Embodiment Construction

[0028] Here, referring to the embodiment of the present invention Figure 1 ~ Figure 3 Be explained.

[0029] This specific implementation will be as Figure 4 ~ Figure 5 A non-aqueous electrolyte secondary battery having basically the same structure as the conventional example will be described. Moreover, even in Figure 1 ~ Figure 3 in, such as Figure 4 ~ Figure 5 Structural components shown having the same functions as those of the prior example are given the same reference numerals.

[0030] The structures of the power generating element 1, the battery container 2, and the battery cover 3 of the non-aqueous electrolyte secondary battery in this embodiment are the same as those of the conventional example. In addition, the positive terminal 4 on the battery cover 3 is insulated and sealed by the terminal insulating sealing materials 5 and 6, and the protrusion 4a of the positive terminal 4 is connected and fixed with the positive lead plate 7 by riveting. This structur...

Abstract

A battery including: a power generating element having a positive electrode, a negative electrode, and a separator; a battery case for housing the power generating element; a battery cover for closing the battery case; and a lead for electrically connecting a terminal provided for the battery cover and the positive electrode or the negative electrode, wherein a part in which the lead and the positive electrode or the negative electrode are electrically connected to each other is sandwiched by an insulating member.

Description

technical field [0001] The present invention relates to the technique of a battery in which a power generating element is put into a battery container and sealed with a battery cover, and terminals are provided on the battery cover and connected to electrodes of the power generating element through the terminals. Background technique [0002] Figure 4 An example of the original structure of the non-aqueous electrolyte secondary battery is shown. In this non-aqueous electrolyte secondary battery, a power generating element 1 is housed in a battery container 2 , and the opening of the battery container 2 is closed with a battery cover 3 . The power generating element 1 is formed by winding a strip-shaped positive electrode 1a and negative electrode 1b through a separator 1c into a cylindrical shape. The positive electrode 1a is an object coated with a positive active material on the surface of a strip-shaped aluminum foil of the current collector base material, and the negat...
