General Formula (I) Provided is an all solid state secondary-battery additive comprising a polyalkylene carbonate (I) represented by general formula (I), and by providing such additive, properties such as the charge-discharge capacity and interfacial resistance of an all-solid-state secondary battery are improved. (In general formula (I), Rand Rare each a C1-10 chain-like alkylene group or C3-10 cycloalkylene group, m is 0, 1, or 2 and n is an integer of 10 to 15000, and each R, Rand m in the polyalkylene carbonate (I) chain is independently the same or different.)

All solid state secondary-battery additive, all-solid-state secondary battery, and method for producing same

The present invention provides a metal paste composition which can obtain the calcined bodies having low volume resistivity in a wiring substrate after calcining. More specifically, the present invention provides a metal paste composition comprising a metal, an aliphatic polycarbonate, and an organic solvent.

Metal paste composition

Metal nanoparticles having improved migration resistance are provided. The present invention relates to a method for manufacturing composite nanoparticles including obtaining composite nanoparticles containing at least silver and copper in a single particle by heat treating a mixture containing an organic silver compound and an organic copper compound at a temperature of 150&#xb0; C. or more in a non-oxidative atmosphere in the presence of a tertiary amine compound represented by the general formula RRRN (wherein Rthrough Rare optionally substituted alkyl groups or aryl groups that may be the same or different, Rthrough Rmay be linked in a ring, and the number of carbon atoms in each of Rthrough Ris 5 through 18 and may be the same or different).

Composite nanoparticles and manufacturing method thereof

Copper-containing nanoparticles with excellent oxidation resistance is provided. The present invention relates to a method for manufacturing copper-containing nanoparticles including obtaining copper-containing nanoparticles that contain an organic component by heat treating an organic copper compound at a temperature equal to or higher than a decomposition initiation temperature of the compound and lower than a complete decomposition temperature of the compound in a non-oxidative atmosphere in the presence of an organic material containing a 1,2-alkanediol having 5 or more carbon atoms and/or a derivative thereof.

Copper-containing nanoparticles and manufacturing method therefor

The main object of the present invention is to manufacture, on an industrial scale, metal nanoparticles with excellent dispersion stability, and therefore provides metal nanoparticles containing a metal component, further containing at least one of phosphorus, nitrogen, and oxygen, and the average particle size being from 1 to 100 nm.
