摘要： Positive and negative electrode plates are respectively joined to positive and negative electrode terminals through leads. At least one of the leads joined to the positive or negative electrode plate is made of a stack of first and second metal layers. The first metal layer has a resistance higher than that of the second metal layer. The second metal layer has a melting point lower than that of the first metal layer. When a short-circuit current flows in the secondary battery, current is concentrated in the second metal layer to cause a blowout of the second metal layer, and then, an increase in an heat generation amount due to an increase in a current density of a short-circuit current flowing in the first metal layer causes a blowout of the first metal layer, thereby causing a blowout of the lead to interrupt the short-circuit current.
摘要翻译：正极板和负极板通过引线分别连接到正极端子和负极端子。连接到正极板或负极板的引线中的至少一个由第一和第二金属层的叠层制成。第一金属层的电阻高于第二金属层。第二金属层的熔点低于第一金属层的熔点。当在二次电池中流过短路电流时，电流集中在第二金属层中，引起第二金属层的吹出，由于电流密度增加导致发热量增加在第一金属层中流动的短路电流导致第一金属层的吹出，从而导致引线的吹出中断短路电流。

摘要： There is provided a film measuring device capable of accurately and easily measuring the thickness of a microporous film formed on a battery electrode plate over the entire area of the film. A color CCD sensor 8 shoots the microporous film. A video board 11 converts a color tone of a color image signal obtained by the image pickup into gradation data of respective color components of RGB. After the data conversion, an image processing board 12 extracts line images of the respective color components. A calculator 14 obtains the thickness of the microporous film by referring to pre-measured film thickness reference values corresponding to the gradation data of the green or blue color component, which are stored in a table storage 13 as reference thickness table data, using the gradation data of the line image of the green color component or the blue color component as lookup data.

摘要： A separator for a lithium secondary battery includes a high molecular porous film with a shut-down function and a heat-resistant porous layer integrally formed on each side of the high molecular porous film. The heat-resistant porous layers contain a heat-resistant high-molecular material and a ceramic filler. By using the separator, the occurrence of a short-circuit due to the melting and shrinkage of the high molecular porous film is prevented. Also, in the event of a short-circuit and the generation of heat higher than the melting point of the material of the high molecular porous film, the expansion of the short-circuit is prevented, so that the safety of the lithium secondary battery is improved.
