摘要： PROBLEM TO BE SOLVED: To solve problems where oxidizing catalytic function is enhanced especially at a positive electrode at high temperatures, ordinary nonaqueous solvent is oxidized and decomposed on a surface of the positive electrode, discharge characteristic is deteriorated due to decrease in conductivity of electrolytic solution, decomposed products (for example carbon dioxide gas and the like) generate as gasses, and in worst case, liquid leaks out of the battery in a nonaqueous secondary battery using a nonaqueous organic solvent which is not electrolyzed at high voltage. SOLUTION: For solving these problems, many kinds of electrolytic solutions containing additives for generating coating films on a positive electrode and on a negative electrode have been proposed. Even though these additives have the effect of suppressing generation of gasses, they induce deterioration in characteristics in charging and discharging of a battery, especially in high- efficiency discharge and low-temperature discharge because many of the additives form highly resistive coating films on the electrodes. Nanaqueous electrolytic solution containing at least 6-substitution-1,3,5-triazine-2,4-dithiol and its derivative are used.

摘要： PROBLEM TO BE SOLVED: To allow recharging by mainly forming an electrolyte with a lithium ion conducting inorganic solid electrolyte, and containing a first transition metal chalcogenide or a lithium transition metal chalcogenide and a second transition metal chalcogenide or a lithium transition metal chalcogenise meaner than them in a negative electrode. SOLUTION: First and second transition metal chalcogenides include Fe, Co, Ni and V, Ti, Cr, Mo, Nb, Mn. When a negative electrode contains Li2 FeS2 and LiTiS2 having a meaner reaction potential as the first and second transition metal chalcogenides, for example, the reaction of the equation I occurs prior to the metal lithium deposition reaction of the equation II, when the size of the charging current exceeds the reaction speed. The reaction speed of the equation III is considerably large, the reaction of the equation II rarely occurs by charging/discharging actions as a whole, and charge/discharge characteristic may improved. A chalcogen element is set as sulfur, and a sulfide is preferably used as the main component of the inorganic solid electrolyte.

摘要： PROBLEM TO BE SOLVED: To perform a working such as the refining or uniform mixing with an electrode active material of a solid electrolyte without loosing the electrochemical performance of the solid electrolyte by using a benzene derivative having an electron donative functional group in m-position as a dispersant for the solid containing a sulfide. SOLUTION: As a dispersant for an inorganic lithium ion conductive solid electrolyte containing a sulfide, a benzene derivative having an electron donative functional group in m-position represented by the formula is used. As the electron donative functional group, alkyl groups such as -CH3 , -C2 H5 , -C3 H7 , -C4 H9 and the like are included. The water content of the benzene derivative is preferably 0.5% or more. The solid electrolyte is apt to cause an electrophilic reaction when it makes contact with the benzene derivative. Therefore, the solid electrolyte is preferably mainly composed of a sulfide containing silicon. For grinding of the solid electrolyte using this dispersant, a medium stirring type grinder such as mortar or ball mill, a tower grinder, or a wet high-speed rotary mill such as stirring tank type are used.
