Abstract
The invention provides a nonaqueous electrolyte battery. The non-aqueous electrolyte battery includes: a positive electrode having a positive active material layer comprising a positive active material formed on at least one surface of a positive collector; a negative electrode having a layer comprising a negative active material formed on at least one surface of a negative collector. a negative electrode active material layer of material; a separator disposed between the positive electrode and the negative electrode; and an electrolyte, wherein a condensate comprising amorphous polyacid and / or polyacid compound is formed on at least a part of the surface of the negative electrode. A colloidal coating film, the amorphous polyacid and / or polyacid compound contains one or more multielements, and at least one of the polyacid and the polyacid compound contains a valence state of 6 Polyatomic ions and polyatomic ions with a valence of less than 6.
Description
technical field [0001] The present invention relates to a nonaqueous electrolyte battery capable of suppressing gas generation of the battery and battery swelling caused by the gas generation. Background technique [0002] In recent years, with the popularization of portable devices such as video cameras and laptop personal computers, there has been an increased demand for small-sized and high-capacity secondary batteries. Secondary batteries currently in use include nickel-cadmium batteries and nickel-metal hydride batteries, both of which use alkaline electrolytes. However, the voltage of such batteries is as low as about 1.2 V, making it difficult to enhance energy density. For this reason, a lithium metal secondary battery using lithium metal having a specific gravity of 0.534 (this value is the lowest among solid simple substances), an extremely poor potential, and the largest current capacity per unit weight among metal negative electrode materials has been conducted....
