摘要： A lithium ion secondary battery includes a negative electrode that is shaped like waves in a section in the thickness direction. In the negative electrode, the ratio t1/t0 of the largest thickness t1 to the smallest thickness t0 is from 1.2 to 3.0. The negative electrode includes a thin-film negative electrode active material layer in which the ratio A/B of the volume A in a charged state to the volume B in a discharged state is 1.2 or more. The lithium ion secondary battery has high capacity, high power, long life, and improved safety. In particular, heat generation due to an internal short-circuit is significantly suppressed in a nail penetration test.

摘要： A battery pack includes: a plurality of batteries; a housing for containing the batteries; and at least one partition plate for separating the batteries from one another. The at least one partition plate includes a metal mesh and a heat insulating layer disposed on each side of the metal mesh. The heat insulating layer includes a foam material capable of foaming at a temperature of 110° C. or more and 200° C. or less, so that the thickness of the heat insulating layer increases when the foam material foams. Even when one of the batteries contained in the battery pack generates abnormal heat, the conduction of the heat to other batteries can be effectively suppressed.

摘要： A battery pack includes: a plurality of secondary batteries; a housing for containing the secondary batteries; and at least one heat insulating layer for separating the secondary batteries from one another. The at least one heat insulating layer includes a foam material capable of foaming at a first predetermined temperature of 110° C. or more and less than 200° C. When the foam material foams, gas bubbles are produced in the heat insulating layer, so that the thickness of the heat insulating layer increases. The battery pack thus has excellent safety, exhibiting a high heat insulation effect in the event of abnormal heat generation of the batteries.
