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 |
20110151337 | ELECTROLYTE FOR LITHIUM BATTERY AND LITHIUM BATTERY COMPRISING SAME - An electrolyte for a lithium battery includes a non-aqueous organic solvent, a lithium salt, and an additive comprising a) a compound represented by the following Formula (1), and b) a compound selected from the group consisting of a sulfone-based compound, a poly(ester)(metha)acrylate, a polymer of poly(ester)(metha)acrylate, and a mixture thereof: | 06-23-2011 |
20110206982 | LITHIUM ION SECONDARY BATTERY - A lithium ion secondary battery is provided. The lithium ion secondary battery generally comprises an electrode assembly, a container for accommodating the electrode assembly; and an electrolyte. The electrode assembly comprises two electrodes having opposite polarities and a separator. The separator comprises a porous membrane comprising clusters of ceramic particles. The porous membrane is formed by bonding the particle clusters with a binder. Each particle cluster is formed either by sintering or by dissolving and re-crystallizing all or a portion of the ceramic particles. The ceramic particles comprise a ceramic material having a band gap. Each particle cluster may have the shape of a grape bunch or a lamina, and may be formed by laminating scale or flake shaped ceramic particles. | 08-25-2011 |
