20120276439 | LITHIUM ION SECONDARY BATTERY - It is difficult to display the polarity of terminal electrodes of lithium ion batteries. With conventional lithium ion secondary batteries, since different materials are employed for the active substances that make up a positive electrode and a negative electrode, problems arise if the polarities of the electrodes are mistaken when the battery is installed. A battery has been developed using an active substance material functioning as a secondary battery even when the same material is used for the active substances that make up the positive electrode and the negative electrode, and a non-polar secondary battery has been produced. With no distinction between the terminal electrodes, attention does not need to be paid to the direction of installation, thereby simplifying the installation step. Furthermore, since there is no need to manufacture a positive electrode layer and a negative electrode layer separately, the step for manufacturing the battery is also simplified. | 11-01-2012 |

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 |

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.
