| 20090104344 | Method and Apparatus for Applying Electrode Mixture Paste - A method for applying an electrode mixture paste includes: a first step of unwinding a core material ( | 04-23-2009 |
| 20120164319 | Method of Forming a Metal Phosphate Coated Cathode for Improved Cathode Material Safety - The invention features a method of forming a metal phosphate coated cathode. Either a metal salt or a phosphate salt is dissolved in a nonaqueous solvent to form a first solution. The other of the metal salt or the phosphate salt (e.g., whichever compound is not dissolved in the nonaqueous solvent) is dissolved in a second solvent to form a second solution. The first solution and the second solution are mixed to form a precursor solution. A cathode material is added to the precursor solution to form a cathode-precursor solution. The cathode-precursor solution is dried to form the metal phosphate coated cathode. | 06-28-2012 |

The positive electrode active material contains (1) lithium nickel cobalt manganese oxide, and at least one type of a lithium ion acceptance capacity adjustment compound selected from (2a) lithium vanadium composite oxide, vanadium oxide, lithium vanadium phosphate, and lithium vanadium fluorophosphate and (2b) Nb | 08-23-2012 |
| 20130156942 | METHOD FOR FORMING POSITIVE ELECTRODE FOR LITHIUM-ION SECONDARY BATTERY - To provide a positive electrode for a lithium-ion secondary battery, which is highly filled with a positive electrode active material and has a high-density positive electrode active material layer. To provide a lithium-ion secondary battery having high capacity and improved cycle characteristics with use of the positive electrode. After graphene oxide is dispersed in a dispersion medium, a positive electrode active material is added and mixed to form a mixture. A binder is added to the mixture and mixed to form a positive electrode paste. The positive electrode paste is applied to a positive electrode current collector and the dispersion medium contained in the positive electrode paste is evaporated, and then, the graphene oxide is reduced, so that a positive electrode active material layer containing graphene is formed over the positive electrode current collector. | 06-20-2013 |
