can be increased when discharging at the low temperature. | 09-18-2008 |
| 20110045341 | CYLINDRICAL SECONDARY BATTERY - A secondary battery that includes a cylindrical can, an electrode assembly arranged in a jelly-role configuration within the cylindrical can and having a core extending about an axis thereof and a hollow center pin arranged within the core of the electrode assembly and having an inner diameter and an outer diameter, the outer diameter forming ones of a pair of radial lengths diametrically opposite from each other, each of said pair of radial lengths extending from the outer diameter of the center pin to an external surface of the core, wherein the sum of the pair of radial lengths is in the range of 5% to 54% of the inner diameter of the center pin. | 02-24-2011 |

| 20090155697 | Electrolyte for lithium secondary battery and lithium secondary battery comprising the same - An electrolyte for a lithium battery includes a non-aqueous organic solvent; a lithium salt; a first additive, which is 2-sulfobenzoic acid cyclic anhydride, represented by Formula 1 below, and a second additive, which is a carbonate derivative having a substituent selected from the group consisting of halogen, a cyano (CN) group and a nitro (NO | 06-18-2009 |
| 20090181301 | LITHIUM SECONDARY BATTERY - A lithium secondary battery includes a positive electrode, a negative electrode, a separator separating the positive electrode and the negative electrode, and an electrolyte. The negative electrode active material of the negative electrode includes a material that is capable of reversibly intercalating and deintercalating lithium ions and a metallic material capable of alloying with lithium. The electrolyte includes a chemical compound containing a nitrile (—CN) radical. | 07-16-2009 |
| 20100209776 | POSITIVE ELECTRODE FOR RECHARGEABLE LITHIUM BATTERY AND RECHARGEABLE LITHIUM BATTERY INCLUDING SAME - A positive electrode for a rechargeable lithium battery and a rechargeable lithium battery including the same. The positive electrode includes a positive active material, a binder, and a conductive material, wherein a weight ratio of the binder and conductive material, and the positive active material, ranges from 3:97 to 5:95 wt %, and a weight ratio of the binder and the conductive material ranges from 1.5 to 3:1. | 08-19-2010 |
