| 20080220327 | Electrode assembly and secondary battery with the same - An electrode assembly for a battery that can improve safety of the ceramic layer and increase lifetime capacity and high rate charge/discharge capacity and low temperature charge/discharge capacity of the electrode assembly. The electrode assembly having a porous ceramic layer coated on at least one surface of the positive electrode plate or the negative electrode plate to prevent an electrical short between the positive electrode plate and the negative electrode plate, where a main peak of pore size of the ceramic layer is in the range of 20 nm to 80 nm, and a secondary battery including the electrode assembly. | 09-11-2008 |
| 20080241674 | Electrode assembly and secondary battery including electrode assembly - An electrode assembly having a ceramic layer interposed between a positive electrode plate and a negative electrode plate, and a secondary battery including the electrode assembly includes: a positive electrode and a negative electrode plate having a ceramic layer coated on the positive electrode plate and the negative electrode plate and interposed between the two plates, and a rubber layer laminated on the ceramic layer to prevent deformation of the ceramic layer. The battery safety and reliability are improved by preventing cracking or separation of the ceramic layer from external shock by laminating the rubber layer on the ceramic layer. | 10-02-2008 |
| 20080274398 | Electrode assembly and secondary battery having the same - An electrode assembly and a secondary battery including the same. The electrode assembly is constructed with a positive electrode plate including a positive electrode coating portion, a negative electrode plate including a negative electrode coating portion, a separator interposed between the positive electrode plate and the negative electrode plate, and at least one mesh layer disposed on at least one of the positive electrode plate and the negative electrode plate. The mesh layer is wider than either the positive electrode coating portion or the negative electrode coating portion to prevent a detachment of either the positive electrode coating portion or the negative electrode coating portion. Since the mesh layer prevents the detachment of the electrode coating portions when subjected to an external impact, it is possible to improve the stability and reliability of a battery. | 11-06-2008 |
| 20080299461 | Secondary battery including positive electrode or negative electrode coated with a ceramic coating portion - A lithium secondary battery including: an electrode assembly including a positive electrode plate, a negative electrode plate, and a separator; and a case for containing the electrode assembly, wherein a ceramic coating portion is on at least one surface of the positive electrode plate or the negative electrode plate, wherein the ceramic coating portion includes a ceramic material and a binder material, and wherein the binder material includes a polymer of alkylene oxide or a copolymer thereof. | 12-04-2008 |
| 20090181300 | ELECTRODE ASSEMBLY AND SECONDARY BATTERY HAVING THE SAME - An electrode assembly of a secondary battery includes a cathode including a cathode active material layer, an anode including an anode active material layer, and a ceramic coating layer formed on at least one of surfaces of the cathode and anode that face each other. The ceramic coating layer includes a ceramic powder and a binder. The specific surface area of the ceramic powder is more than 1.5 m | 07-16-2009 |
| 20100015521 | Rechargeable battery and associated methods - A rechargeable battery and associated methods, the rechargeable battery including an anode, a cathode, wherein the cathode includes a ternary cathode-active material, a separator interposed between the cathode and the anode, an electrolyte, and a housing enclosing the electrolyte, the anode, and the cathode, wherein the electrolyte includes a lithium salt, a non-aqueous organic solvent, about 0.5 weight % to about 5 weight % of succinonitrile, and at least one of about 1 weight % to about 10 weight % of halogenated ethylene carbonate and about 1 weight % to about 5 weight % of vinyl ethylene carbonate. | 01-21-2010 |
