| 20120064406 | ELECTRODE MATERIAL, METHOD FOR PRODUCING SAME, AND LITHIUM ION SECONDARY BATTERY - Secondary batteries for automobiles require good input/output characteristics and low internal resistance. Conventionally, the surface of an active material is coated with metal particles to reduce the internal resistance of a battery, but without achieving remarkable improvement in the conductivity of the active material or decreasing the internal resistance of the battery since an oxide film is formed on the metal particle surfaces. The present electrode material is produced by mixing and dispersing an active material and a metal source compound, then depositing metal particles on the surface of the active material by thermal decomposition, vapor phase reduction, liquid phase reduction or a chemical reaction combining any of these. Since an oxide film is not formed on the metal particles, an electrode material having high conductivity is obtained. The electrode material decreases the internal resistance of a battery and improves the input/output characteristics of a battery. | 03-15-2012 |
| 20120015234 | LITHIUM ION SECONDARY BATTERY AND METHOD FOR MANUFACTURING SAME - A conventional, multilayer, all-solid-state, lithium ion secondary battery where an electrode layer and an electrolyte layer are stacked has a problem that it has a high interface resistance between the electrode layer and the electrolyte layer and has a difficulty in increasing the capacity of the battery. A battery has been manufactured by applying pastes of a mixture of an active material and a solid electrolyte to form electrode layers and baking a laminate of electrode layers and electrolyte layers at a time. As a result, a matrix structure including the active material and the solid electrolyte has been formed in the electrode layers, so that a battery with a large capacity and a reduced interface resistance between the electrode layer and the electrolyte layer has been successfully achieved. | 01-19-2012 |
| 20110003212 | LITHIUM ION SECONDARY BATTERY AND PROCESS FOR PRODUCING THE SECONDARY BATTERY - A multilayer whole solid-type lithium ion rechargeable battery has hitherto been produced by stacking green sheets of a positive electrode layer, a solid electrolyte layer, and a negative electrode layer, which are formed of respective materials different from each other in coefficient of thermal expansion, and firing the layers at a time. This technique poses problems of delamination and nonlamination attributable to a difference in shrinkage. The problems can be solved by forming green sheets with the addition of a sintering aid to each starting material powder for the positive electrode layer, the solid electrolyte layer, and the negative electrode layer and performing control, by setting the additive rate of the sintering aid and the firing temperature, so that the shrinkages of the respective green sheets are substantially equal to each other. Consequently, unfavorable phenomena such as delamination can be prevented. | 01-06-2011 |

| 20100216032 | LITHIUM ION RECHARGEABLE BATTERY AND PROCESS FOR PRODUCING THE LITHIUM ION RECHARGEABLE BATTERY - Conventional ion rechargeable batteries having an electrode layer on an electrolyte layer suffer from an impurity layer formed at the interface, degrading performance. Conventional batteries with no such impurity layer have a problem of weak interface bonding. In the present invention, in a baking process step after an electrode layer is laminated on an electrolyte layer, materials for an electrode layer and an electrolyte layer are selected such that an intermediate layer formed of a reaction product contributing to charging and discharging reactions is formed at the interface of the electrode layer and the electrolyte layer. In addition, a paste that an active material is mixed with a conductive material at a predetermined mixing ratio is used to form a positive electrode layer and a negative electrode layer. Reductions in electrode resistance and interface resistance and improvement of charging and discharging cycle characteristics are made possible. | 08-26-2010 |
| 20100075219 | LITHIUM ION SECONDARY BATTERY AND PROCESS FOR MANUFACTURING THE SAME - In multilayer wholly solid lithium ion secondary batteries, a laminate having a collector layer of material with high conductivity superimposed on an active material layer has been disposed so as to attain a lowering of battery impedance. Consequently, in the fabrication of each of positive electrode layer and negative electrode layer, stacking of three layers consisting of an active material layer, a collector layer and an active material layer has been needed, thereby posing the problem of complex processing and high production cost. In the invention, a positive electrode layer and a negative electrode layer are fabricated from paste consisting of active material mixed with conductive substance in a given mixing ratio, and no collector layer is disposed. This realizes process simplification and manufacturing cost reduction without deterioration of battery performance and has also been effective in enhancing of battery performance, such as improvement to cycle characteristics. | 03-25-2010 |
