摘要： A non-aqueous electrolyte battery with improved cyclic characteristics and battery capacity at high temperature and capable of suppressing the evolution of gas during storage at high temperature while maintaining favorable cyclic performance, wherein vinylene carbonate (VC) and α-angelica lactone (4-hydroxy-3-pentenic acid γ-lactone) are contained in the electrolyte, and whereby a highly soft and flexible coating film with α-angelica lactone is formed on the surface of the negative electrode without reducing the initial charging efficiency of the battery. Since a mixed coating film comprising VC and α-angelica lactone is formed on the soft and flexible coating film and the mixed coating film has higher thermal stability at high temperature than that of the coating film formed only with VC, the cyclic characteristics of the battery at high temperature can be improved while enhancing the suppression of gas evolution during storage at high temperature.
摘要翻译：一种在高温下具有改善的循环特性和电池容量并且能够在保持良好循环性能的同时在高温保存期间抑制气体逸出的非水电解质电池，其中碳酸亚乙烯酯（VC）和当归内酯（4-羟基 -3-戊烯酸γ-内酯），由此在负极的表面上形成具有α-当归内酯的高度柔软且柔软的涂膜，而不会降低电池的初始充电效率。由于在柔软且柔软的涂膜上形成包含VC和α-当归内酯的混合涂膜，并且混合涂膜在高温下的热稳定性高于仅用VC形成的涂膜的热稳定性，所以电池的循环特性在高温保存期间，可以提高高温下的气体放出抑制。

摘要： The invention provides a method for evaluating the safety of a battery under an internal short-circuit condition. The battery includes: an electrode group including a positive electrode, a negative electrode, and an insulating layer for electrically insulating the electrodes, which are wound or laminated; an electrolyte; a housing for housing the electrode group and the electrolyte; and a current-collecting terminal for electrically connecting the electrode group and the housing. The method of the invention includes: placing a foreign object at a location inside the electrode group of the battery where the positive electrode and the negative electrode face each other; and pressing the location by the pressure applied by a pressing tool to locally crush the insulating layer between the positive and negative electrodes, thereby causing an internal short-circuit. The contact area of the electrode group and the pressing tool during the pressing is larger than the area of a rectangle circumscribed about the foreign object. A short-circuit test is conducted at a given location inside the battery to comprehensively evaluate the safety of the battery under an internal short-circuit condition.
